FROM Magoosh Blog: GMAT Canceled? You Can Take it At Home 
Magoosh will update this post as more information becomes available. Latest update: April 14, 2020 Due to the new coronavirus, many of you have had your inperson GMAT exams canceled. Graduate Management Admissions Council (GMAC), the makers of the GMAT, announced that they have launched their Interim GMAT Exam, allowing students take an online GMAT exam at home. When Can I Take AtHome GMAT Exam? The GMAT Online Exam is available for registration as of April 14, 2020! The online GMAT will be available to take 24 hours a days, 7 days a week, with available slots beginning April 20, 2020 until June 15, 2020. Who’s Eligible? GMAC plans to release the interim GMAT option to anyone in a market impacted by COVID19. The exceptions are Cuba, Iran, North Korea, Sudan, Slovenia, and mainland China due to IP and/or regulatory restrictions. How Similar Is the Interim Exam to the Regular GMAT? The athome exam will be cheaper, coming in at $200 USD for registration, where the inperson exam registration costs $250 USD. There will be no AWA section. That feels like a substantial change in that you have thirty fewer minutes of testing. That’s 16% of your wouldbe total testtaking time! The test will still have the Quant, Verbal, and IR sections, with the same amount of questions and time available as the inperson exam. That is, there will still be:
Taking the online exam will not count towards a student’s 12month and lifetime GMAT limits. Usually, students are only allowed to take the GMAT no more than 5 times in a 12month period, with a lifetime availability of 8 total GMAT exams possible. That said, students may only take the online exam once. Regarding checkin protocols, the GMAC has said, “The checkin and security protocols will be modified to accommodate online delivery and remote proctors will be used to manage test integrity.” While we don’t know the specifics, we do know how the GRE is approaching athome testing: recording your face via webcam and your screen as well as mandating specific equipment and setup requirements. I wouldn’t be surprised if the athome GMAT requires similar measures and requirements. TL;DR
If you’re finding yourself with an interest in applying to business school, having more free time on your hands to take the GMAT, and you have a private space at home where you could take a test, you may want to consider it. You’ll potentially be able to practice in the exact same environment as that of test day, and you’ll have a test that is thirty minutes shorter than the inperson GMAT. We’ll update you as we learn more, so keep an eye on this blog. In the meantime, if you’re still studying, you can use our GMAT prep product, which has been used by over 50,000 students. You can also read the full announcement on the GMAC website here. The post GMAT Canceled? You Can Take it At Home appeared first on Magoosh GMAT Blog. 
FROM Magoosh Blog: GMAT Geometry Practice Problems 
GMAT Geometry problems test your spatial reasoning ability. Can you look at a diagram of points, lines, and/or circles and extract the essential details that lead to a correct answer? If you answered no, well, have no fear! After reading this post, learning the fundamental geometry formulas, and working through these practice geometry questions, you will have the tools you need to succeed on test day! How to Use Geometry Formulas [*]GMAT Geometry Practice (Problem Solving Questions)[*]Additional GMAT Geoemtry Practice (Data Sufficiency Questions)[/list] memorize a bunch of formulas. By themselves, formulas cannot guarantee you a great score on the GMAT Quant section. You also need to know when and how to apply the formulas. Furthermore, it’s rare that a problem would require only a single formula to solve it. Most often, you’ll need to put a few different formulas together like pieces of a puzzle. The best problemsolvers take a goaloriented approach. In other words, start with what you need to solve. Then work backward, identifying what info would be useful to get to that goal. In addition, you need to keep in mind the given info, both from the diagram and also from the question statement. Use that to build a bridge to your goal. This post walks you through the most important formulas for GMAT Geometry. The purpose here is just to help you review—so click on the links to learn more about the material. Then, you can try out your skills on a set of geometry practice questions. Detailed solutions are given at the very end. Ready? Let’s go! geometry formulas.

FROM Magoosh Blog: MBA Admissions in the Time of COVID19 
If you’re wondering what is going to happen to the application process when applicants can’t sit for exams or attend admissions interviews in person due to the new coronavirus, you’re not alone! The application process is changing quickly due to COVID19. Programs are taking different approaches, leaving a lot of people wondering what to do. You should pat yourself on the back for applying during a time when everything is changing! To help you create a game plan, we’ll highlight some of the biggest trends. Let’s go through some info to give you some more ideas about what to expect. More of a visual person? We interviewed an MBA admissions expert with 15+ years of experience getting students into their dream schools. The video is coming soon, but we can give you a sneak preview! It will include these three key points:
How can I take the GRE or GMAT if test centers are closed? The GRE is online. ETS has been offering an athome option for testtakers since early April and it’s available to all markets except China and Iran. You’re in luck if you’re a GMATtaker! The athome exam went live on April 14, 2020. It appears that there are a few changes:
What about those needing special accommodations? If you require any special accommodations (usually medically related), be sure to call in to ETS or GMAC to reserve a testing date, rather than booking online. What if my testing center hasn’t closed? While it’s possible to schedule an online exam anyway, it would probably be ideal to sit down with a proper writing pad and 10minute breaks in a test center (if safe, of course)! This is up to your personal preference as well. However, if the center closes and your test is canceled, then we recommend going online and booking the athome exam. Is one test preferred above the other? The short answer: not really. There are some programs that only accept the GMAT, but they are becoming rarer by the year. COVID19 has not changed this part of the admissions process. Is the score requirement postponed? For the most part, yes. Most programs will allow an application to be submitted followed by a score later. Be sure to utilize the essay in your application to mention that you will be sending the GMAT later. However, on the finer details, we’re going to have to defer to “it depends,” which can be frustrating for someone when they’re trying to make a plan, but we’ll explain why we say this. Each program is going their own way and the changes are happening fast! For example, Kellogg is waiving the need for the GMAT/GRE altogether for Round 3 while other universities are extending the deadline for the test (or all of Round 3) into the summer. Conversely, some universities, like Stanford, are sticking to their original deadlines and not making exceptions. At the bottom of this resource, we’ve linked to some of the most commonlysearched programs, which is a good starting point. What if someone took the GMAT/GRE and didn’t like their score? Should they submit an application without mentioning it and just retake the exam? It’s fine to just say you’ve taken the test before and submit your score. They’re going to see it anyway! You could indicate on the essay that you’re planning on retaking it to get a higher score. You can even indicate whether you’ve been testing higher on practice exams, showing that you’re reasonably expecting a better score. Then, of course, try your best to do so! Can I take the EA (Executive Assessment) online? GMAC is opening up registration for the EA at the end of April. If the GMAT registration is any indication, there will likely be multiple time slots from which you can choose. Other Changes to MBA Admissions We’ve listed some trends and topics that may be topofmind, but will defer to links to programs’ websites so you can get the most uptodate information when it comes to their new requirements and information. Should applicants consider Round 3? The conventional wisdom has been to beat the GMAT and then ideally apply for Round 1 or 2, but COVID19 has introduced a lot of exceptions to this rule. Typically, anticipation of harder times in the jobs market (e.g., 2001 or 2008) has led to increased applications to graduate programs. Professionals who have lowered expectations of nearterm career prospects often think about pursuing an MBA while they wait out the difficult times. Consider this time: if medical professionals are correct that a vaccine might be ready in 1218 months, then a twoyear program doesn’t seem like a bad idea for a lot of soontobe applicants! Now, at Magoosh we’re not medical professionals, so we have no idea whether that medical timeline is accurate or not, but we can reasonably expect Round 1 for 2021 entry to be more competitive than it would have normally been! This means Round 3 (for 2020 entry) has become the exception; it’s looking less competitive than Round 1 or 2 in the autumn (for 2021 entry). Many applicants don’t prefer an online semester and are deferring their entry, opening up new spots in the process. On top of that, schools are extending their deadlines into the summer, and many are showing extra leniency when it comes to deadlines for the exams themselves. That doesn’t mean that you have to apply now, of course, but it means that those who are already in the middle of studying might want to weigh their options! Virtual Events, Interviews, and (Possibly) Online Semesters In the past year, interviews with alumni or staff (and acceptedstudent ceremonies and orientations) have been inperson. Most programs have found ways of doing this over the phone or virtually using video conferencing software. There are only a handful of universities that have considered online semesters so far. We list a fair amount of links to universities below, but we encourage you to keep an eye on your chosen programs. University of Arizona, for example, has already made it clear they are going entirely online for the near future. We expect in the coming months to get a lot more clarity, as many universities would prefer not to do so unless it’s necessary. Links to CommonlySearched MBA Programs’ COVID19 Responses Remember when we said that programs and their requirements are changing rapidly? We recommend bookmarking the pages that are most relevant to your applications. Here are the official links to their information pages.
