FROM Manhattan GMAT Blog: How to Review a Data Sufficiency Question |
You’ve heard it here before: reviewing practice problems is even more valuable than doing them. Here’s a step-by-step guide to reviewing your GMAT Data Sufficiency problems. Which Data Sufficiency questions should I review? If you had infinite time, you’d want to review every Data Sufficiency problem you do. But, let’s be realistic! You have my permission to not review these types of problems:
Okay, so you have a list of problems to review. What does reviewing a problem actually look like? Reviewing a Data Sufficiency problem The first step is to redo the problem. However, you’re going to do the problem differently this time. When you redo while reviewing, don’t use a timer. Feel free to use any outside resources you’d like, such as a calculator or the All the Quant Guide. That’s right — you’re allowed to “cheat” as much as you want! The only thing you can’t use is the explanation. I’ll say that again, because it really matters: DO NOT READ THE EXPLANATION (YET)! When you read the explanation too soon, you’re robbing yourself of a chance to solve the problem. And you’ll learn more from solving the problem—even if it’s a struggle and even if you need to cheat!—than you will from watching someone else solve it. If you get stuck, check the explanation, but stop reading as soon as it gives you a good clue. Then, go back to your own paper and try to finish the work yourself. If you absolutely can’t get anywhere, even with multiple clues from the explanation, the problem might be too hard right now. Save it for later — and if this happens repeatedly with the same type of problem, that’s a sign that you should review that topic! Once you’re satisfied with your own redo of the problem, feel free to read the rest of the explanation. Take note of anything that the explanation did that you didn’t do, or vice versa. Sometimes, the explanation can point you in the direction of a faster or simpler solution. Learning from a Data Sufficiency problem Now, it’s time to take some notes. But you aren’t just going to write down how to solve the problem. That would help you remember how to solve this exact problem, but that’s not the point. Here’s what your goals really are at this stage:
A bookstore that sells used books sells each of its paperback books for a certain price and each of its hardcover books for a certain price. If Joe, Maria, and Paul bought books in this store, how much did Maria pay for 1 paperback book and 1 hardcover book? (1) Joe bought 2 paperback books and 3 hardcover books for $12.50. (2) Paul bought 4 paperback books and 6 hardcover books for $25.00. Do the problem now! Next, we’ll walk through which notes you should take in your problem log. A Data Sufficiency problem has two different things you need to analyze while solving: the question stem, and the statements. Take some notes on each. First, write down anything that stands out about the question stem, and what you think you should do when you see those things in a Data Sufficiency question. Your exact notes will vary depending on your strengths and weaknesses, how you solved the problem, and why you’re reviewing it. Here are some examples. Student 1 spent too long on this problem because she dove into the statements without understanding the problem. She didn’t realize, until too late in the process, that solving with equations would have been much simpler. Here are her notes on the question stem: Word problem = turn into variables BEFORE dealing w/ statements! Student 2 read the question stem and assumed she’d need to solve for the price of each book individually, instead of solving for the sum of two prices. Here are her notes: Look for “combos” where the ? asks for a sum: hardcover AND paperback price = H + P Could still solve even without H or P separately Write down the exact question, don’t assume! Student 3 got this one right, but still thought it was an interesting problem! Here are her notes: Q is “what is H + P” : look out for tricky statements that tell you the sum, like “2H + 2P = 10”! Next, go through the statements one at a time. Here’s where things really get interesting. If you missed the problem, then you either thought an insufficient statement was actually sufficient, or thought a sufficient statement was actually insufficient. Figure out where things went wrong first: which statement(s) did you analyze incorrectly? (For a very deep dive into these two types of mistakes, check out our articles on type 1 errors and type 2 errors.) If you thought a statement was sufficient and you were wrong, figure out why you thought it was sufficient. Then, in your notes, prove that it was insufficient. That will probably involve writing down specific cases, even if you wouldn’t take the time to do that on test day. When you’re reviewing, take all the time you need! If you thought a statement was insufficient and you were wrong, figure out why you thought it was insufficient. Then, prove that it was sufficient. That means demonstrating to yourself, in your notes, exactly how the statement helps you answer the question, and what answer it leads to. Student 1 got the problem right eventually, but realized when reviewing that she didn’t need to test cases. Here are her notes on the statements: DS word problem: turn into math equations and see if the algebra is easy BEFORE you think about cases…cases work but take a long time! Student 2 made the first type of mistake when she put the statements together. She thought the statements were sufficient together, but they actually weren’t. Let’s see her notes: Statements were insufficient together! I thought they were sufficient b/c there were two equations and two variables in the question. Proof: statements simplify to the same thing, 2p + 3h = 12.5. If the statements are the same, C CAN’T be the right answer. The answer must be either D or E. Word problem to algebra = check to make sure the statements aren’t identical, don’t assume C if it seems easy! Student 3 got this one right, but she’s still taking notes so she remembers any tricks this problem tried to play! Here are her notes. DS linear equations: simplify statements to double check that the statements aren’t = to each other. If 2 statements are different, you can solve for two variables. But if they’re the same, you can’t solve at all (unless the statement is the same as the question.) By the way, the answer to the question was (E). I didn’t tell you until now because of exactly what I wrote earlier — the more you play around with a problem on your own before letting somebody else tell you what to do, the more you’ll remember about it later. What do I do with all of these notes? From each problem you’ve reviewed, you’ve learned something about the GMAT—and you’ve hopefully learned something about how you tend to approach problems and the mistakes you make most often. What do you do with all of this information? GMAT instructor Elaine Loh suggests a method in this article that everybody should try out. For each problem you learned something from, set a date about two weeks in the future to redo it again. For instance, you could have a study session once per week where you redo all of the old problems from a couple of weeks ago. Write down these dates in your problem log, and build a habit of checking it regularly and actually redoing the problems you’ve listed. Also, she recommends that when you have a few minutes of spare time, you simply read over the notes you’ve taken in your problem log. No need to do anything fancy — just quickly reread your takeaways once or twice a week, to jog your memory of the interesting DS problems you’ve reviewed so far. If Data Sufficiency is a strong area for you, it’s okay to keep your problem logging low-key. Just jot down a couple of notes on problems you missed (unless they’re way too hard!). But if you want to improve your DS performance, be more aggressive in reviewing DS problems for a couple of weeks, and you may notice a change in how you think about these problems.

FROM Manhattan GMAT Blog: How To Read A Reading Comp Passage |
How can we efficiently tackle Reading Comp Passages on the GMAT? What are we supposed to do and look for during the initial few minutes before we start to answer the first question? Note: this article doesn’t address how to answer reading comprehension questions; it focuses on the initial read-through and note-taking. If you do that well, though, then that should help you answer any kind of question. Goals for Reading Comp Problems Whenever we start a specific type of problem, we should have certain goals in mind (depending, of course, on what that problem type is). Reading Comprehension (RC) is no exception. First, we have some timing goals. I aim to complete an initial read-through of an RC passage in 2 (shorter) to 3 (longer) minutes. I try to answer general questions (e.g., main idea) in about 1 minute and specific questions in about 1.5 to 2 minutes. I also take some short notes while I read through the passage; these notes will be based upon the goals discussed in the next several paragraphs. My notes will be heavily abbreviated; see the Taking Notes section below for more on this topic. Next, we have some goals for the initial read-through of the passage. Every passage has a topic and what I call The Point. The topic is what you would probably expect: the basic topic under discussion in the passage. The Point is the main reason the author is writing this specific passage (you can also think of The Point as the thesis statement). For instance, a passage topic might be the curious decline of bees in recent years (entire hives have been dying, losing the ability to find their way back to the hive, and so on). The Point might be that, out of three possible causes (all mentioned in the passage), a certain pesticide is the most likely cause (according to the author). Back to our Goal: when I read the passage, I need to make sure I understand The Point, not just the topic. Further, I also need to make sure I understand the purpose of each paragraph. These passages follow the same rules we’re supposed to use when we write an essay: each paragraph should have one distinct purpose or message (and, often, that message is delivered via a topic sentence, usually the first or second sentence of the paragraph). Finally, I also need to make sure that I do NOT fully understand or remember all of the detail in each paragraph. That was not a typo. I’m trying to read this passage in 2 to 3 minutes maximum; I don’t have time to try to fully understand, let alone remember, all of the detail. My goal is to know in which paragraph the different kinds of detail reside–that’s all. Wait, How Can I Get Away With NOT Understanding the Detail? This is where we can take advantage of the fact that the GMAT is a standardized test. An individual test-taker is given only about half of the questions that were written for that passage. That little piece of knowledge has major implications for how we conduct the initial read-through. I know that I’m going to have to understand The Point, because that permeates the entire passage and even, to some extent, every question that I answer. I also know that I will not get asked about every detail on the screen because I’m never going to see half of the questions. So why learn all of that annoying detail unless I know that I’m going to get a question about it? (And I won’t know that until the question pops up on the screen.) Instead, as we discussed above, my goal for the detail is to know in which paragraph it resides. That way, if I do get a question about the chemical mechanism by which the pesticide affects a bee’s nervous system, I’ll immediately know that I can find that detail in paragraph 2. I won’t have any idea how to answer the question yet; I’ll have to read that detail now to see whether I can figure it out. Note: did you hit a word you don’t know? Skip it. Is some sentence really convoluted? If it’s the first sentence of a paragraph, use your SC knowledge to find the subject and verb, just to get a basic understanding of what it says. If it’s a detail sentence, skip it. Reading Comprehension: The Initial Read-through Most of the time, The Point can be found in one discrete sentence somewhere in the passage (though sometimes we have to combine two sentences to get the full Point). Most often, The Point can be found in the first few or last few sentences of the entire passage, but it is possible for The Point to show up anywhere. So, a new passage pops up on the screen and we, naturally, start reading. Read the first sentence, then stop. Rephrase it in your mind (put it into words that you can understand very easily), and jot down a note or two. Then do the same with the second sentence. Once you think you understand the purpose of that one paragraph, you can start skimming the rest of the paragraph. While you skim, you’re trying to make this distinction: is this information just detail that goes along with whatever I decided was the purpose of this paragraph? Or is this information something new: does it represent a new idea or a change of direction? If it’s just detail, jot down the basic kind of detail it is (e.g., “bees dying”) and move on. If it represents a new idea or change of direction, then pay a little more attention and take some short notes. Do the same with the other paragraphs, though you can be a bit more aggressive about skimming. If, for example, you think you understand the purpose of the second paragraph after reading only the first sentence, that’s fine. Start skimming (but take note of anything that represents a new direction). When you’re done, take a moment to articulate The Point to yourself. Is that already in your notes? Put a star next to it. If it isn’t in your notes, jot it down. Taking Notes Your notes should be heavily abbreviated–much more aggressively abbreviated than notes you would typically take at work or school. In fact, if I look at my notes for a passage a few days later, I should have a lot of trouble figuring out what they say (without using the passage as a reference). How can we get away with abbreviating this heavily? Again, we’re taking advantage of the nature of this test. You’re going to spend perhaps 6 to 8 minutes with this passage and then you can forget about it forever. You don’t need to commit anything to long-term memory, nor do you need to take notes from which you can study in a week. (Of course, if you’re just practicing, you are going to review your work later, but you should still practice as though it’s the real thing.) Analyzing Your Work Everyone already knows that it’s important to review your work on the problems you do, but did you know that it’s also important to review how you read and take your notes? When you’re done with a passage and the associated questions, start your review with the passage itself. When you were done reading (but before you answered questions), what did you think The Point was? What did you think the purpose of each paragraph was? Did that knowledge or understanding change as you worked your way through the questions? If you misunderstood something after the first read-through, why do you think you misunderstood it? Did you read too quickly and overlook something? Did you not take the time to rephrase what you read? How could you do this better next time? Next, match your initial notes to your current knowledge of what information is contained in the passage. Were you able to find the right paragraph easily when answering a specific question? If not, why not? What should you have jotted down on the initial read-through to make that easier? Conversely, did you have too much information jotted down? Maybe you were able to answer a specific question just from your notes, or maybe you had a lot of detail written down that you never had to use. If so, you wrote down too much information and you spent too much time on the initial read-through. Could you have abbreviated even more? Write down what that might have looked like, from the beginning. (In general, if you feel your notes were fairly far from your ideal for any reason, then re-write the notes the way you should have written them the first time.) Take-aways (1) You do NOT want to learn or comprehend every single thing that the passage says (2) Know your goals: (a) Find The Point (b) Find the purpose of each paragraph (c) Know where (in which paragraph) to find different kinds of detail (3) Practice sticking to your timing and practice abbreviating heavily (4) When you review your work, also review how you read and took notes on the passage RELATED: What NOT to Read on Reading Comprehension Passages Don’t forget that you can attend the first session of any of our online or in-person GMAT courses absolutely free.

FROM Manhattan GMAT Blog: How to Review a Sentence Correction Question |
I’ve often heard that studying GMAT Verbal feels less straightforward than studying Quant. Even though Quant is tough, it does have a lot of clear rules and techniques to memorize. Verbal, on the other hand, feels much fuzzier. But is that really the case? Start by reading this article, which investigates whether GMAT Verbal questions are “fair.” Once you’re thinking methodically about the rules of GMAT Verbal, come back to this article to learn how to deep dive a Sentence Correction problem. Which Sentence Correction questions should I review? Ideally, you’d review every problem you do. But you don’t have to go through the whole process in this article every single time. The most important Sentence Correction problems to review are ones that fall into these categories:
Reviewing Sentence Correction Problems Once you’ve decided to review a Sentence Correction question, commit to reviewing it at least twice. When you review for the first time, do it shortly after originally doing the problem — for instance, on the following day. As with any type of problem, the first step is to redo the problem. Take it easy this time! Don’t use a timer. Your goal right now is to dig into the problem and reflect. You can even look up the grammar rules in the All the Verbal guide while you’re trying to figure it out. If you got the problem wrong the first time, you have a specific task to do at this point. Look at what the right answer was, but don’t look at the explanation at all just yet. Instead, try to figure out on your own why the right answer was right. It’s fine if you have to guess why it was right. If you think about it on your own before reading the explanation, you’re far more likely to remember the explanation long-term. If you really get stuck, glance at the explanation, but try not to passively read the whole thing. For instance, you might glance at the explanation for just one of the answer choices at a time. Learning from a Sentence Correction problem The next step is where the most valuable learning happens. It’s time to reflect on the problem in a methodical, organized way, and take notes that will help you later on. Before we go further into the process, let’s do a Sentence Correction problem from GMATPrep as an example: Displays of the aurora borealis, or “northern lights,” can heat the atmosphere over the arctic enough to affect the trajectories of ballistic missiles, induce electric currents that can cause blackouts in some areas and corrosion in north-south pipelines.
The Big Picture Start by looking at the whole problem again, after redoing it. What major lessons are worth remembering? If you missed it, was there something about the problem you should have noticed? Here are some examples. Student A spent a long time solving this problem, because they spent 90 seconds going back and forth between the answer choices starting with “to” and the ones starting with “that.” In the end, they weren’t able to make a confident decision. Here are their brief big-picture notes:
Focusing on the splits Next, zoom in on the differences among the answer choices. When you actually solve a Sentence Correction problem, you’ll do so one split at a time. For each split in the problem, make sure you can explain the following:
Student A
Student B focused on the Parallelism issue right away, but they struggled to pick the right answer because they misunderstood the sentence structure. That’s what their notes focus on:
Next-level Sentence Correction review Depending on your own strengths and weaknesses, you may or may not stop there. It’s great if you can just get one or two clear, actionable lessons out of each Sentence Correction problem you review. However, if Sentence Correction is a weakness for you, you may want to add more steps to your review process. For example, if you have a hard time finding the subject and verb of a complex sentence, you could try breaking the sentence down to its core every time you review a problem. If you’re struggling to remember the modifier rules, you could jot down each different type of modifier that appears in the sentence. It can also be helpful to jot down what caused you to miss a problem. This will help you notice patterns you may otherwise miss. Did you miss a problem because you skimmed over a small but critical word late in the sentence? Or because you picked the answer that “sounded okay” rather than the one that followed all of the grammar rules? Write it down! You could be making the same mistake more often than you realize. Once you’ve taken some notes on the problem, set it aside for a week or two. If you’re using a GMAT study calendar, build in a review session once per week, and just redo old problems you’ve already tried. During this review session, go back to the Sentence Correction problems you’ve reviewed that week, and try them with a timer one more time. If you get them right this time and you’ve learned everything there is to learn from the problem, you can set them aside for now! If you miss a problem when you redo it in a week or two, though, you may have a weak area that needs some extra time and attention.

FROM Manhattan GMAT Blog: 2019–2020 MBA Essay Analysis: INSEAD, UCLA Anderson, UVA Darden |
How can you write essays that grab the attention of MBA admissions committees? With these thorough essay analyses, our friends at mbaMission help you conceptualize your essay ideas and understand how to execute, so that your experiences truly stand out. This week, we round up essay analyses for INSEAD, the UCLA Anderson School of Management, and the University of Virginia’s Darden School. INSEAD ESSAY ANALYSIS 2019-2020 We noted no adjustments in INSEAD’s MBA application essay prompts this year. This season’s candidates must respond to four short career-focused queries and provide three motivation essays that together total 1,200 words. Applicants are also tasked with completing a video component for which they answer four questions as four separate video recordings. Given the sheer number of prompts, tasks, and questions involved, some candidates may find INSEAD’s essay gauntlet a bit intimidating, if not outright punishing. Read on for our full analysis of the school’s prompts, which we hope will make the process a little easier to manage. UCLA ANDERSON ESSAY ANALYSIS 2019-2020 The UCLA Anderson School of Management appears to be embracing a kind of “less is more” approach with its application essay prompts this year, having cut its total word count for its essays from 800—which we already considered rather sparse—to just 550. What was previously its first required essay (500 words) about applicants’ short- and long-term professional aspirations and why Anderson is the right school for them has been broken down into two mini-essays (150 words each) that cover essentially the same information but now in a more succinct and direct way. Meanwhile, its 300-word “short answer” question from last year about candidates’ passions has been replaced with a 250-word submission on a characteristic applicants share with Anderson’s student community. Even the school’s reapplicants must contend with a stricter limit on what they can share with the admissions committee, now that that essay has been cut from 750 words to 500. All this minimization might tempt more candidates to consider taking advantage of the school’s optional essay, but Anderson specifies that this submission is for “extenuating circumstances” only, so applicants need to be prudent about doing so. Read on for our full analysis of the school’s essay questions for 2019–2020. UVA DARDEN ESSAY ANALYSIS 2019-2020 After completely reworking its MBA application essay questions last season, the admissions committee at the University of Virginia’s Darden School has done just a little fine-tuning this year. Candidates must still respond to five prompts and do so within a 700-word limit, but a new query has been added, while two previous ones have been combined into a single question. As a whole, the prompts again cover applicants’ personal, educational, and career objectives while touching on aspects of Darden’s particular character and ethos—notably, its learning teams, vast international reach, and (now) diversity. In this analysis, we offer our best essay advice for all of the school’s 2019–2020 questions.

FROM Manhattan GMAT Blog: 2019–2020 MBA Essay Analysis: Carnegie Mellon, Cornell, Emory |
How can you write essays that grab the attention of MBA admissions committees? With these thorough essay analyses, our friends at mbaMission help you conceptualize your essay ideas and understand how to execute, so that your experiences truly stand out. This week, we round up essay analyses for Carnegie Mellon University’s Tepper School of Business, the Samuel Curtis Johnson Graduate School of Management at Cornell University, and Emory University’s Goizueta Business School. CARNEGIE MELLON TEPPER ESSAY ANALYSIS 2019-2020 After switching up its application essay approach last year and offering candidates three prompts from which to choose, Carnegie Mellon University’s Tepper School of Business has reverted back this season to posing just a single essay question that all its applicants must respond to. Candidates have up to 500 words with which to answer the school’s query, up from just 350 before, and must explain what they will bring to the Tepper community that will allow them to make an impact on it. Applicants who feel that this somewhat brief essay is not sufficient to fully convey their candidacy to the admissions committee can take advantage of the optional essay, which is sufficiently broad to accommodate discussions about more than just problem areas in one’s profile (if executed effectively). Here’s our full analysis of Tepper’s essay prompts for 2019–2020. CORNELL JOHNSON ESSAY ANALYSIS 2019-2020 This MBA application season, the Samuel Curtis Johnson Graduate School of Management at Cornell University is tightening up the parameters within which its candidates can share their story with the admissions committee. Although the school has expanded the word limit for its goal statement mini-essay from 250 to 350, it has cut back the allowances for all its other submissions. Each of the written essays (including the optional/reapplicant essay) has been shortened from 500 words to 350, and the video option truncated from five minutes to three. Also, the admissions committee is now requesting just one representative story for its “back of the resume” essay, rather than allowing applicants the leeway to include as many as they wish (or could reasonably fit) in that piece. Clearly, Johnson has little interest in lengthy, highly detailed discussions of its applicants’ candidacies and wants to get right to the heart of the issues it considers most valuable in its evaluations. So if you are ready to deliver the information Johnson is seeking, read on for our full essay analysis of the program’s latest prompts. Download: Before you apply to Cornell Johnson, be sure to check out the following free resources from mbaMission… For a thorough exploration of Johnson’s academic offerings, defining characteristics, crucial statistics, social life, community/environment, and other key facets of the program, please download your free copy of the mbaMission Insider’s Guide to Samuel Curtis Johnson School of Management. EMORY GOIZUETA ESSAY ANALYSIS 2019-2020 Although the content covered in the essay questions for Emory University’s Goizueta Business School has not changed much this season, the school has switched things up a bit by making one of its required submissions a video essay. Thankfully for its applicants, Goizueta not only provides the question(s) for the video in advance but also gives candidates three options from which to select. In their written essays, applicants must discuss their short-term career goals and a past leadership experience, and in the video, they are expected to address either a personal passion, some valuable counsel they once received, or a value they have in common with the school. Candidates may use the Additional Information option to provide clarification or explanation about elements of their candidacy, if necessary, but must do so very succinctly, given the 100-word limitation. On the whole, Goizueta’s essay prompts focus more heavily on applicants’ professional sides, though perhaps the combination of a personal question and the video component is enough to sufficiently round out each candidate’s profile for the admissions committee.