MBA Admissions During COVID19: Conclusion Programs are often changing requirements and shifting deadlines, so it’s not going to be easy to apply in these times. However, the fact that you’re researching this right now means that you’re willing to try to find a way to develop in spite of the difficulties. Pat yourself on the back! Are you applying for business school right now? What challenges have you encountered? Comment below! The post MBA Admissions in the Time of COVID19 appeared first on Magoosh GMAT Blog. 
FROM Magoosh Blog: GMAT Data Sufficiency – Tips and Practice Problems 
The GMAT Quantitative section contains two types of questions, Problem Solving and Data Sufficiency. On the GMAT, the format of each Data Sufficiency problem is the same: you’re given a question and two statements. It’s up to you to decide whether the statements give you enough information to answer the question. You don’t need to give the answer to the actual question. You just have to decide whether either statement (or both statements) gives data that is sufficient for finding an answer—hence the term data sufficiency! What is GMAT Data Sufficiency? The Data Sufficiency (DS) section is extraordinarily apt for the GMAT, as it tests uniquely managerial skills. It’s often more about logic and critical reasoning than deep mathematical knowledge or ability. On the GMAT Quantitative section, you get 62 minutes for 31 questions—of these 31 questions, approximately 1113 will be Data Sufficiency questions. Furthermore, there are two kinds of data sufficiency question: Yes/No and Value questions. We’ll see plenty of each type in the practice problems below. Each practice problem illustrates an essential tip for success. So let’s get started! The following six tips will help prepare you for these uniquely challenging problems. GMAT DS Tip #1: Memorize the Answer Choices The answer choices always consist of the same five options in the same order. You should memorize these now!
GMAT DS Tip #2: Consider the Statements Separately For GMAT Data Sufficiency problems, you first have to consider whether each statement, by itself, is sufficient. Only if both statements are not sufficient separately would you consider the sufficiency of the information in the combined statements. One common mistake is to carry over information from Statement (1) into Statement (2). You have to “wipe the slate clean” after looking at Statement (1). Helpful strategy: Consider whichever statement is the simplest first. That’s because the GMAT loves making Statement (1) a huge, complicated, juicy statement and Statement (2) something incredibly brief. If that’s the case, consider Statement (2) first. Practice Problem If \(x^2(y – 3) = 0\), then what is the value of \(y\)? (1) \(y^2 – x= 0 \) (2) \(x= 7 \) A. Statement (1) ALONE is sufficient, but Statement (2) alone is not sufficient to answer the question asked. B. Statement (2) ALONE is sufficient, but Statement (1) alone is not sufficient to answer the question asked. C. Both Statements (1) and (2) TOGETHER are sufficient to answer the question asked; but NEITHER statement ALONE is sufficient. D. EACH statement ALONE is sufficient to answer the question. E. Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data specific to the problem are needed. Click here for the answer B. Statement (2) ALONE is sufficient, but Statement (1) alone is not sufficient to answer the question asked. While Statement (1) is not really that complicated, Statement (2) is as simple as it gets. So let’s start there. If you know that \(x = 7\), which is of course nonzero, then \(x^2\) is also nonzero. Thus, the other factor \((y – 3)\) must be equal to 0. From there you can find the value of \(y\) (which will be 3; not that you really need that value to answer the problem). So, Statement (2) is sufficient. That helps you to eliminate a bunch of choices (see GMAT DS Tip #3). Now let’s go back to Statement (1). Forget any values of \(x\) or \(y\) from the previous work. If \(y^2 – x= 0 \), then \(x = y^2 \). Substitute this expression into the given equation: \( (y^2)^2(y3) = y^4(y3) = 0 \) So, does that tell you what \(y\) is? Well, not exactly. Here, \(y\) could be either 0 or 3. So Statement (1) is not sufficient by itself. GMAT DS Tip #3: Smart Elimination GMAT Data Sufficiency problems test your logic skills as well as mathematics. Let’s look at a flowchart to help land on a correct answer. This is based on examining Statement (1) first, but a similar flowchart would apply if you looked at Statement (2) first instead. So let’s talk about the choices, starting at Statement (1).