FROM Manhattan GMAT Blog: Analyzing Your GMAT Enhanced Score Report (Part 1) |
After you take your official GMAT, you can order an Enhanced Score Report (ESR) that provides more detailed data about your test performance. If you’re planning to retake the GMAT, the ESR can provide you with a good sense of what you need to improve in order to earn a higher score next time. And you can order the ESR even if you cancel your score—a really helpful feature. First, have you already bought an ESR? If so, go grab it right now. If it has been a while since you downloaded it, go and download a new version from the official website. GMAC periodically releases new features and they’re retroactive—when you download the report again, you’ll get the new features, even if they weren’t available when you first bought the report. If you aren’t sure yet whether you want to buy your Enhanced Score Report, GMAC offers a sample of a full report so that you can see what’s included. (Note: If you are planning to take the exam again and are at all unsure about what you need to improve, I would consider investing in the ESR. It won’t tell you everything you need to improve, but it will provide important information. As of this writing, it costs $30.) What does the GMAT Enhanced Score Report contain? This series will show you how to analyze every data point contained in the report. Let’s start with a quick summary. There are 5 sections in the report; I’ve split the data in each section into two groups: really useful and less useful. (Note: If certain data is repeated—for example, a score—I only mention it the first time the data point appears in the report.) Grab your ESR or GMAC’s sample ESR and scan the report as you look through the below. (Note: The links will take you to the specific section of this three-part article that covers that area in detail.) 1) Overall GMAT Exam Performance Really Useful:

GMAT Enhanced Score Report: Overall GMAT Exam Performance The very first data point is your Total score—the score everyone means when they say “What did you get on the GMAT?” The Total score is a 3-digit score on the scale 200 to 800. You’ll also see a percentile number—that’s the number that has a th right after it. For instance, if you see 90th, then you scored in the 90th percentile. A percentile is a ranking; if you scored in the 90th percentile, then you scored better than 90% of the people who have taken the exam over the past 3 years. After your Total score, you’ll see your section scores and percentile rankings for each of the four sections (IR, Verbal, Quant, and Essay). Your Quant and Verbal scores combine to give you your Total score; the IR and Essay scores are completely independent of everything else. Here’s the scoring info from an exam I took in 2015: Aside: Yes, I “only” scored a 710 even though my top score is 780! We are often testing out various hypotheses when taking the official exam. On this one, I took IR normally. On Verbal, I wanted to see whether I could gauge the kinds of questions that someone capable of scoring a 40 would likely get right or wrong—and, yay, I succeeded in scoring a 40 (I didn’t the first time I tried this). On Quant, I wanted to see what would happen if I bailed immediately every single time I saw a topic I hated (no limits in terms of the number of times I did this). I guessed (B) immediately on 8 questions (this was back when there were 36 questions in the Quant section). Back to our analysis. Most schools care most about your Total score, then Quant and Verbal, then IR, and finally Essay. Here’s how to interpret your scores:
This first page of the report also contains a graphic showing average time spent per problem for each of the three multiple-choice sections (IR, V, Q). I find this data too broad to be very useful, but the timing data later in the report is very valuable. GMAT Enhanced Score Report: Integrated Reasoning Performance Of the data given in this section, I find the timing data the most useful. The percentage correct isn’t all that useful because your score already tells you whether you did well enough or whether you want to do better—and the IR section isn’t adaptive, so doing better on IR really does mean answering more questions correctly next time. One thing to add on scoring: If you want to go into management consulting or banking for “name” firms, aim for a higher IR score. These companies all ask for your test scores when recruiting for internships or post-school jobs. A Bain spokesperson went on record a few years back, saying that they were checking IR scores as well, since that section of the GMAT best mimics the kinds of skills they want their consultants to have. They didn’t say what kind of score they want to see, but I would consider 6 the minimum and I’d be trying to get a 7 or 8. Take a look at this: Notice anything in that timing data? Wow, did I spend way longer getting stuff wrong than right. Of course, I’m more likely to spend more time on hard problems and I’m also more likely to get hard problems wrong. But I apparently didn’t do a very good job of deciding when to bail on this section. I should have had at least a couple of bail-fast / not-worth-my-time problems helping to bring down my average incorrect time. So that’s a lesson learned for next time. (Yes, I still scored an 8 on this section and the percentage correct data indicates that I probably got just one question wrong. But I see this pattern a lot for people who are scoring 4 or 5 and want to pick up a point or two. One of the easiest ways is to stop spending precious time and brain energy on stuff you’re getting wrong anyway. Let it go!) Unfortunately, that’s all we get for IR—there are too few problems given in the section for the report to show any statistically significant data in terms of problem type or content area. GMAT Enhanced Score Report: AWA Section Performance AWA stands for Analytical Writing Assessment—the Essay. As I mentioned earlier, approximately 80% of all test-takers earn a good-enough score on the essay; you only need to worry about this section if you score lower than a 4. If that does occur, then take a look at the sub-section rankings (Analyze, Relevancy, Organization, and Communication). If one or two categories are a lot lower than the others, then you know you need to work on that area. Below the graph, the report gives you a short description of your performance in each category. If you have the main Official Guide book, grab that to gain more insight. Flip to the AWA chapter and find the Scoring Guide. It describes the qualities associated with essays scored 6, 5, 4, 3, 2, 1, and 0. Find the score you received and read the description. (If you received a half-point score, such as 3.5, then read the descriptions for the scores on either side—3 and 4, in this example.) As you read the OG description, pay special attention to anything that sounds like the areas that were ranked lower in your ESR. For example, let’s say that I scored a 3 on the essay and my Relevancy category was the lowest in the ESR. In the report, Relevancy is discussed in terms of how well you supported the main points of your critique. In the OG, one of the bullets for a score of 3 has this to say: “offers support of little relevance and value for points of the critique.” So either I didn’t provide enough support at all or the support I did provide was not relevant or appropriate for whatever point I was trying to make.

FROM Manhattan GMAT Blog: Analyzing Your GMAT Enhanced Score Report (Part 2) |
Last time, we talked about how to analyze the overall exam data of your Enhanced Score Report, as well as the data for the IR and Essay sections. Now, it’s time to dive into the Verbal section data. First, the report will tell you your Sub-Section Rankings—your percentile rankings by question type (Critical Reasoning, Reading Comprehension, Sentence Correction). This is extremely useful because you can tell whether you are significantly stronger in certain areas. If the rankings are within about 10-15 percentile points, I’d consider that statistical “noise.” For example, if CR is 60th percentile and RC is 50th percentile, I don’t think there’s a hugely significant difference in your performance on those two question types. Why? There are too many other variables that go into this data. Standardized tests are not perfectly precise; they have standard deviations for a reason. For example, the test is adapting to you as you go, so you may happen to get harder RCs than CRs, on average. If so, you’re likely to get more RCs wrong—and that may pull down your percentile ranking (depending on how the rankings are calculated for this report). Alternatively, you may happen to get a higher proportion of questions in your areas of weakness for one question type; that would also pull down your percentile ranking for that type. Here’s the beginning of the Verbal data for my 710 exam: The Score text in blue is something that I added to the image—I looked these up on the mba.com page that shows all the GMAT percentile rankings for scores. I need to marry that data with my timing data in order to interpret this. In the report, just after the above rankings chart, another chart shows that I averaged 1:25 on CR, 1:14 on RC, and 1:39 on SC. How do you think I should interpret the percentile and timing information together? No really, think about it before you keep reading. La la la. Don’t look below yet. Okay, here’s what I think. I spent extra time on SC (we’re supposed to average about 1:20), so that matches up with me doing so well on those. And I was going faster than average on CR, as well (1:25 vs. the standard average of 2:00). So this reinforces the idea that I’m probably about equal in SC and CR. But I was going really fast on RC. That 1:14 includes my reading time! It looks like I was rushing RC, and rushing usually leads to careless mistakes—so maybe my RC isn’t as bad as it looks from the percentile ranking. I might do better if I stop rushing things. If both CR and SC had been longer than average, or if one had been much longer than average, then I’d need to figure out what trade-offs are worth my time. It may be the case that I want to do exactly what I did and I’m willing to sacrifice RC—maybe I already know that RC is the worst question type for me. But if I’m doing this unconsciously, then there’s a good chance that I’m sacrificing something that would be easier to get right. (On quant, in particular, I see this pattern all the time: People spend more time on Problem Solving and sacrifice Data Sufficiency as a result—when they could actually do better on DS than PS if they spent normal time on DS.) GMAT Enhanced Score Report: Verbal Performance by Fundamental Skills This section shows your percentage correct for each question type across two sub-categories for that type:
The ESR has a FAQ section explaining each category (click on the FAQ tab at that link). For RC, the distinction seems pretty clear: inference vs. stuff that was explicitly stated in the passage. For SC, I’m pretty sure that the two categories are, broadly speaking, grammar and meaning. That’s a good split—but it’s also true that sometimes the line is fuzzy (you can call the same thing a grammar issue or meaning issue). Since I don’t know exactly where they draw the line, I’m not 100% sure how to act on this data. For CR, the descriptions are a little too general—I feel like I’m doing what they describe on every CR problem. So I just ignore that one entirely and move to the next set of (very useful!) data points. GMAT Enhanced Score Report: Performance Progression Before I tell you what I think, examine the data below and figure out what you think. There are three charts: Percent Correct, Average Difficulty, and Time Management, each by quadrant (or quarter) of the section. Thoughts? (You might have noticed that this isn’t from my test. My data wasn’t very useful for this particular analysis because I wasn’t taking the test normally.) First, I have to give a caveat: Each chart shows four data points, representing approximately one quarter of the test, but the exam is question-adaptive (that is, it adapts after every question you answer), so it’s a challenge to interpret this data. I understand why GMAC doesn’t give us more granular data (it would give away too much information about how the algorithm works)—but we do have to be careful with how we analyze this. Second, both for that reason and because this is an adaptive test, it’s crucial to analyze this data all together. Any one chart in isolation doesn’t tell you that much. Finally, let’s call this test-taker Zee. The test starts you somewhere in the medium range. Since Zee scored a 37 on Verbal, the test started at a lower level than Zee’s level—so for the first quadrant of the test, Zee’s score went up. You can see that by combining the first two charts—Zee had a good percentage correct and the average difficulty increased from quadrant 1 to 2. Zee even accomplished this while staying just under the average time. Most of the time, my student’s ESRs will show extra time spent during one or more of the earlier quadrants (remember that for later). The percent correct for the second quadrant was still on the higher side, but the average difficulty dipped in the third quadrant. So it’s likely that somewhere in the second quadrant (probably later in the quadrant), Zee started struggling more (as everyone does on this test, since it’s adaptive). This is where the limitation of having only 4 data points comes in…we have to guess when stuff happened. And then Zee hit a wall in the third quadrant. And look at the time management pie for the third quadrant—on average Zee was spending a lot more time on the incorrect problems. So basically, Zee started getting really hard problems and tossing a lot of time at them. Not surprisingly, Zee got these really hard problems wrong anyway—and then had to rush on others to get back on time. (If Zee were my student, I’d be recommending our Yellow Pad time management technique right about now.) Sometimes Zee got some of those really-fast problems right, but there may have been some careless mistakes in there as well contributing to that 57% incorrect in quadrant 3. It looks like Zee might have dropped down even further than Zee is really capable of scoring, because that fourth quadrant was really good—almost everything right and the difficulty increased again. I wonder whether Zee could have lifted even further but just ran out of problems / room to improve (because the section ended). So there’s an opportunity here for Zee to learn how to identify really hard problems and let them go faster. Zee can then use that time on other problems that Zee has a better chance to answer correctly. If so, then Zee’s score won’t drop as much in the third quadrant, and Zee will be able to lift the score even further by the end of the section. Speaking of the end of the section: The GMAT is a Where You End Is What You Get test—so if you tank the fourth quadrant because you’re running out of time (or for any reason!), your score is going to drop and then…that’s it. That’s your score. Remember when I said that I’ll usually see a similar trajectory to Zee’s at the start, but with a higher average time for the first quadrant or two? When that happens, the test-taker has to make up that time somewhere else—and that somewhere else is usually the fourth quadrant. The ESR will show a really fast average time and a really low percent correct for quadrant 4—basically, your score is tanking in the fourth quadrant because you’re running out of time. And Where You End Is What You Get. If you analyze these three charts together, you can get a sense of your scoring trajectory through the section—and this is super valuable for your retake. If you haven’t (yet!) gotten the score you wanted, then it’s almost certainly the case that you need to get better at how you take the test. That includes decisions that you make about when and how to spend your time and mental energy in order to put yourself in the best position to finish the section strongly. One more thing: When people hear that the GMAT is a Where You End Is What You Get test, they ask whether they should purposely just guess really quickly for the first third of the exam and then spend all of their time on the final two-thirds. You don’t want to do that either—that’s the equivalent of having the test start you at 0 instead of halfway up the difficulty axis, so now you have a lot further to lift (and you only have two-thirds of the questions left to help you lift). What you really want is a steady trajectory across the whole section. If you’re doing well, you will earn really hard questions—ones that are too hard for you. You want that to happen! And then you want to recognize that they’re too hard and let go—that is, you want to maximize your ROI on this exam.

FROM Manhattan GMAT Blog: 2019–2020 MBA Essay Analysis: Georgetown, London Business School, Oxford |
How can you write essays that grab the attention of MBA admissions committees? With these thorough essay analyses, our friends at mbaMission help you conceptualize your essay ideas and understand how to execute, so that your experiences truly stand out. This week, we round up essay analyses for Georgetown University’s McDonough School of Business, London Business School, and the Saïd Business School at the University of Oxford. GEORGETOWN MCDONOUGH ESSAY ANALYSIS 2019-2020 Georgetown University’s McDonough School of Business has made some substantial changes to its application essay questions this year, broadening candidates’ opportunity to present their strongest qualities to the admissions committee for evaluation. Applicants must still provide one 500-word written essay but now get to choose from three question options. Rather than being strictly required to discuss a single defining moment, they can write about leading outside of their comfort zone, a failure-as-learning-opportunity situation, or their personal connection with the brand of someone they admire. The school’s video essay remains unchanged and allows candidates to creatively showcase their individuality and personality. Finally, although the school offers only one optional essay this season, rather than two, the prompt gives candidates the leeway to discuss anything they feel is necessary, so it should be sufficient to meet everyone’s needs. Our full essay analysis offers ideas and advice for addressing all the school’s prompts. LONDON BUSINESS SCHOOL ESSAY ANALYSIS 2019-2020 Once again, London Business School (LBS) appears to be satisfied with the scope and presentation of its application essay questions, having made no modifications to them this season. Although the program strictly requires only one essay—one that largely constitutes a traditional personal statement—some applicants may want to seriously consider submitting the optional essay as well if they feel that doing so will facilitate a fairer or more thorough evaluation of their candidacy. In our analysis, we offer our advice on crafting your approach, whether you ultimately write just one essay for LBS or two. Download: Before you apply to London Business School, be sure to check out the following free resources from mbaMission… For a thorough exploration of London Business School’s academic offerings, defining characteristics, and other key facets of the program, please download your free copy of the mbaMission London Business School Program Guide.

Many MBA candidates find admissions interviews stressful and intimidating, but mastering this important element of the application process is definitely possible—the key is informed preparation. And, on your way to this high level of preparation, we offer our free Interview Primers to spur you along. OXFORD SAÏD ANALYSIS 2019-2020 Over the years, we have seen the top business schools slowly scaling back the length—and in some cases, the scope—of their required application essays, but the Saïd Business School at the University of Oxford may be setting a new record of sorts with its minimalist approach this season. The program is now requiring applicants to provide just a single essay with their application materials rather than two, as it did last year, and one of only 250 words, at that. On the plus side, perhaps, the prompt gives candidates the leeway to share whatever additional information they believe the admissions committee should have in evaluating them, so they are not restricted by a specific topic. Click here for our guidance on approaching Oxford Saïd’s single essay question for 2019–2020, as well as its essays for 1+1 MBA candidates and reapplicants.

FROM Manhattan GMAT Blog: Analyzing Your GMAT Enhanced Score Report (Part 3) |
Welcome to part 3! In the first installment, we talked about the overall Enhanced Score Report, how to interpret your scores, and how to analyze the data from the IR and Essay sections. In the second installment, we talked about how to analyze your Verbal data. Now, it’s time for Quant! Here’s the first page of the Quant section of a GMAT Enhanced Score Report (as with Verbal, not my own report because my data was atypical): What jumps out at you as worth analyzing? This test-taker did much better at Data Sufficiency than at Problem Solving, even though the average time for DS was lower than for PS. What does that mean? First, it means that the test-taker should be quicker to bail on some PS problems. They’re costing more time but not actually providing a better return—it’s wiser to spend extra time on DS, not PS, given the data. Second, the fact that the test-taker is better at DS than PS tells me that she understands math rules and concepts pretty well but is struggling more with actual calculations and solving to the end (which is what we have to do on PS but not DS). So she needs to practice more “math on paper” but she also probably needs to practice alternative strategies that let her avoid that kind of computation, such as estimation and logicking it out. (We have an entire chapter called Logic It Out in our All the Quant guide. If you told me I couldn’t logic stuff out or estimate any longer on the GMAT, I’d refuse to take it again! ) The student was much better at Algebra / Geometry than at Arithmetic. Likewise, the student will want to be faster to bail on pure Arithmetic questions that she finds too complicated—she might as well reallocate that time to Alg / Geo, since she’s better at those areas. Speaking of “those areas,” wouldn’t it be nice if they gave us more detail on our content strengths and weaknesses? GMAT Enhanced Score Report: Quant Performance by Fundamental Skills They do! Take a look: Geometry is awesome! But ouch, Counting / Sets / Series is…not. The FAQ section of the ESR tells you what falls in each of these areas. Here’s what it says about Counting, Sets, and Series (indented material copyright GMAC): Counting (Combinatorics) Problems whose primary focus involves basic combinatorial ideas, such as permutations, combinations, counting paths in a grid, etc. Estimation Problems whose primary focus involves one or more numerical estimations. Series And Sequences Problems whose primary focus involves a numerical sequence (a finite or infinite list of numbers) or a numerical series (the sum of a numerical series), such as arithmetic sequences, geometric sequences, sequences defined by recursion, etc. Sets Problems whose primary focus involves the understanding of, and application of basic ideas about sets, such as their union and their intersection. Problems that appear to be best solved by the use of a venn diagram are considered sets problems.” Okay, we have some good material to work with here. Check it out! Estimation is on this list. That confirms our earlier hypothesis that the student needs to work on this. (I promise I hadn’t already seen this when I made that hypothesis! I’ve literally been writing all of this as I examine the score reports.) Next, the other three areas are pretty annoying quant areas. There are ways for the test writers to ask easier questions in these areas, and so we do want to know how to handle those. But these can also get quite hard. Since this test-taker now knows these areas are weaker, she can just put “harder combinatorics, series / sequences, and sets” on her “bail fast” list. (How do you know which problems are officially rated harder while taking the exam? You don’t. “Harder” means “harder for me.” If it looks annoying and it’s your area of weakness, bail.) It looks like this test taker also needs some work on Value / Order / Factors (and that goes along with the data that she’s struggling more with Arithmetic, by the way). So she would also read the description for these areas and now she’s got a good idea of what she can do to try to improve her score for next time. (Of course, you’ll want to review all topics, even your strengths, before you take the test again.) GMAT Enhanced Score Report: Performance By Quadrant Next up, we’ve got the quadrant data. What do you spot here? As with the Verbal report, analyze all of this data collectively. The quadrant 4 percent correct stat is an immediately obvious one—0% right. Before that, this student was doing really well. What happened? Take a look at the timing data. Yes, the student did very well in the first three quadrants, but she had to burn through a lot of extra time to maintain that performance. Then she had to rush a lot in the fourth quadrant, so it’s no surprise that her performance dropped so much. The great news? She still scored a 45 in this section despite dropping so much in the last quadrant. The GMAT is a Where You End Is What You Get test: Your scoring level at the end of the section is your final score. So if she can make some better decisions earlier in the section—which will definitely involve using our Yellow Pad time management technique and choosing a small number of problems on which to bail fast—then she won’t miss a bunch of questions and have her score drop at the end. And that means she’s got a really good chance to score in the high 40s (if not higher!) on her next official test. Remember our earlier takeaway about finding other quicker, dirtier ways to do math, including estimation? Getting better at that will also help her to manage her time on the test. All in all, this student has quite a bit of opportunity to lift her score. One last thing. It’s sometimes the case that certain data points don’t seem to be as useful (for example, if your percent correct was about the same for all content areas) but even “low-contrast” data points tell you something (for example, that you have a solid foundation across all content areas—a good thing to know!). If you’re planning to take the test again and you don’t think that you already know what you need to improve, then the ESR can be a valuable tool, even with its $30 price tag. That’s it! We’ve analyzed the entire Enhanced Score Report. Happy studying! Don’t forget that you can attend the first session of any of our online or in-person GMAT courses absolutely free. We’re not kidding!