Here’s a Magoosh video that you might find useful: Data Sufficiency: Eliminating Answers. Practice Problem Let’s try out our elimination strategy! Click on this practice problem from Magoosh. The solution follows. Click here for the answer D. EACH statement ALONE is sufficient to answer the question. Consider Statement (1) first. Suppose there are \(x\) widgets, and the price of each one is \(p\). From the given information, then we know that \(xp = 480\). Statement (1) can be interpreted mathematically as follows: \(x(p2) = 480 – 160\), or \(xp2x = 320\) Since we know the value of \(xp\), the above equation can be used to solve for \(x\), and then you can derive \(p\) directly from the fact that the product is 480. Ok, so Statement (1) is sufficient. Thus, we can eliminate three choices, B, C, and E! Next, look at Statement (2). This one can be translated into mathematics as follows: \(x(p+1.50) = 480 \cdot 1.25\), or \(xp+ 1.5x = 600\) It’s a similar situation, and we’d easily be able to solve for both variables. This is enough to narrow down the correct answer. GMAT DS Tip #4: Avoid the Temptation to Calculate the Answer GMAT Data Sufficiency is all about the question, “Could you find the answer?” Suppose the prompt is “What is the value of \(x\)?”, a standard DS problem. Now maybe in the course of solving this problem, you get to a step like \(23x^3 + 144 = 5670\). The apprentice problemsolver with poor managerial instincts will dutifully work through the several steps necessary for finding the actual value of \(x\)—without access to a calculator, mind you. On the other hand, the master GMAT testtaker would realize: “From that equation, I could solve for the unknown if I wanted to.” That, in and of itself, answers the sufficiency question right there, and that’s all you need to do! The actual value of \(x\) is irrelevant. Practice Problem Try your hand at this question. Click here for the answer D. EACH statement ALONE is sufficient to answer the question. First, the given information is very helpful. If we let \(x\) stand for the number of visitors on day 1, then on day 2 we’d have \(x + 3\), and day 3 would be \(x + 6\), etc. By the time day 7 rolls around, there would have been \(x+18\) visitors. Statement (1) tells you the total number of visitors. Avoid the temptation to solve an equation here. All you need to know is that \(x + (x+3) + (x+6) + \cdots + (x+18) = 126\) is an equation in a single variable. Even better, it’s a linear equation, which is guaranteed to have a solution. It doesn’t matter what the solution actually is; Statement (1) is sufficient. Similarly, Statement (2) boils down to the equation, \(x+18 = 3x\)—also quite solvable. Both statements are sufficient individually. GMAT DS Tip #5: Focus on Sufficiency On the GMAT test, Data Sufficiency problems may be quite misleading, especially those of the “Yes/No” variety. As discussed above, you’re not looking for the answer, but rather could you find the answer? And sometimes that answer is “no.” Practice Problem Is \(t < 0\)? (1) \(4^t\) is an integer (2) \(4t^2 + 8t = 0\) A. Statement (1) ALONE is sufficient, but Statement (2) alone is not sufficient to answer the question asked. B. Statement (2) ALONE is sufficient, but Statement (1) alone is not sufficient to answer the question asked. C. Both Statements (1) and (2) TOGETHER are sufficient to answer the question asked; but NEITHER statement ALONE is sufficient. D. EACH statement ALONE is sufficient to answer the question. E. Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data specific to the problem are needed. Click here for the answer A. Statement (1) ALONE is sufficient, but Statement (2) alone is not sufficient to answer the question asked. Statement (1) would imply that \(t = 0, 1, 2, 3, \ldots\) (remember, negative exponents would give fractional values). In others words, \(t\) is decidedly NOT less than 0. But that shows Statement (1) to be sufficient to answer the question. For Statement (2), let’s do a little factoring. \(4t^2 + 8t = 4t(t + 2) = 0\) So we can see that \(t=0\) or \(t = 2\). Since there are two possibilities, one of which is less than zero (2[/latex]), and the other not less than zero (0), Statement (2) is insufficient. GMAT DS Tip #6: Testing by Plugging in Numbers Caution: There are more numbers than just the natural numbers, a.k.a. the counting numbers: 1, 2, 3, 4, and so on. People often forget that a “number” could be positive or negative or zero, could be a fraction, could be a square root, could be \(\pi\) or some other decimal, etc. The possibilities are literally uncountable! The GMAT loves to test number properties, and one of the greatest pitfalls you could make is to think of “\(x\)” as only a natural number when you go to answer the question. Practice Problem Is \( x \geq \dfrac{1}{x} \) ? (1) \(x\) is positive. (2) \(x \geq 1 \). A. Statement (1) ALONE is sufficient, but Statement (2) alone is not sufficient to answer the question asked. B. Statement (2) ALONE is sufficient, but Statement (1) alone is not sufficient to answer the question asked. C. Both Statements (1) and (2) TOGETHER are sufficient to answer the question asked; but NEITHER statement ALONE is sufficient. D. EACH statement ALONE is sufficient to answer the question. E. Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data specific to the problem are needed. Click here for the answer C. Both Statements (1) and (2) TOGETHER are sufficient to answer the question asked; but NEITHER statement ALONE is sufficient. This one is definitely tricky! Don’t try to solve anything algebraically; that may lead you astray. Instead, let’s pick some good numbers to plug in each statement. Let’s start with Statement (1). Plugging in a typical positive number such as 1 or 2 results in a correct inequality. For example, \( 2 \geq \dfrac{1}{2} \). But be careful! What about numbers that are positive fractions? What about \( x = \dfrac{1}{3} \), for instance? \( (1/3) \geq \dfrac{1}{(1/3)} =3\) would yield an untrue statement! Therefore, Statement (1) is not sufficient to answer the question. Ok, so what about Statement (2)? The absolute value gives it away. Think about both positives and negatives here. You already know that a positive number like 2 leads to a true inequality. What about \(x=2\)? \( (2) \geq \dfrac{1}{(2)} = 0.5\) This is a false inequality! So we have two opposite conclusions, meaning that Statement (2) is also insufficient. Well, if you’re following along using the flowchart from GMAT DS Tip #3, you may realize that we still need to check one more thing. Are the two statements TOGETHER sufficient? If \(x\) is both positive (Statement (1)) AND has absolute value \(\geq 1\) (Statement (2)), then there is enough to prove the given inequality to be true for all such \(x\). Conclusion and More Data Sufficiency Practice! GMAT Data Sufficiency problems can be very challenging. However, if you keep the six tips above in mind, you’ll be well on your way to higher and higher GMAT scores on test day! Try out these additional practice problems from Magoosh!