FROM Manhattan GMAT Blog: How to Get a (Nearly) Perfect Score on the GMAT |
Reports vary about how many perfect 800’s are achieved each year, but out of 200,000 people taking the GMAT each year, we think there are somewhere between zero and 30 perfect scores. You have a better chance of being hit by lightning as you’re winning a Powerball lottery! (That’s not true, but calculating the probability of getting hit by lightning as you’re winning the Powerball does sound like an 800-level GMAT probability problem). There were ZERO scores of 800 in last year’s crop of students admitted to Harvard, Wharton, Stanford, etc. Keep reading for why it’s (nearly) impossible to get a perfect score on the GMAT and for strategies for getting a score in the 99th percentile. What is a perfect score on the GMAT? 800. Two other scores come with a GMAT, besides the 200-800 score: Essay (0 – 6) and Integrated Reasoning (1 – 8). So if you’re looking for full-on “I pitched a perfect game / I summited Everest without oxygen tanks”, it would look like 800, 6 on Essay, 8 on Integrated Reasoning. I’m not sure if anyone has actually achieved this clean sheet, but anyone who has the capacity to get an 800 should be able to bang out a top Essay and IR score, as getting 6’s and 8’s, respectively, is very common. How do you get a perfect score on the GMAT? GMAT scores are on a scale from 200 to 800. This score is derived by combining a Quant and a Verbal subscore, each on a scale from 6-51. The Quant and Verbal sections each involve a little over 30 questions in a little over 60 minutes. To get an 800, you would need a perfect 51 on Quant and Verbal. The specific math by which your Quant and Verbal subscores are translated into your overall 200-800 GMAT score is a proprietary GMAC secret, kept in a secure bunker deep in the Earth’s mantle, along with the formula for Coca-Cola Classic and Colonel Sanders’ secret blend of herbs and spices for KFC chicken. How much do business schools care about whether you get a perfect score on the GMAT? Not at all. No b-school admissions office is expecting to see any perfect scores slide across their desks. As mentioned earlier, there were no scores of 800 in last year’s crop of students admitted to top schools. It is also suspected that the vast majority of people who do get 800’s are just sad, overly familiar “students” like me, who teach GMAT. Can GMAT teachers easily get a perfect score on the GMAT? Not at all. In fact, our company pays teachers way more than other companies do for the sole purpose of attracting the best and brightest talent. Despite all that, I know of only one teacher in our company history who had an 800. He also had a brain-altering injury as an adolescent that gave him some cool savant mental powers. (That is true). The 99th percentile, our minimum cutoff for teachers, starts at 760. The difference between 760, 770, 780, 790, and 800 is basically splitting hairs. It would represent one or two guesses on really tricky Verbal questions landing the right or wrong way. We are pretty capable of getting 51’s on Quant, but getting 51’s on Verbal is almost unheard of. I first took the GMAT ten years ago; I barely studied for it, because I was already teaching SAT and LSAT, and got a 780. Last year, I took the GMAT again. In my arrogant heart of hearts, I thought I was probably contending for one of those mythical 800’s. After all, I’ve been teaching GMAT for a decade now. I have an encyclopedia of problems in my head. This test lives in my gut like a tapeworm. How did I do? (Drumroll, please: …………………!) 770. What the heck? Ten years of becoming a master of GMAT’s content had made me 10 points worse? Of course not. It’s just very volatile as you approach the extremes of the scoring range. As I said before, a couple unlucky vs. lucky guesses can affect your score by 20-40 points. How come (almost) nobody gets a perfect score on the GMAT? The GMAT is not a test that requires or even really allows for perfection. It is an adaptive test, deciding on our next question based on a calculation of our performance up to that point on the test. So, when we get a question correct, the next question is usually harder. When we get a question incorrect, the next question is usually easier. This essentially guarantees that no one can ace the GMAT. Since the adaptive algorithm can continually increase the difficulty level, it can always outpace what we are able to figure out and correctly solve within our allotted average of two mins per question. The reason for making a test of this sort is because what GMAC really wants to measure is not our proficiency at 6th – 10th grade math concepts. It wants to measure our ability to manage ourselves, to make decisions based on priorities, and to invest our scarce resources wisely. We call this “Executive Reasoning”. If we had enough time to fully think through all the problems on a GMAT, then it would only be a test of whether we know the content on the test. Since they really want to test the intangibles, they need a test that guarantees people do not have enough time to think fully through each problem. This forces us into the mindset of an investor. Investors don’t have infinite resources; they can’t fully invest in every opportunity. On the GMAT, since you don’t have enough time to do all the problems in a section (and you can never go back to revisit a problem), then you have to make best guesses in real-time about what is a worthwhile high percentage investment of time versus what would be too much of a longshot. This also forces us to be coldly judicious about bailing from a problem when our initial investment of time isn’t panning out. GMAC wants to punish stubbornness, to enact some penalty for foolishly throwing “good money after bad”. They want to reward humility, realism, and an investing disposition that thinks, “Welp – can’t win ‘em all. That one seemed like a good idea at the time, but I should cut my losses and move on to greener pastures.” We have to stay budget-conscious, so we follow pacing plans as we take Quant and Verbal sections. The test assesses bigger penalties for missing easier questions than for harder questions. And there is a huge penalty for failing to finish all the questions in a section. Most people’s initial trials at a GMAT test involve overspending time on early questions and therefore missing a bunch of doable questions on the backend of the section because they’ve run out of time. So, what should I be shooting for, if it’s not possible for me to get a perfect score on the GMAT? If you’re targeting top 15 schools, you would love to have at least a 720. Being lower than that does not disqualify you, but it puts more of a burden on your work experience and life history to carry your app through. Luckily for us, business school admissions are relatively holistic. Having a less than sparkly GMAT score can be offset by having other attractive features. Sparkly GMAT scores are often needed to compensate for a lack somewhere else in your application. For example, if you are applying to a rigorous finance program, but your undergrad was in Political Science and you’ve been working in marketing ever since, then you need to be able to convince the admissions board that you handle top shelf math. A great GMAT score, with a good 45+ quant subscore, will do just that. How long do I need to study in order to (nearly) get a perfect score on the GMAT? This answer would vary a lot, depending on the person, but I find it hard to believe anyone could score in the 99th percentile without at least 2 months of studying (unless you already teach SAT and LSAT). I think it’s much more realistic that you would need closer to 6 months of studying. Let’s break down some of the challenges:

FROM Manhattan GMAT Blog: How to Review a GMAT Critical Reasoning Problem |
Are you keeping an error log for your GMAT Verbal practice? If your goal is to get a certain overall score on the GMAT (say, a 700), don’t underestimate the value of Verbal. That’s true even if you’re scoring at a higher percentile in Verbal than you are in Quant. At first, you may find that tough Verbal problems—especially Critical Reasoning and Reading Comp—seem arbitrary and subjective. But, they’re less subjective than they seem. GMAT Verbal problems all go through an experimental stage, where they aren’t counted towards your score. A problem is only used on the real GMAT if, during that experimental stage, high scorers consistently get it right and low scorers consistently get it wrong. That tells us that there’s a method to the madness. High scorers are people who have figured out what makes a right answer right. And the way you get there is by reviewing Verbal just as carefully as you review Quant. Reviewing Critical Reasoning You should review most of the Critical Reasoning problems you do, even if you get them right. That’s because Critical Reasoning arguments use the same structures over and over, even though the content changes. The wrong answers also use the same traps repeatedly. If you get a problem right, analyze the wrong answers anyways. You might see very similar ones in a harder problem on test day. The only problems you shouldn’t review (yet) are the ones that were unrealistically hard. Feel free to set those aside for later in your studies. Your time is best spent on the problems that will pay off most quickly. Redoing a Critical Reasoning Problem The first step of reviewing a CR problem is redoing it. Do this shortly after finishing a problem set, or during your next study session. When you redo a CR problem, you don’t need to use a timer. You’re also welcome to look back at the notes you took (if any) when you first did the problem. When you try the problem a second time, with a clear head, three things can happen:
Instead, just check what the right answer was. Try to come up with your own theories for why that answer was right, and for why the other answers were wrong. Then, you can read the explanation—to prove or disprove your own theories, or to add to them. If you can’t get anywhere at all with a CR problem unless you read the explanation, the problem might just be too hard to do at the moment. Or, you might need to review how to approach that type of CR problem (for instance, by using GMAT Interact) before doing more practice questions. Breaking down a Critical Reasoning problem Let’s assume that you’ve tried the problem twice, and you now know what the right answer is and why it was right. You’re ready to learn. Before you keep reading, do this CR problem from GMATPrep. Use a 2-minute timer. Then, take a break for a couple of minutes, and try it again. Correctly measuring the productivity of service workers is complex. Consider, for example, postal workers: they are often said to be more productive if more letters are delivered per postal worker. But is this really true? What if more letters are lost or delayed per worker at the same time that more are delivered? The objection implied above to the productivity measure described is based on doubts about the truth of which of the following statements?
Here’s what your review process will look like for a CR problem. There are four pieces of a CR problem, and you can take notes on any of them, depending on what was interesting about the problem.
Student A: based on = assumption Student B: if the question is complicated, focus on one piece at a time. “The objection to the measure” = letters might be delayed, so more letters doesn’t = more productivity. “Based on” = assumption required for this to be true. “Doubt about…” = the right answer will be negative, something that the person objecting DOESN’T believe. Your notes might look like either example, or, if nothing about the question confused or surprised you, you might take no notes at all. If you struggled to understand the argument, or if you picked the wrong answer because you misunderstood the argument, spend some time breaking it down carefully in your notes. You can also think about what answers you could have predicted, based on the argument itself. If you notice any patterns in the argument—for example, if the argument looked like a “tell me why” argument—you could note that as well. The most important part of reviewing a CR problem, however, is understanding the answer choices. Reviewing Critical Reasoning answer choices A lot of the time, two or three of the answer choices in a CR problem will be easier to eliminate than the others. If your CR problem is like this, take a moment to make sure you do understand why those answer choices were wrong. The ones to really dive into, though, are the answer choices that weren’t obvious. If you got the CR question right, make sure you can answer these questions:
Here are some examples of notes from students who missed the problem we worked on earlier: Student A picked (E):
If there are other things you want to remember about a CR problem, edit your error log to include them! For instance, some of my students have used an extra column in their error log to write down how much time they spent on a problem, so they could go back and only redo the problems that took them too much time. Or you may want to take a note whenever you fall for a trap answer, so you avoid falling for the same ones over and over. A “general takeaways” column can also be useful! Finishing up Now that you’ve redone the problem, understood the solution, and reflected on your own process, put the problem aside for a week or two. On your GMAT study calendar, schedule a couple of hours every other week to do nothing but redo old problems from your log. It doesn’t even matter whether you remember the right answer when you redo: all you’re doing is reminding your brain of the problem and the lessons you learned from it. You should also quickly read over your problem log at least once a week, maybe when you have a few minutes of spare time but not enough time for a full study session. There’s no need to redo any problems or take any more notes unless you want to! Just glance at your takeaways to keep them fresh in your mind. The secret to mastering Critical Reasoning is to get methodical. Understand the rules behind each problem type, and what they look like when they’re used in problems. Doing a lot of practice problems will expose you to these rules, but review is the way to truly understand them.

FROM Manhattan GMAT Blog: How to Review a GMAT Reading Comprehension Question |
Reviewing a GMAT Reading Comprehension question is similar to reviewing a Critical Reasoning problem. Just as with Critical Reasoning, not all RC problems are equally important to review. The most important problems to add to your ‘review later’ list are the ones that were just a bit too hard. Feel free to set aside the 800-level problems for now, but spend some extra time on the ones you almost got right. That’s where you’ll learn the most right now. Whenever you finish a set of GMAT Reading Comp practice questions, set them aside for a few minutes (or a day), then look over them again. Ideally, do this before you’ve even checked your answers: not knowing the right answer immediately will force you to deeply consider all of the answer choices. Start your review by just doing the problem again. Take as much or as little time as you want. If you’re reviewing a tough Detail question, you can also go back and highlight or underline details in the passage. You might end up changing your mind about the answer, or you might end up convincing yourself that your original answer was right. You may also end up unsure about the right answer, even once you spend more time with the problem. In that case, check the right answer first, before you read the explanation. See if you can come up with a theory, before you read the explanation, for why that answer was right. Once you’ve looked over the question a second time, it’s time to decide what you want to remember. You won’t see that exact problem on the test, but the GMAT uses the same types of passages, questions, right answers, and wrong answers across many problems. Here’s how to take notes in a way that will help you approach similar problems on test day. Taking Review Notes on a GMAT Reading Comp Question The majority of GMAT Reading Comp questions can be described as either general or specific. General questions might ask you about the main idea or the purpose of an entire passage, or perhaps about a paragraph or two within the passage. Getting these right relies on doing a few things successfully:
The right answer to a general question is right because, according to the GMAT, it correctly summarizes the main points. Once you know the right answer to a question you’re reviewing, locate those main points in the passage, and note how the details in the passage support those points. Each time you do this, you may learn something new about how to spot the main idea while reading a passage. If anything stands out to you on reviewing the passage, take some quick notes. Here are some examples of what your notes could look like, depending on the passage and the specific problem:
Each time you make yourself think (and take notes) about why a wrong answer is wrong, you’re learning to recognize and avoid that type of wrong answer. Even if you didn’t fall for it this time, you’ll still be better prepared on test day. Here are some common reasons to eliminate an answer while doing a general Reading Comp problem:
Detail questions on the GMAT all have something in common, whether they ask you to identify something that the passage says, or something that the passage only implies. Either way, the right answer must be a statement you can prove by only using information from the passage. In the case of a Detail question, the right answer should be more or less written in the passage somewhere. When reviewing, your first job is to hunt down the “proof” for the right answer. If there’s anything surprising about the proof or how it relates to the right answer, write that in your notes! Did you miss it or misinterpret it? If so, how and why? Knowing what caused you to eliminate a correct answer erroneously will help you refine your own process. Then, look at the wrong answers. Be able to explain why each one is wrong. If any of them were remarkable or surprising to you, especially if you picked one of those, take some notes. Many Reading Comp questions have wrong answers that are wrong for predictable, consistent reasons. (For instance, it’s very common for there to be a wrong answer that uses language similar to that used in the passage, but that has the opposite meaning from the passage itself.) Jot down anything you learned about why an answer might be wrong. If you got the question wrong, figure out two things: what drew you to that particular wrong answer, and what kept you from picking the right answer. This might be something as simple as a misreading (or even not reading that answer choice at all!). But, it could also teach you something about the types of mistakes you tend to make. Anything you learn, write it down for later review. Long-term Reading Comp Review Now you’ve completed a set of Reading Comp questions and you’ve achieved a full understanding of how to read each passage and answer each question. You have some notes written down about what made the right answers right, what made the wrong answers wrong, and how to avoid mistakes next time. Here’s the next step. A couple of times per week, simply glance over your whole problem log, containing all of your notes on RC problems you’ve done in the past. Do this when you have a few minutes of spare time. There’s no need to redo the problems when you do this. All you’re doing is re-exposing yourself to the notes you’ve taken and taking note of any patterns that stand out, and maybe thinking about which problems you’d most like to redo next. Once a week (if you’re focusing heavily on RC), or just occasionally (if RC is less of a priority), go back into your problem log and actually redo the problems you’ve reviewed. Use a timer, and avoid looking at the answer immediately. Did you get them right the second time? That’s strong evidence that you’ve internalized the lessons from those problems. Did you miss them again? That’s data as well: you now know that you should do some more problems of that same type, or revisit the corresponding chapter(s) in the All the Verbal guide.

FROM Manhattan GMAT Blog: 2019–2020 MBA Essay Analysis: Texas McCombs, Fisher College, UNC Kenan-Flagler |
How can you write essays that grab the attention of MBA admissions committees? With these thorough essay analyses, our friends atmbaMission help you conceptualize your essay ideas and understand how to execute so that your experiences truly stand out. This week, we round up essay analyses for the McCombs School of Business at the University of Texas at Austin, the Fisher College of Business at The Ohio State University, and the University of North Carolina at Chapel Hill’s Kenan-Flagler Business School. TEXAS MCCOMBS ESSAY ANALYSIS 2019-2020 Once again, the McCombs School of Business at the University of Texas at Austin has made only slight modifications to its MBA application essay prompts, simply refining the queries without changing the fundamental information on which they focus. The school’s required self-introduction essay (or video, for those who prefer that option) has been in play since at least 2013, and its second essay, for which applicants are asked to imagine themselves at graduation and to reflect on their time at McCombs, now specifies that candidates frame their response within the context of their goals, rather than the broader “post-MBA world.” Anyone with a potential problem area or unclear element in their profile can also submit an optional essay to address the issue(s). As a whole, the Texas McCombs essays give applicants ample opportunity to provide meaningful insight into their characters and strengths. Click here our entire analysis of the program’s essay prompts for 2019–2020. FISHER COLLEGE ESSAY ANALYSIS 2019-2020 The Fisher College of Business at The Ohio State University has expanded its application essay questions this year, giving candidates more of an opportunity to discuss their profiles beyond the statistics and other basic data conveyed in the rest of their application. The school’s first required essay is a rather traditional career goals statement for which the maximum word count has been cut back from 750 to 500. Perhaps this reduction was to allow for the addition of a second required essay without adding too much to the amount applicants need to write. For that new second essay, candidates must share a significant achievement from their past and explain how the experience has equipped them to be an additive member of the Fisher MBA community. If needed, a 250-word supplemental essay is also available for candidates with unusual or unclear elements in their profiles. All aspiring Fisher MBAs must complete a video interview soon after submitting their application, and although this is not technically an essay, we offer some tips for addressing it as well in our complete essay analysis. UNC KENAN FLAGLER ANALYSIS 2019-2020 The University of North Carolina at Chapel Hill’s Kenan-Flagler Business School is offering a mix of old and new essay prompts this season, having maintained its rather traditional career-focused first essay while replacing its second required essay question with a trio of new options. Rather than having to discuss a core value they share with the school, applicants can choose the prompt they feel gives them the best opportunity to convey the nonprofessional side of their candidacy. And although the word count has been slashed in half (from 300 to 150), the school’s optional essay still provides candidates with an outlet for explaining a problematic element of their profile or augmenting their application with potentially key information. Our more in-depth analysis of Kenan-Flagler’s 2019–2020 essay questions is available here. mbaMission is the leader in MBA admissions consulting with a full-time and comprehensively trained staff of consultants, all with profound communications and MBA experience. mbaMission has helped thousands of candidates fulfill their dream of attending prominent MBA programs around the world.

FROM Manhattan GMAT Blog: Is Earning a JD/MBA Degree Right for Me? |
[img]https://cdn2.manhattanprep.com/gmat/wp-content/uploads/sites/18/2019/11/mprep-blogimages-wave1-26-e1574348483657.png[/img] Now that you have begun taking steps toward earning your MBA, you may be wondering whether a joint JD/MBA degree could be a good option for you. Or perhaps you have been considering a JD/MBA all along. After two decades of consulting MBA, JD, and joint JD/MBA aspirants, we have learned a few things about this joint degree option, so let us offer some insight into both its utility and some additional factors you may want to consider. A JD/MBA degree can benefit your long-term career by giving you valuable skills and insight that could make you more versatile and effective in your professional role. [list] [*][b]If your ultimate goal is to become a corporate lawyer at a leading firm[/b], your primary commitment during your studies needs to be on the law. Law firms generally tend to be rigid and hierarchical, so you cannot expect to simply switch from a traditional business role to become an associate at a notable firm—this kind of shift is exceedingly rare. Nevertheless, also having an MBA offers certain advantages. For example, if you find yourself working on complicated deal structures, your MBA might enable you to better understand the complexities of certain business issues, such as equity and debt issuances. And in the long term, the extensive leadership skills you would gain from the MBA experience will likely make you a more adept manager of employees and clients, and this in turn could facilitate your rise to partner. [/*] [*][b]If your post-graduate goal is to become a traditional business professional[/b], knowing the law could give you a comparative advantage over your peers and colleagues who do not. For example, if you become a banker or private equity associate and are working on a complex deal, understanding basic employment law or grasping the liabilities that a new entity will take on (or not take on) could help you craft more effective approaches and solutions. Likewise, having a profound legal education could help you add nuance in advising clients.[/*] [/list] However, double the degree means that some of the pros and cons of the graduate school experience are likewise doubled. Here are a few primary ones to consider. [list] [*][b]A larger and more expansive network[/b]: You are probably already very aware that earning an advanced degree automatically makes you part of a broad network of classmates and alumni from your chosen institution. So, imagine that you are accepted to Harvard Business School, immediately joining a network of your approximately 925 classmates, plus all the graduates who have gone before you. Now imagine you also get into Harvard Law School, which connects you with roughly 580 more classmates as well as that school’s alumni. You will no doubt graduate with plenty of accomplished friends who will go on to become successful professionals in organizations around the world. Networks can be extremely valuable at all stages of your career, and having access to literally thousands of additional individuals who will generally be inclined to respond to a call or email from you is even more advantageous. [/*] [*][b]A more substantial financial investment[/b]: Taking the time to pursue an advanced degree involves two primary expenditures—the cost of the program (mainly tuition, but also living and other associated expenses) and the [url=https://www.manhattanprep.com/gmat/blog/is-the-mba-worth-it-go-beyond-roi/]income “lost” during your years out of the workforce[/url] (salary, bonuses, retirement contributions, etc.). By choosing a four-year JD/MBA program over a two-year MBA program, you are essentially doubling the cost of your degree. For example, at the University of Virginia’s (UVA) Darden School of Business, you would need to pay approximately $70K tuition for the first year of your MBA. Then you must pay the UVA Law School tuition of approximately $66K per year for two years. And for your fourth year, you pay one semester of tuition for each school (roughly $68K combined). The additional years needed for the joint degree represent a significant financial investment, not only in tuition ($270K versus $140K) but also in those two extra years without income. However, if you are fully committed to pursuing a joint degree, an accelerated three-year program—such as the one offered by Yale—could offer a “break” of sorts because you could return to the workforce one year sooner. We, of course, advise you to examine the student budgets at each program as you decide which path to take. [/*] [*][b]Double the admissions efforts[/b]: At most institutions with JD/MBA programs, you must apply to—and be accepted by—both the business school and the law school separately. This is the case, for example, at Harvard, Stanford, Columbia, the University of Michigan, Duke University, UVA, and New York University. Fortunately, some other top institutions, including Northwestern University, the University of Pennsylvania, and the University of Chicago, require only one application. Although such an important educational decision should not be determined by how cumbersome the application process is, applying to graduate school can unquestionably be grueling. Studying for and taking the required entrance exam, writing essays, securing recommendations, interviewing, scheduling class visits—doubling all these efforts may be a necessary evil but will certainly not be a lot of fun. That said, some schools will allow you to apply to their JD/MBA program after your first year of MBA studies, which does not exactly eliminate the additional work required but does minimize it slightly, as well as offering a break between processes. [/*] [/list] The decision to pursue any advanced degree is a hefty one, requiring you to consider the potential effect on your long-term career, the entire financial impact, the stress and challenge of the admissions process, and the rigor required to complete the studies. And committing to a JD/MBA program entails additional demands and concerns in all these areas. If you are truly interested in applying to a JD/MBA program, we suggest that you inform yourself thoroughly about this path by speaking to individuals enrolled in such programs as well as the schools’ alumni about every stage of the experience.

FROM Manhattan GMAT Blog: What the Executive Assessment Really Tests |
[url=https://www.manhattanprep.com/gmat/blog/about-executive-assessment/][img]https://cdn2.manhattanprep.com/gmat/wp-content/uploads/sites/18/2019/11/mprep-blogimages-wave1-25-1-e1574349505628.png[/img][/url] [url=https://www.manhattanprep.com/gmat/blog/about-executive-assessment/]The Executive Assessment (EA)[/url] is not a math test. Nor is it a grammar test. Sure, you have to know something (well, a lot of things!) about these topics in order to get a good score. But the Executive Assessment is really testing your executive reasoning skills. The term might be unfamiliar, but you already have—and use—these skills every day. Here are some examples: You are faced with a list of 20 unread emails (or, if your inbox is more like mine, about 80). Which ones do you read first? The oldest ones? The ones from your boss? The ones marked urgent? Are there some that you won’t even click on right now because you know, from the sender’s name or from the subject line, that those emails aren’t very important? (And how did that one spam message get through the filter?) You have a choice between working on Product X or Project Y. Project Y will result in about 5% more revenue to the company, but Project Y will also take 50% longer. Which do you do? These decisions aren’t easy ones (and would likely require more information than I gave). This complex decision making is exactly what a good executive needs to be able to do well—and this is what the test writers and business schools actually care about. The math and grammar are primarily used as tools to allow the exam writers to test you on your decision-making ability. [b]How does that help me take the Executive Assessment?[/b] They don’t expect you to get everything right, any more than a CEO expects to clear everything in his or her inbox today. You have to prioritize. A great decision-maker has both expertise and experience: She’s thought about how to make various kinds of decisions, and she’s actually practiced and refined these decision-making processes. While the clock is ticking, she doesn’t hesitate to make a decision and move forward, knowing that she’s going to be leaving some opportunities behind. In order to do that successfully in the business world, you need to know the company’s goals and objectives, and you have to have a good idea of the kind of impact that various tasks or activities will have on the company. You also have to have a lot of practice in making these decisions and observing the outcomes. The same is true for the EA: If you know how it works, and you know what kinds of trade-offs to think about when deciding how to spend your time, then you can learn how to make the best decisions to maximize your score. Your goal, then, is to develop a business mindset for this test. You’re not going “back to school” when you study for the EA. Rather, approach the exam as an extension of your current work—this is a test of your business ability and decision-making skills. The test does include some school subjects in the details of the questions, so you will have to re-learn some actual facts and formulas, but the focus will be on your decision-making skills above all else. [b]How do I develop a business mindset?[/b] At every step of the way, remind yourself that the EA is primarily a decision-making test. Use this knowledge to help you make appropriate business decisions along the way, during both your studies and the test itself. For example, don’t try to learn everything that could possibly be tested. Rather, prepare yourself to get a good-enough score. Learn the material that is most likely to be tested, with some extra emphasis on your strengths and your “medium weaknesses”—i.e., the ones that you have a better chance to turn around. On the flip side, de-prioritize your biggest weaknesses—literally get those kinds of problems wrong faster and spend your precious study and test time elsewhere. Happy studying!