FROM Magoosh Blog: Algebraic Equations with Fractions on the GMAT 
Algebraic equations with fractions, more formally known as “rational expressions,” appear in some of the most challenging GMAT algebra questions in the Quant section. These are called “rational” in the sense of “having to do with a ratio”, as the word is used in the phrase “rational numbers“. Click here to go straight to the practice problems. Thoughts on Algebraic Equations with Fractions First of all, to understand this stuff, you should be clear on the basic rules of fractions: how to add, subtract, multiply, and divide them. If you can’t do this basic arithmetic with numerical fractions, it will be very hard to do it with algebraic rational expressions! Some further tips: 1. Suppose you have an equation involving one or more algebraic rational expressions. Suppose you are asked to solve for values of the variable. It’s important to note that any value of the variable that makes any individual denominator equal to zero cannot possibly be a solution of the equation. This can be a powerful tool in “which of the following could be a solution” question, because usually you can immediately eliminate a few answers right away, which sets you up very well for backsolving or solution behavior. 2. When adding or subtracting rational expressions, as when adding or subtracting ordinary fractions, we must find a common denominator to combine. We must do precisely the same thing with rational expressions. Here are a couple examples of this process. Example #1 Example #2 3. Whenever you have just one algebraic fraction on one side of the equation equal to just one algebraic fraction on the other side of the equation, then you can crossmultiply. If either side has more than one fraction, added or subtracted, you would have to combine them, via the previous hint, before you are ready to crossmultiply. 4. If the whole equation has only one or two denominators, you also can simply multiply every term on both sides by the denominators. That can be a very efficient way to get rid of all the fractions in one fell swoop. For example, the equation: can be simplified by multiplying each term by (x – 2) — with the fraction, it cancels the denominator, simply leaving the numerator. x(x – 2) = 2(x – 2) + 1 If we were to multiply this all out, we would get a quadratic that we could solve. 5. One could always use a direct algebraic solution: that may be efficient or that may take several steps and be timeconsuming, even if you know you are doing. Remember that backsolving may be quicker. For a compound fraction (a big fraction with a little fraction in the numerator or denominator), it may well be quicker to step back and perform a more holistic solution, looking at what must be true about each piece: I demonstrate this in the solution for practice problem #2. The two sides are not equal, so (B) can’t be the right answer. At this point, we pretty much know that (C) must be the answer, but it’s always good to verify that it works. Both sides are equal, so x = 0 satisfies this equation. Therefore, answer = (C). Show Answer and Explanation Rather than do a ton of algebraic rearranging, let’s think about this. We have 3 divided by (something) equals 1/2. This means, the “something” must equal 6. That immediately produces the much simpler equation: Answer = (A)
(B) one (C) two (D) a finite number greater than two (E) infinitely many Show Answer and Explanation Multiply all three terms by x and we get This equation is unfactorable. It is not a perfect square. Think about its graph, which is a parabola: When x = 0, y is negative, and when x = 2, y is positive. Therefore, the parabola intersects the xaxis twice, which means the equation has two real solutions. Answer = (C). BTW, this is a special mathematical equation. One solution is the Golden Ratio, and the other solution is the negative reciprocal of the Golden Ratio. Show Answer and Explanation This is an easy one to solve. Subtract 2 from both sides: Now, add 3/y to both sides. Because the two fractions have the same denominator, y, we can just add the numerators: Answer = (E) 5. As y increases from y = 247 to y = 248, which of the following decreases?
(B) II only (C) III only (D) II and III only (E) I, II, and III Show Answer and Explanation As y gets larger, what happens to each one of these? For statement I, as y gets larger, the 2y gets larger. Since the subtracting 100 stays the same as the value of y changes, that makes no difference. This one increases as y increases, so it is not a correct choice. For statement II, as the denominator of a fraction increases, the value of the fraction overall decreases. When y increases, 50/y has to decrease. Again, adding 80 remains the same as y changes, so this doesn’t make any difference. This is a correct choice. For statement III, as long as y > 3, then y^2 – 3y will increase as y increase. That means the entire fraction decrease. We are subtracting 100 minus the fraction, and if the fraction gets smaller, then we are subtracting something smaller and therefore are left with more. This means the entire expression, the difference, gets bigger as y increase. This one increases as y increases, so it is not a correct choice. Answer = (B) You’ve reached the end of practice round 1! Grab a snack, get up and stretch, then get ready for practice round 2 for algebraic equations with fractions. Practice Round 2: Manipulating Algebraic Equations with Fractions This next set of practice problems and explanations takes you through a range of scenarios you might encounter on GMAT Math. If you’re looking to practice specific areas, feel free to jump around. But if you’re still struggling to apply what you’ve learned about algebraic equations with fractions to actual problems, be sure to tackle the problems and explanations in order. Show Answer and Explanation Expressions Let’s begin with “Do what’s mathematically sound.” When you multiply through by a common denominator, you’re changing the value of every single term (except when the term is equal to zero or the denominator is equal to one). That’s okay when you’re dealing with an equation, so long as you do exactly the same thing to both sides of the equation, but it’s not okay when you’re asked to evaluate an expression. It may be tempting to multiply through by 10, the least common denominator, but that will yield an answer ten times too great. Instead, take a look at the answers to see what form they take, and manipulate the expression toward answers of that form. It looks as though we’ll want to get the m and n denominators together. We can accomplish this by giving them a common denominator. In this case, that means multiplying the term \( m/5 \) by \( 2/2 \), to get \( {2m}/10 \). Notice that this effectively multiplying \( m/5 \) by 1. The single most commonly useful way to manipulate an expression is to multiply it by 1. Since the two terms now have the same denominator, we can join the numerators. If it not clear how to translate that further, then rewrite it as, Since 1/10=0.1, you can finally rewrite the expression in the useful form. 0.1(2m+n) Before we turn to the more interesting cases, let’s be reiterate explicitly the lessons we can draw from this example:
Show Answer and Explanation Expressions Pt. 2 Because this is an expression rather than equation, we don’t have the option of multiplying through by a common denominator. What could we do? Well, as we saw in our last post, the single most commonly useful way to manipulate an expression is to multiply it by 1. But wait! Isn’t there a standard way to manipulate a compound fraction? Should we use that instead? Yep, and as we’ll see, that standard way to manipulate a compound fraction is just one way to multiply the expression by 1. You may remember that the standard way to divide by a fraction is to multiply by the reciprocal of that fraction; lots of American students learn this as “invert (the denominator) and multiply (by that inverse).” That mnemonic works well enough, but it may obscure the underlying logic. Let’s go ahead and manipulate for now, and then double back and tackle the underlying logic. Let’s rewrite the problem so that we’re multiplying the numerator (x/5) by the reciprocal of the denominator: \({x/5}/{10/y}\) becomes \({x/5} x {y/10}\) which in turn becomes xy/50. As with the problem from my last post, we’d better take a look at the answer choices to see what form our expression should take. We’re going to want it in the form of answers C, D, and E: a decimal fraction multiplied by the expression . If you can’t translate automatically, do it in stages: xy/50 \( {(1/50)}(xy) \) \( {(2/100)}(xy) \) (0.02)(xy) 0.02xy Remember that I wrote above that multiplying by the reciprocal (or “inverting and multiplying”) is just a special way of multiplying by 1? Let’s see why. Consider the general form \({a/b}/{c/d}\). We could simplify this fraction by multiplying by a special form of 1, \({d/c}/{d/c}\): Of course, that’s the very same result that you’d get by going directly to “invert and multiply.” Fortunately, if you’re wellpracticed with that maneuver, you don’t need to worry about the underlying logic during the test. Show Answer and Explanation Equations This is where we turn from “Do what’s mathematically sound,” to “Do what’s useful.” When you’re solving an algebraic equation, what’s generally useful is to clear away all the grouping symbols, that is, the parentheses, division bars, and radical signs. Doing so allows you to move around the variables and constants in whatever way you like. There will be exceptions, but your default move when you see an algebraic equation with fractions should be to multiply every term by the least common denominator to clear the fractions, thus clearing grouping symbols. A Nice Efficient Solution Multiply each term by the least common denominator, 12x. Next simplify each expression. Once you’ve cleared the grouping symbols, you’re much more likely to be able to solve the problem. In this case, we’ll transpose, subtracting 3x from each side of the equation. Finally , we’ll divide each side by 7 to get, A Messy Solution that Invites Error I’ve often seen students tackle problems like this by treating the expressions on each side of the equal sign as inviolate. That is, many students begin by adding: This might work out alright for you in the end—there’s certainly nothing in these operations—but it’s just not very useful. Another Solution that’s Not Quite As Messy The same is true to a lesser extent for the method that begins by transposing to isolate the x term: If you followed this step by immediately clearing the fractions, no harm done. Unfortunately most people who begin this way instead proceed to simplify the left hand side of the equation: Again, this could work out alright, but a surprisingly large number of people who start this way choose answer TakeAways
4. Little Texas Drilling Company has three wells, each producing oil at a constant rate. Well A produces one barrel every two minutes. Well B produces one barrel every three minutes. Well C produces one barrel every four minutes. How many hours does it take Little Texas Drilling Company to produce 195 barrels of oil? (A) 2 (B) 3 (C) 4 (D) 18 (E) 180 Show Answer and Explanation Word Problems All the problems we’ve so far considered have presented as algebra. However, quite a few word problems translate into algebraic equations with fractions. In particular, some of the hardest workrate problems become very easy if you can correctly translate them into algebraic equations with fractions, and then correctly solve those equations. A combined rate problem that asks about simultaneous action allows a nice shortcut. If every worker starts and stops at the same time or is working continuously for the duration of the story, we can simply add the various work rates together to determine the combined work rate. Be sure to express work rates as work/time, and be careful to use the same units throughout the problem. In this case, the rate for Well A is 1/2 (one barrel/two minutes), for Well B 1/3, and for well C 1/4. The combined rate is 195 barrels in x hours, which we can express as 60x minutes. All that remains is to solve for x. Multiply through by 60x to clear the fractions. 30x + 20x + 15x = 195 Combine like terms. 65x = 195 And divide each side of the equation by 65. x = 3 The answer, therefore, is (B). (A) statement 1 alone is sufficient, but statement 2 alone is not sufficient to answer the question (B) statement 2 alone is sufficient, but statement 1 alone is not sufficient to answer the question (C) both statements taken together are sufficient to answer the question, but neither statement alone is sufficient (D) each statement alone is sufficient (E) statements 1 and 2 together are not sufficient, and additional data is needed to answer the question Show Answer and Explanation System of Equations Things can get a little more complicated in the Data Sufficiency format, because questions in that format often present us with systems of equations. It’s tempting to suppose that the correct answer is D, since the “if” statement provides one equation and each of the numbered statements provides an equation. However, it’s not the case that just any pair of equations yields values for two variables. The rule is that to solve for two (or n) variables requires two (or n) distinct linear equations. In this case, the equation xy=10 is not linear. Let’s suppose that you decided to start with Statement (2). Before solving algebraically for the values of the variables (which approach would require first constructing and then solving a quadratic equation), check whether simple integer values fit both Statement (2) and the “if” equation. After all, the GMAT usually uses pretty manageable values, and there are too many possibilities for the two relevant simple equations. In fact, it looks as though x and y could be 2 and 5. But which is which? Since y x could be either 52 or 25, Statement (2) is not sufficient. Eliminate answers B and D. Statement (1) is more interesting still. In the last post in this series I wrote that when faced with an algebraic equation involving fraction, you should generally multiply through by the least common denominator to clear all the fractions. Questions which ask you for the value of an expression with more than one variable are sometimes exceptions. In this case, for instance, it’s likely easier to solve for y – x directly than for y and x separately. This means that rather than multiply through by 10xy to clear the fractions, we should manipulate the equation to isolate y – x. Cross multiply the terms on the lefthand side of the equation. Multiply each side of the equation by xy to clear the fraction on the lefthand side. It looks as though our question, “What is y – x?”is equivalent to the question, “What is xy?” Since Statement (1) provides and answer to that question, Statement (1) is sufficient. The correct answer is (A). It turns out that many Data Sufficiency problems with systems of equations work just as this one did.

FROM Magoosh Blog: GMAT Math – What Kind of Math is in the Quantitative Section? 
What’s the biggest secret to GMAT math success? It’s simple! Identify and study the correct quantitative concepts, strategize for problem solving, and leave rote memorization at home. As you may already know, the two types of GMAT math problems are Problem Solving and Data Sufficiency, but what are the GMAT math topics you’ll see on test day? And which ones are the most important? The GMAT Quant section consists of 31 questions in 62 minutes. It’s an adaptive test, meaning that if you correctly answer a few questions, then the next one may be more difficult. Don’t let that worry you though! This is just how the test finds your math ability level. Furthermore, you’ll never encounter any questions that require more than a basic high school understanding of quantitative concepts. Generally speaking, the GMAT Quant section tests your abilities to analyze and problemsolve rather than any advanced knowledge of mathematics. Emphasis is placed on data interpretation, critical reasoning, and word problems. Here’s a great introduction to get you started – Intro to GMAT Math[/*] [/list] What kind of math is on the GMAT?[/*] [*]GMAT Quant Section Breakdown[/*] [*]GMAT Math Tips and Practice Problems[/*] [/list] Problem Solving and Data Sufficiency. Problem Solving problems are by far the more familiar: just work out the question and choose the correct final answer. But Data Sufficiency problems are at a higher level, literally! Instead of seeking an answer to the problem, you have to decide whether there is enough information to answer the problem in the first place. The Four GMAT Math Areas The quantitative knowledge necessary to ace the GMAT consists of basic high school mathematics.

As a result, the percentages in the chart above add up to more than 100%. Here’s a video walking you through the solution.[/list] As you can see, this problem requires nothing but arithmetic and a little bit of critical reasoning. Since it’s a Data Sufficiency problem, don’t worry about trying to solve all the way to a numerical final answer. Instead, let’s go through each of the two statements one by one. First, what is given? There are 42 freshmen and seniors, but we don’t know exactly how many of each. Two unknowns, and one relation (equation). So we are looking for the statement(s) that can help to set up another equation if possible. Statement (1): Be careful, as the wording is tricky here. To say that the group has more than four times as many seniors as freshmen only allows you to set up an inequality (not an equation). It could be that there are zero freshman and 42 seniors, or 8 freshmen 34 seniors, or anything in between. Statement (2): By itself, this doesn’t narrow the field down either. Just saying that there are more than 7 freshmen leaves open all possibilities from 8 to 42 freshmen! But now look again at the conclusions of the two statements. Statement (1) gives you a maximum of 8 freshmen. That’s because 9 freshmen would leave 33 seniors, which is more than four times 9. And Statement (2) gives you a minimum of 8 freshmen (the first whole number more than 7). Thus, together Statements (1) and (2) are sufficient. Answer: C Both are sufficient, but neither one alone is sufficient. Tip #2 — Arithmetic Problems: Use Your Number Sense The key to arithmetic problems is to rely on your number sense and avoid common pitfalls. It takes 1 pound of flour to make \(y\) cakes. The price of flour is \(w\) dollars for \(x\) pounds. In terms of \(w\), \(x\) and \(y\), what is the dollar cost of the flour required to make 1 cake? \(\frac{xy}{w}\) \(\frac{y}{wx}\) \(\frac{w}{xy}\) \(\frac{wx}{y}\) \(wxy\) [/*] Click here for the answer! This is a typical problem dealing with units and ratios. Let’s use our number sense to quickly tackle this one. First, the fact that the price of flour is \(w\) dollars per \(x\) pounds, means that whatever the final answer is, the \(w\) and \(x\) need to be on opposite parts of the fraction. That’s because \(w\) per \(x\) means \(w/x\). So either that, or its reciprocal will be in your final answer. So that narrows it down to just two choices without much work! Either \(\frac{xy}{w}\) or \(\frac{w}{xy}\). Finally, the question is asking for the cost of making one cake. So let’s what happens if we allow \(y\) to vary. Suppose \(y\) is small, like \(y=1\). Then it takes a whole pound of flour to make just 1 cake. But if \(y\) is larger, say \(y=4\), then that same one pound of flour goes much further, bringing the overall cost down per cake. As \(y\) increases, the cost per cake has to decrease. That tells you immediately that \(y\) must be on the bottom of the fraction (in order to get that kind of inverse relationship). Answer: \(\frac{w}{xy}\) See, that wasn’t too hard, right? There are certainly other ways to work this kind of problem out. If you want to see more on this topic, here’s an excellent refresher for GMAT Quant: Rates and Ratios. Tip #3 — Algebra Problems: Try Backsolving or Picking Numbers Common strategies for algebra problems include backsolving and picking numbers. These techniques make it possible to solve a problem without actually solving it. In other words, you can avoid some of the heavy lifting of algebra if you can leverage the answer choices to your favor. Backsolving works by using the answer choices to work backwards. Often this means plugging in each numerical answer choice into given equations, but it can also sometimes be useful when the answers themselves are equations. Line \(k\) is in the rectangular coordinate system. If the \(x\)intercept of \(k\) is \(–2\), and the \(y\)intercept is 3, which of the following is an equation of line \(k\)? \(–3x + 2y = 6\) \(3x + 2y = –6\) \(3x – 2y = 6\) \(2x – 3y = 6\) \(–2x – 3y = 6\) [/*] Click here for the answer! The usual way you’d have to work this out in a high school math class would be to use a formula that gets you the equation of a line from the given intercepts. But we don’t have to remember any kind of formula if you simply backsolve from the answer choices. Take each answer in turn and see if it works. Very quickly you’ll see that \(3x + 2y=6\) has the correct intercepts, and so it solves the problem! Answer: \(3x + 2y=6\) Picking numbers is precisely that! It’s when you pick values for some or all of the variables in a problem, and work the problem with your choices. This often requires you to plug in your numbers into answer choices or Data Sufficiency statements to help eliminate choices. If \(3xm + 2ym − 2yn − 3xn = 0\) and \(m ≠ n\), then what is the value of \(y\) in terms of \(x\)? \(–\frac{2x}{3}\) \(–\frac{3x}{2}\) \(\frac{3x^2}{2}\) \(\frac{2x}{3}\) \(\frac{3x}{2}\) [/*] Click here for the answer! Want to avoid the algebra? Let’s pick some convenient numbers for the variables. Keep in mind that \(m \neq n\). So, let’s start with \(m=2\) and \(n=1\). Plugging those into the given equation, we get: \(6x + 4y – 2y – 3x = 0\), which simplifies to: \(3x + 2y = 0\) Now we could even plug in a number for \(x\) and work out \(y\) from that (to compare with the answer choices), but there’s no need on such a simple equation. \(2y = 3x \implies y = \frac{3x}{2}\) Answer: \(\frac{3x}{2}\) Tip #4 — Geometry Problems: Be Goal Oriented The hardest part about geometry problems is just knowing where to start. It helps to identify the goal and then try to work to fill in the gaps from your given information toward the goal. Think about these questions as you work out geometry questions on the GMAT Math section: What information do I have? Where do I need to end up? What info would be useful to bridge the gap? Are there any formulas that could help? In the diagram, JKLM is a square, and P is the midpoint of KL. Is JQM an equilateral triangle? (1) \(∠KPQ = 90°\) (2) \(∠JQP = 150°\) A. Statement (1) ALONE is sufficient, but Statement (2) alone is not sufficient to answer the question asked. B. Statement (2) ALONE is sufficient, but Statement (1) alone is not sufficient to answer the question asked. C. Both Statements (1) and (2) TOGETHER are sufficient to answer the question asked; but NEITHER statement ALONE is sufficient. D. EACH statement ALONE is sufficient to answer the question. E. Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data specific to the problem are needed. [/*] Click here for the answer! What is given? JKLM is a square; P is the midpoint of KL. Where do I need to end up? Determining whether triangle JQM is equilateral or not. What info would be useful? Knowing all the angles, of course! Helpful formulas? We’ll probably need the fact that all angles in a triangle add to 180 degrees and properties of parallel lines cut by a transversal, because frankly those concepts seem to be important in almost every one of these kinds of problems. Let’s look at Statement (1). If angle KPQ is 90 degrees, then PQ would be parallel to KJ. That’s a great start, but doesn’t give enough info by itself to solve the problem. For instance, the angle JQM would vary depending on how long PQ is. Now consider Statement (2). By itself, having angle JQP is nice, but just not sufficient. What if point Q is left or right of the midline? We’d have no definite way of finding the angles of triangle JQM. However, if both Statements (1) and (2) are taken together, then you have KJ parallel to PQ, and angle JQP = 150. Then angle KJQ is equal to 30 (sameside interior angles). That makes angle MJQ equal to 60. But then because PQ is centered on the midline of the square, the other side is a perfect mirror image. And that gives you angle JMQ — 60 degrees as well. Finally, angle JQM must also be 60, and the triangle is guaranteed to be equilateral! Answer: C Both Statements (1) and (2) TOGETHER are sufficient to answer the question asked; but NEITHER statement ALONE is sufficient. Tip #5 — Word Problems: Don’t Get Lost! Word problems tend to overlap with the other categories. These kinds of problems test your ability to assess a given situation, set up proper steps, choose the correct mathematical tools to solve the problem, and finally to obtain the best answer (or determine if it’s possible to do so, in the case of Data Sufficiency questions). It’s crucial that you don’t get lost. When you read a long word problem, jot some things down as you go. Pay attention to constants and constraints given in the problem. And identify your goal. When a large municipal water tank is empty, it takes a Type JQ pump, working alone, 72 hours to fill the tank, whereas as Type JT pump, working alone, would take only 18 hours to fill the tank completely. If the tank starts at half full, how long would it take two Type JQ pumps and a Type JT pump, all three pumps working together, to fill the tank? 4 6 9 12 24 [/*] Click here for the answer! Both are sufficient, but neither one alone is sufficient. There’s a lot to keep track of here, and some info is just not that important. For example, you don’t need to know that one pump is a “JQ” and other other is a “JT” pump, just that there are two types and they run at different rates. They could have been called “A” and “B” or “1” and “2” for all we care. But it is a good idea to jot down “JQ” and “JT” on your scratch paper to start organizing the rest of the data. The JQ pump fills the tank in 72 hours. How much water is that? We don’t know. But you can say it’s 1 tank worth. So write “1 tank in 72 hrs.” in your JQ column. Similarly, put “1 tank in 18 hrs.” in your JT column. Now, it goes on to ask about filling up a halffull tank. So, alone the JQ would take 36 hours. But we have two JQ’s, which by themselves would cut that fill time to 18 hours. Finally, the trickiest part, what happens when you add in the JT? By itself, it takes 9 hours to fill half the tank. Let’s bring in our number sense. Every time unit, the JQ’s are going to fill only half as much water as the JT, because the JT is pumping twice as fast. When the tank fills, twothirds of the water was pumped in by the JT, and only a third of it by the two JT pumps. So either way you look at it, 6 hours are needed — either one third of 18 hours, or 2/3 of 9 hours. Answer: 6 Wrapping it All Up So now you know what topics to expect on the GMAT Math section! A few final words of advice: Know your fundamentals. Don’t try to do everything in your head, but instead write out your scratch work during the test. Lastly, be sure to get in plenty of practice, and learn from your mistakes. Official tests can be found here: Official GMAT Prep Tests 3 and 4. Good luck on test day!