FROM Manhattan GMAT Blog: Common Math Errors on the GMAT |
Do you ever make mistakes on GMAT math that just don’t make sense when you review? That’s not unusual, and in fact, it’s probably one of the most common reasons to miss easy GMAT math problems. Here’s why:
A lot of GMAT math errors are based on memorization. Suppose that you want to simplify the following expression: 0.00004 x 10-3 Quick, which of the following rules is correct?
In this article, I’ll list a handful of mistakes that people often make on GMAT math. Then, I’ll share a self-check you can use to avoid each one. Because everyone is different, some of these mistakes may be easy for you to avoid. For others, you might decide to double-check every single time. 1. Decimals and exponents Let’s go back to the example above. 0.00004 x 10-3 Instead of memorizing which way to move the decimal, think about whether the decimal’s value should become larger or smaller. Ten raised to a negative power, like 10-3, is a fraction. In this case, it’s equal to 1/1,000. Multiplying something by a small fraction will definitely make it smaller. A small decimal has more zeroes in front of it. So, to simplify this expression, you want to add more zeroes in front of the 4. To remember how many zeroes to add, think about dividing by 10. Each time you divide a decimal by 10, you’d add in one zero. Dividing by 103, which is what we’re doing in this problem, is the same as dividing by 10 three times. So, you need to add three zeroes. The right answer is 0.00000004. 2. Decimals and percents When you want to find 0.05% of 13,000, what do you multiply 13,000 by? It’s easy to lose a decimal place or two and end up with an answer that’s off by a factor of 10. Here’s the solution. The literal meaning of the percent symbol is “/100”. In fact, the percent symbol sort of looks like a division sign with two zeroes, symbolizing a 100. Any time you see a math expression including a percent, write it on your paper as if the percent sign said “/100” instead. For this question, you’d write the following on your paper: 0.05/100 x 13,000 This simplifies to 0.05 x 130, or 6.5. You can use this trick even when there are variables involved in the expression. For instance, a question might ask you “If y% of x equals 50, what is x% of y?” Write this as follows: (y/100)(x) = 50 (x/100)(y) = ? In both cases, the left side of the expression simplifies to xy/100. So, they’re equal, and the answer to the question is 50. 3. Variables in fractions Simplifying a fraction that only includes numbers is relatively straightforward, although the math might be tedious. But, when the fraction includes variables, the math gets less obvious. Here’s an example of something you might have on your paper while doing a GMAT math problem: (x + 7y) / (y²) You may have memorized a rule that says “you can cancel common terms from the top and bottom of a fraction.” But that rule comes with some fiddly little caveats, like the fact that you aren’t allowed to do this: (x + 7y) / (y²) (x + 7) / (y) Here’s another way to think about it that’s more reliable. Factor out the same value from both the top and the bottom of the fraction. Then, you can “cancel” (divide) both of those terms. In the example above, you can’t factor a y out of the top of the fraction. So, you aren’t allowed to cancel the y. But, in this example, you can: (y³ + 7y) / (y²) y(y² + 7) / y(y) (y² + 7) / y If you’ve made this mistake before, commit yourself to thinking each time: what am I factoring out of the top and bottom of this fraction? If you can’t factor it out, you don’t get to divide by it! 4. Properties of 0 There are two common Number Properties rules in GMAT math that relate to the number 0. Unfortunately, they’re almost identical to each other, and it’s so easy to get them switched around!
All even numbers have one thing in common: if you divide them by 2, you don’t end up with a fraction or a remainder. For instance, 2,476 is even, because if you divide it by 2, you get a round number with nothing left over. The same is true of, say, -18. This rule of thumb will always accurately tell you whether a number is even. What happens when you divide zero by two? You get zero. 0/2 = 0 Sure enough, there’s no fraction or remainder. So, by our rules, zero is definitely even. Why isn’t zero positive or negative? This is a trickier one, because it depends, in part, on language. In some languages other than English, zero is actually said to be both positive and negative. However, on the GMAT, it’s neither. On the GMAT, a good general strategy is to visualize a number line. Numbers to the left are smaller than numbers to the right. Anything to the left of zero is negative, and anything to the right of zero is positive. And because zero itself is neither to the left nor to the right of zero, it can’t be positive or negative. 5. Dividing by variables How do you solve this equation? 3x = x² The obvious first move is to divide both sides by x, giving you this answer: 3 = x But, that’s actually a big problem. Why? Because x doesn’t necessarily equal 3. In fact, x could also equal 0. (Plug 0 into the equation 3x = x², and it works out just fine!) You could memorize a rule: “equations that have the same variable in every term also have 0 as a solution, on top of whatever solution you come up with.” But, here are two alternatives.
x² – 3x = 0 x(x – 3) = 0 This gives you two solutions: x = 0, and x = 3. The other alternative is to be extra careful never to divide anything by zero. That includes variables! If a variable might equal zero, then you still can’t divide by it. After all, you might be dividing by zero without realizing it. The right approach is the same one as shown above: instead of dividing out an x (don’t do it, since it might equal zero!), focus on factoring it out without dividing. To do that, put both terms on the same side of the equation, then factor out the x that they have in common. 6. Dividing by variables, with a twist There’s one other situation where it’s dangerous to divide by a variable: when you’re simplifying an inequality. This causes even bigger problems than the ones shown above. For example, suppose you’re trying to simplify this inequality: 3x If you just divide by x, you get this: 3 That’s perfect, except that it’s the wrong answer. x definitely doesn’t have to be bigger than 3! For instance, x could be -1: 3(-1) = -3 (-1)2 = 1 -3 You may already know a rule about dividing inequalities: if you divide or multiply an inequality by a negative number, you have to flip the sign. That causes more problems when you’re dividing or multiplying by a variable. You don’t know the value of the variable, so you don’t know whether it’s negative or not! So, maybe you have to flip the sign, or maybe you don’t. There’s no way to tell. That’s the issue. The solution is to never divide an inequality by a number unless you know for sure whether it’s positive or negative. If you know that x is positive, you can go ahead and do the division above. If you know that x is negative, you can still do the division, you just have to flip the sign! But if you aren’t sure, you can’t divide by x. What can you do instead? It depends on what the overall GMAT problem looks like. On problems like these, it’s often possible to solve more quickly and easily by testing numbers. Or, you can do something similar to the approach from the previous tip: 3x 0 – 3x In other words, x² – 3x is positive. Therefore, x(x-3) is positive. Next, use some Number Properties facts. The product of x and x-3 is only positive if x and x-3 are both positive, or x and x-3 are both negative. That will happen in exactly two situations. If x is greater than 3, then x and x-3 are both positive, so their product is positive. Or, if x is less than 0, then x and x-3 are both negative, so their product is positive. So, the correct answer is this: x 3 7. Negative variables This conversation about positive and negative numbers leads us to our final tip. Quick: is the following number positive or negative? -x Especially in Number Properties problems, which often ask you whether a value is positive or negative, this can trip you up. It’s easy to see the negative sign when you’re working fast and assume that you definitely have a negative number. After all, -2 is negative, so why not -x? However, that’s only true if x itself is positive. If x is negative, then the number above is actually positive. For instance, if x = -5, then -x = 5. To avoid mistakes, imagine putting individual variables inside of parentheses. -x is really -(x). Therefore, if x = -5, then -x = -(x) = -(-5) = 5. After all, two negatives make a positive. This can also help you remember what to do when you raise a variable to a power. x² really equals (x)², so if x = -5, then x² = (-5)² = 25. Just don’t accidentally include anything else inside of the parentheses! If you do this, you’ll be able to simplify expressions including negative variables correctly.