NOTE: when you do Magoosh practice questions, do not select individual topics that are familiar. When you learn a particular lesson, resist the urge to practice that material right there and then. This plan is based on the philosophy that you should see a random mix of topics every time you practice as you move through the OG. Yes, this means you will make some mistakes in the beginning, especially with topics you haven’t learned thoroughly yet, but if you study those mistakes carefully, that will prime your mind for understanding these ideas more deeply when you get to them in the lessons. Getting questions wrong at the beginning may seem frustrating, but remember that you are playing a “longer game”: the point is not instant success at the beginning, but building deeper understanding over time. Also, it’s important to get accustomed as soon as possible to the random mix of topics you will see, one after the other, on test day. 4) Watch the following Magoosh videos: Under the Intro to the GMAT section:

FROM Magoosh Blog: What’s Tested on the GMAT Verbal Reasoning Section? 
The GMAT Verbal section consists of 36 multiplechoice questions. Each question presents you with five answer choices. You’ll be tested on three areas: Reading Comprehension, Critical Reasoning, and Sentence Correction. Want to learn more? Start with this video – Intro to the GMAT: The Verbal Section[/*] [/list] How long is the GMAT Verbal? What is the timing of each Verbal section? The total time for GMAT Verbal is 65 minutes. With 36 GMAT Verbal questions to contend with, you’ll have between one to three minutes to complete each question, so pacing yourself is key! Here’s what we suggest for timing for GMAT Verbal:
What are the GMAT Verbal questions? Reading Comprehension These questions start with reading a passage about social sciences, physical or biological sciences, or business. Luckily, you don’t have to be an expert in these topics before taking GMAT Verbal. There are six question categories, from finding the main idea of the passage to identifying the author’s tone. To prepare for this question type, check out How to Study for Reading Comprehension. Critical Reasoning Critical Reasoning questions also start with a passage, but this time you’ll be analyzing an argument—specifically, which answer choice makes the argument stronger, weaker, flawed, and more. There are eight question categories. For a breakdown of this question type and categories (plus additional practice!), read our Introduction to Critical Reasoning article. Sentence Correction Instead of a passage, you’ll see just one sentence with an underlined phrase. Your task will be to replace the underlined portion with an answer choice that makes the most sense grammatically or logically. To try this out on your own, see these top grammar tips for Sentence Correction questions. The Basics of GMAT Verbal Scores The max score you can achieve for GMAT Verbal is 800. This will be combined with your GMAT Quant score (also out of 800), and the average of the two forms your overall GMAT score. If you’re not sure how you’d do on Verbal, you can get a baseline score by taking a diagnostic test. After taking steps to improve your score, you can retake the diagnostic test later to measure your progress, and find any remaining weak spots to focus on. Once you have an estimated Verbal and Quant score, you can plug them into a GMAT score calculator to see if you’re close to reaching your target score. How do I prepare for the GMAT Verbal? With the GMAT Verbal score counting towards one of the more important scores that business school admissions consultants are looking at, make sure you’re prepared to see the three types of questions on test day. If this all sounds like a lot, don’t worry! We’ve compiled our practice questions and top tips to help you get ready.

FROM Magoosh Blog: GMAT Analytical Writing: All About the GMAT Essay and How to Prepare For It 
Yup, the rumors are true: you’ll encounter a 30minute GMAT analytical writing section on test day. But while analytical writing can seem tough at first, finding out exactly what’s expected and how to attack it for a maximum score will do a lot to make the GMAT essay feel manageable! In this post, we’ll take a look at what you need to know to master the GMAT AWA. Introduction to GMAT Analytical Writing[/*] [*]What to Expect for GMAT Analytical Writing[/*] [*]How to Approach the GMAT AWA (Strategy and Tips)[/*] [*]Breakdown by Section[/*] [*]Example GMAT Essays[/*] [*]Scoring for GMAT Analytical Writing[/*] [*]GMAT AWA and Business School[/*] [/list] The first bullet point tells us: a good AWA essay is wellorganized, has a natural flow from point to point, and is clear and unambiguous about what it is saying. Those are all important points to keep in mind. The second bullet point reminds us: what they present will be, in all likelihood, a flawed argument, but what you must create is a cogent and clear argument, and that will necessarily involve providing clear and relevant support. It’s not enough simply to assert something badly: you must provide justification for what you are saying. The final bullet points may appear enigmatic: “control the elements of standard written English.” What does that mean? Well, first of all, it means no grammar or syntax mistakes. It also means varying the sentence structure—some simple sentences (noun + verb), some with two independent clauses (noun + verb + and/but/or + noun + verb), some with dependent clauses, some with infinitive phrases, some with participial phrases, etc. Finally, it means choosing the right words and the right tone: the tone should be skeptical toward the prompt argument and persuasive toward the points you are making, but not arrogant or dogmatic in any way. The following paragraph always appears after the argument prompt. This is the real meatandpotatoes of the AWA directions: First of all, notice it give you one clear task: “Be sure to analyze the line of reasoning and the use of evidence in the argument.” Then, it lists several strategies that you might employ in your analysis. Don’t feel compelled to use every one of these in every AWA essay, though you should be using most of them in most essays. Recognizing assumptions is essential for the Critical Reasoning questions, and it will also serve you well on attacking the prompt argument in your AWA. [/*] [*]Know the Directions: This a matter not only of knowing what they say but also, more importantly, understanding the various options you have for analyzing the argument. This list of analytical strategies is always given in the paragraph that follows the prompt argument. It’s important to get familiar with this “analytical toolbox”, so it is yours to employ on test day.[/*] [*]Recognize the Common Flaw Patterns: GMAT AWA prompt arguments often contain one of six types of flaws. Learn to spot these patterns, so you are ready on test day.[/*] [*]Plan Before You Write: This is obvious to some testtakers. Your first task is to find objections to and flaws in the prompt argument. Create a list of flaws. Then, select the 24 of those that are most relevant, that would be the most persuasive talking points. Once you have your list of insightful flaws, then you are ready to write.[/*] [*]Use a Template: Many test takers find it helpful to have the basic structure of the AWA essay already planned out and practiced, so it’s just a matter of plugging in the specific details on test day. Here’s an example of a possible GMAT writing template. Feel free to adapt this template as is, modify it, or create one of your own.
In addition to variety in sentence structure, strive for variety in word choice. Of course, you will want to echo words that appear in the prompt argument. But in your own analysis, vary the descriptive words, never using the same word twice. Don’t say “weak … weak … weak” when you can say “unpersuasive … untenable … questionable.” Wellchosen synonyms can make an essay shine.[*]Avoid Common AWA Errors: There are a few common flaws that can pull your GMAT analytical writing score down. As you practice the AWA, make sure you avoid the following:
AWA brainstorming. As you brainstorm, list the argument’s flaws; then evaluate those flaws to find which objections are the strongest. Write an Introduction You don’t need to reinvent the wheel with each GMAT AWA introduction. Start by stating where the passage is from. Then, focus on two main tasks: summarizing the argument and stating why it’s flawed. Keep it short and sweet; three sentences are enough to get your main points set up! Construct Your Body Paragraphs These will make up the lion’s share of your essay, so you’ll spend most of your time writing body paragraphs. Here’s how to go about doing that:
First of all, keep in mind that you should not dwell in the conclusion. The heart of your essay, what really matters toward your score, is in the body paragraphs. These should be bulky and indepth, but the conclusion should be short and to the point. Wrap things up in a timely manner so that you can get to the business of editing and revising your essay. To keep things manageable and short, don’t go into the details. You only need to recap the major problems in the argument. Sometimes it is enough to say that there are major problems in the argument. Ignore the desire to repeat all the main points that you covered in the body paragraphs. This will only take extra space and waste precious time. Finally, recommend a way to achieve the goal stated in the article. It is important to approach the analysis of the argument as an interested party. You don’t want to be wholly negative. For one, you will write a better analysis if you imagine yourself tied to the argument in some way, and two, the prompt asks you to strengthen the argument. Find some general evidence that will make the argument more convincing or make it irrefutable. Suggest a change so that the logic stands on firmer ground. examples of analytical questions for the GMAT, look no further! Once you’ve read few a through sample AWA prompts, read through the third prompt on page 31 of the PDF. Magoosh GMAT expert Mike McGarry has written a great GMAT AWA Example essay in response to this prompt, including analysis of why it works well and why it would receive a 6. GMAT AWA scoring rubric you can use for this purpose. But if you’re not certain about how your essays measure up to the GMAT scale, there are other ways to get your GMAT essay scored. These include GMAT Write, an official (paid) service from GMAC; friends; and forums. Take a look and see what option works best for you. recent evidence suggest that adcoms also rely on the IR score significantly more than the GMAT essay score. But while it’s true that, in your GMAT preparation, Quant and Verbal and even IR deserve more attention than the AWA, it’s also true you can’t completely neglect AWA. The difference between a 5 or 6 as your GMAT Analytic Writing score will not make or break a business school admission decision, but having an essay score below a 4 could hurt you. The purpose of the AWA is to see how well you write, how effectively you express yourself in written form. This is vital in the modern business world, where you may conduct extensive deals with folks you only know via email and online chatting. Some of your important contacts in your business career will know you primarily through your writing, and for some, your writing might be their first experience of you. You never get a second chance to make a first impression, and when this first impression is in written form, the professional importance of producing highquality writing is clear. While you don’t need to write like Herman Melville, you need to be competent. A GMAT Analytic Writing score below 4 may cause business schools to question your competence. That’s why it’s important to have at least a decent showing in AWA. For NonNative English Speakers In particular, if English is not your native language, I realize that this makes the AWA essay all the more challenging, but of course, a solid performance on the AWA by a nonnative speaker would be a powerful testament to how well that student has learned English. Toward this end, nonnative speakers should practice writing the AWA essay and try to get highquality feedback on their essays. Devoting 30% or more of your available study time to AWA is likely unwise, but devoting 0% to AWA might also hurt you. Between those, erring on the low side would be appropriate. If, in a threemonth span, you write half a dozen practice essays, and get generally positive feedback on them with respect to the GMAT standards, that should be plenty of preparation. Conclusion The GMAT analytical writing can feel like a slog when you first encounter it: it requires deep focus and analysis, and it’s not what most students have spent their prep time working on. But with a bit of preparation, your GMAT essays can take your admissions file to the next level by boosting your AWA score significantly! By including GMAT writing in your overall GMAT prep schedule, you’ll ensure that this section of the test doesn’t become a drag on your application—and helps, rather than hurts, your shot at your dream school.

Write an Introduction You don’t need to reinvent the wheel with each GMAT AWA introduction. Start by stating where the passage is from. Then, focus on two main tasks: summarizing the argument and stating why it’s flawed. Keep it short and sweet; three sentences are enough to get your main points set up! Construct Your Body Paragraphs These will make up the lion’s share of your essay, so you’ll spend most of your time writing body paragraphs. Here’s how to go about doing that:
First of all, keep in mind that you should not dwell in the conclusion. The heart of your essay, what really matters toward your score, is in the body paragraphs. These should be bulky and indepth, but the conclusion should be short and to the point. Wrap things up in a timely manner so that you can get to the business of editing and revising your essay. To keep things manageable and short, don’t go into the details. You only need to recap the major problems in the argument. Sometimes it is enough to say that there are major problems in the argument. Ignore the desire to repeat all the main points that you covered in the body paragraphs. This will only take extra space and waste precious time. Finally, recommend a way to achieve the goal stated in the article. It is important to approach the analysis of the argument as an interested party. You don’t want to be wholly negative. For one, you will write a better analysis if you imagine yourself tied to the argument in some way, and two, the prompt asks you to strengthen the argument. Find some general evidence that will make the argument more convincing or make it irrefutable. Suggest a change so that the logic stands on firmer ground. examples