[img]https://cdn2.manhattanprep.com/gmat/wp-content/uploads/sites/18/2019/12/mprep-blogimages-wave1-39-e1575494245444.png[/img] Here are a few of the most useful quick GMAT math tricks I’ve learned over the years. They won’t show up on every problem, or even on every Quant section. But, if you happen to use one of these GMAT math hacks on test day, it could save you anywhere from a few seconds to a few minutes. [b]Number Properties[/b] [list] [*]The product of two consecutive integers is always divisible by two, the product of three consecutive integers is always divisible by three, and so on. [/*] [*]To check whether a complicated expression is even or odd, plug in 0 and 1. For instance, try the expression 2x3 + x2 + x. If you plug in 0, you get 0, which is even. If you plug in 1, you get 4, which is also even. So, this expression is always even. [/*] [*]If you want to find all of the factors of a number by guessing and testing, you can stop when you reach the square root of that number. For instance, if you’re finding all of the factors of 228, you can stop checking numbers when you hit 15, since that’s approximately the square root of 228. [/*] [/list] [b]Geometry[/b] [list] [*]If you double the side length of a shape (such as a square or triangle), its area quadruples. If you halve the side length, its area is quartered. [/*] [*]Learn the [url=https://www.manhattanprep.com/gre/blog/gre-geometry-three-ways-to-spot-similar-triangles/]three ways to spot similar triangles[/url], so you’ll instantly recognize that two triangles are similar without having to prove it from scratch. [/*] [*]If a problem tells you a shape is a rectangle, don’t forget that the shape could be a square! In fact, a square is often a good case to test on [url=https://www.manhattanprep.com/gmat/blog/how-to-review-a-data-sufficiency-question/]Geometry Data Sufficiency[/url] problems. [/*] [*]If a GMAT math problem asks you whether a point is on a line, plug the coordinates of the point into the equation for the line. If you get a valid result, then the point is on the line. For example, the point (2, 6) is on the line y = 2x + 2.[/*] [/list] [b]Word Problems[/b] [list] [*]The average of a set of numbers always has to be somewhere in the middle of that set. It can’t be larger than the largest number in the set, or smaller than the smallest number. This is useful for weighted average problems: if you average the weights of 6 cats that each weigh 10 pounds, and 8 dogs that each weigh 30 pounds, the result will be somewhere in the middle in between 10 and 30. The more evenly spread the numbers are, the closer the average will actually be to the middle. [/*] [*]Only use a Venn diagram for rare “3-group” overlapping set problems. For almost all overlapping sets, the Overlapping Set Matrix is quicker and easier. [url=https://www.manhattanprep.com/gmat/blog/how-to-handle-3-group-overlapping-sets-on-the-gmat/]Both are described in this article[/url]. [/*] [*]You’ll sometimes see rates problems that look like this: if it takes four people twelve days to sew eight jackets, how long does it take ten people to sew ten jackets? A quick trick for approaching these is to start with the original statement, and then “scale” it upwards or downwards. Here’s what that might look like: [/*] [/list] It takes 4 people 12 days to sew 8 jackets. 1 person will take 4 times as long to do the same amount of work, so it will take 1 person 48 days to sew 8 jackets. If that 1 person sews ⅛ as many jackets, it will take ⅛ as many days. So, it takes 1 person 6 days to sew 1 jacket. If a person takes 6 days to sew a jacket, then it will take 10 people 6 days to sew 10 jackets (one per person). The answer is 6. [b]Fractions, Decimals, and Percents[/b] [list] [*]When a fraction has zeroes on the end of both the numerator and the denominator, chop off the same number of zeroes from each (just make sure you count carefully!). 1,000,000 / 5,000 simplifies to 1,000 / 5. [/*] [*]Likewise, if a fraction has decimals in both the numerator and denominator, you can simplify by moving both decimal places by the same amount and in the same direction. For instance, 0.0007 / 0.14 = 0.007 / 1.4 = 0.07 / 14 = 0.7 / 140 = 7 / 1,400. [/*] [*]Use [url=https://www.manhattanprep.com/gre/blog/heres-the-safest-way-to-handle-gre-percentage-problems/]this technique to directly translate percent problems from English into math[/url] without having to convert between decimals and percents. [/*] [/list] [b]Working with Numbers[/b] [list] [*]You can use a similar ‘scaling’ technique to calculate percents, fractions, or decimals. For instance, if you want to find 0.1% of 50,000, start like this: [/*] [/list] 10% of 50,000 is 5,000. So, 1% of 50,000 is a tenth of 5,000, or 500. So, 0.1% of 50,000 is a tenth of 500, or 50. The answer is 50. [list] [*]To quickly divide a number by 5, divide it by 10 first, then multiply by 2. For example, 1,880/5 = 1,880/10 * 2 = 188 * 2 = 376. [/*] [*]Arithmetic can be easier if you “split up” or rearrange the numbers before you do the math. Suppose that you need to calculate 117 – 98. Rewrite this as 117 – 100 + 2, or 17 + 2, which equals 19. [/*] [*]Use a similar technique to quickly calculate the square of a number that’s close to an easy value.[/*] [/list] 79² = (80 – 1)² = 80² – 2(80) + 1 = 6,400 – 160 + 1 = 6241 [list] [*]To find a good common denominator, think of a value (if there is one) that both numbers are divisible by. Divide [b]one[/b] of the two numbers by that value. Then, multiply that by the other number. [list] [*]For example, to find a common denominator between 25 and 15, note that both are divisible by 5. So, divide 25 by 5, which gives you 5, then multiply that by 15, giving you 75. 75 would be a good common denominator.[/*] [/list] [/*] [*]It can be useful to memorize the approximate square roots of 2 and 3: √2≈1.4 and√3≈1.7. To remember this, at least if you’re in the US, think of two dates: Valentine’s Day is on 2/14 and St. Patrick’s Day is on 3/17. [/*] [*]To estimate other square roots, think of a perfect square that’s as close as possible to the value you’re dealing with. (You have your perfect squares memorized, right…?) Estimate based on that—so, for instance, √79 is a bit smaller than √81, which equals 9. [/*] [/list] [b]What Next?[/b] Math isn’t the most important part of the GMAT math section! [url=https://www.manhattanprep.com/gmat/blog/what-the-gmat-really-tests/]Strong executive reasoning skills trump math knowledge[/url]. So, while these tips and tricks are useful, if you’re having a tough time with the math section, incorporate some work on [url=https://www.manhattanprep.com/gmat/blog/everything-know-gmat-time-management-part-3/]timing[/url], [url=https://www.manhattanprep.com/gmat/blog/which-gmat-problems-should-i-guess-on-part-3-making-great-guesses-on-quant-problems/]guessing[/url], [url=https://www.manhattanprep.com/gmat/blog/the-4-math-strategies-everyone-must-master-part-1/]problem-solving strategies[/url], and [url=https://www.manhattanprep.com/gmat/blog/how-to-handle-gmat-stress-without-freaking-out/]stress management[/url].

FROM Manhattan GMAT Blog: GMAT Rate Problems |
If this post is 1500 words long, and you can process 120 words per minute, then how long will it take you to read this whole post? If you could read 20% faster, then what effect would that have on how long it takes you to read the whole thing? If I were adding 80 words per minute to the blog post, then how long (at your original speed) would it take for you to reach the end? Those questions were a taste of the often daunting world of GMAT Rate problems. Before we get any deeper, we should acknowledge that Rate problems do not seem to be tested as frequently on GMAT Quant nowadays as they once were. So while you’ll see plenty of Rate problems in the Official Guides and on Manhattan Prep’s practice GMATs (take a free one), you might not see many or any of these on your real GMAT. Nevertheless, Rate problems are one of the most common requests I get from tutoring students. Because these problems usually come in Word Problem format and take on many different flavors, students frequently feel like there is too much density or variety for them to handle. Indeed, there are a variety of moves we might employ, and a variety of formulas/relationships that would be useful to know, depending on the situation. Let’s discuss. Useful Formulas onto flashcards until they’re 2nd nature.[/*] [*]The biggest thing that helps me is Making Up My Own Number for Distance or Work, when one isn’t provided.[/*] [*]To get some harder questions correct, you may find that Scaling Up Ratios or Reciprocal Thinking is the easiest way to arrive at the answer.[/*] [*]It can pay to develop some chops at Approximating, especially since some of these problems might be good contenders for skipping.[/*] [/list] You can attend the first session of any of our online or in-person GMAT courses absolutely free!

FROM Manhattan GMAT Blog: GMAT Data Sufficiency: Get 5 Extra Minutes |
What if I told you that you could have five extra minutes on the quantitative section of the GMAT? Would you be interested? Good, because this is going to get a little technical. I’m also going to assume you’ve had some experience with Data Sufficiency problems on the GMAT Math section. You should also have practiced testing cases to solve these problems: here’s a good introduction to that strategy in case you’re unfamiliar. Part 1: Practical Application Now, to save yourself the five minutes I promised, you have to understand something I’m naming the Moliski Theorem. Though I’ve heard it discussed by several people, I’m naming it after my colleague Liz Moliski, who was the first person I saw actually float this idea while teaching a class. The theorem applies to any Data Sufficiency question that has a yes/no answer. For example, the theorem is applicable to this Data Sufficiency question: Did Rocky the dog eat more dog treats this year than he did last year?
How many dog treats did Rocky the dog eat this year?
That’s it! Is your mind blown yet? Cause mine is. You see, up until I saw Liz teach, I’d always assumed you needed two concrete examples of the statement that got you two different answers to the question in order to show that the statement is not sufficient. Defining those examples was time-consuming. The Moliski theorem not only obviates the need for the second example, it also makes it extremely simple to define the single example you’re looking for. Since I now only need to define and find half the examples than I did before, I have been able to solve Data Sufficiency problems in half the time that it took me previously, going from two minutes (on average) down to one. I have seen at least five yes/no Data Sufficiency questions on each of my practice tests, meaning this idea has bought me at least five full minutes of extra time. I’m going to show you a Data Sufficiency problem. Try to solve it on your own first. Then we’ll apply the Moliski theorem. If x and y are integers, is the product xy even?
Now let’s find our examples. Can I find an example of statement (1), which says x – y xy is odd? Sure I can: 7 and 5, for example. 7 – 5 is 2, that’s less than 3. The product 7 · 5 is 35, which is odd. Statement (1) is therefore not sufficient. Moving on to statement (2): I want to find numbers where x + y is odd, and also where the product xy is odd. Well that’s impossible, since if x + y is odd, then one or the other must be even, meaning when I multiply them together, there’s no way I’ll ever get an odd number. Since I couldn’t find my example, statement (2) is sufficient. Now we know that the correct answer is (B). Are you excited yet? Try this super-tough problem: Is x > 0?
Try to find a negative number x that would make statement (1) true. So, I know that x2 x be negative? Sure, as long as it’s a negative fraction like –12. Statement (1) is not sufficient. Now try to find a negative number for x that would make statement (2) true. If x3 > x, can x be negative? There’s no reason to reinvent the wheel, let’s just use x = –12 again. If you cube that, it’s greater than what you started with. So statement (2) is also not sufficient. And oh, by the way, since –12 is an example that satisfies both statements, and gives us the “no” answer we’re looking for, the correct answer to this question is (E). LET’S GOOOOOOO Part 2: A Small Caveat and Other Non-Essential Nerdy Stuff That You Can Read If You’re Interested, but I’m Mostly Writing It Because I Don’t Want Liz to Get in Trouble Occasionally, the Moliski theorem fails. Here’s an example: Is x > 10?
Don’t, however, let the rain fall on your parade quite yet. The “always no” situation is exceedingly rare; in my professional experience, it shows up on roughly 1% of all Data Sufficiency questions (probably even fewer, to be honest). So, we are still looking at a strategy that works 99+% of the time and saves you 5+ minutes: personally, I’m willing to accept that risk. Finally, here’s what I think is the true genius of the Moliski theorem: It sidesteps the single most common error I see my students make when tackling Data Sufficiency problems, which is to misinterpret the question as a rule. By explicitly hunting for a “no” answer, the Moliski theorem forces you to consider that negative possibility right upfront, so that you don’t have to remember to look for it later when you’re already knee-deep in a fog of calculations and algebra. Epilogue When I first started teaching the GMAT, I never dreamed I’d see a day when I could get away with testing just one case per Data Sufficiency statement as opposed to two. Now that day is upon us. I hope your life is as changed as mine. You can attend the first session of any of our online or in-person GMAT courses absolutely free! We’re not kidding.

FROM Manhattan GMAT Blog: How to Succeed in Business School |
Your business school wants you to have a successful career. There’s one cynical reason and one neutral reason why: the cynical one is that if you do have a successful career, you will tell everyone you know that you went to, say, the Rady School of Management, and then those people will then want to send their application fees, and ultimately their tuition checks, to said institution, and if you have a really successful career, you may even get in touch with your philanthropic side and get a building named after you at your alma mater. The neutral one is that business schools exist to help you grow the national economy, and your success is the school’s (and ultimately the nation’s) success. Whatever your personal outlook is on the matter, your business school does want you to succeed, and knowing that can help you in a few ways. How to Succeed in Business School: The Application Let’s start with the application process. One of the best tools business schools have at their disposal for ensuring their students succeed after graduation is the ability to select students whom they believe will succeed. This seems like an obvious point, but it completely explains the Olympic athlete with a GMAT score that’s 100 points lower than yours in the chair next to you when you go to do campus visits. I don’t care if she doesn’t know how many factors 441 has, that young woman can do a gainer with two and a half somersaults like nobody’s business, and more to the point, she had to work for years with single-minded focus towards a goal that very few people ever achieve. I think she’s sufficiently demonstrated the skills to succeed in the workforce; wouldn’t you agree? Now, you may not be an Olympic athlete, but you have certainly persevered through adversity before. You may have gotten a promotion at your job, or even been charged with leading a new team at your company. You have done something in your life that will show an admissions committee that you will be successful in your career; your best bet is to figure out what that is and highlight it. How to Succeed in Business School: Once You’re In Once you’re done with your applications, you’ve been accepted, and you arrive on campus, your school will be there to support you. At most schools, you’ll be placed in a study group of around 4 or 5 students, and you’ll turn in all your homework as a group; your school is trying to prepare you to work with diverse teams. You’ll take a core curriculum for a large part of your first year; your school wants you to have a basic understanding of accounting, operations, economics, marketing, finance, and organizational strategy. A criticism I’ve read of business schools is that classes are not as academically rigorous as they would be in other graduate-level programs, but I think that criticism might be somewhat beside the point since business school serves a slightly different purpose: you should go to your classes not necessarily because you want to become an expert in one particular subject, but rather you should go because you will learn the language of business, and you will gain insights that will help you better manage your team or organization down the road. You’ll also have access to school clubs, trips, networking events—you name it. Again, all of this is intended to give you a leg up in your career. Takeaways Here’s the point: your school wants you to succeed, and the way to do that is:
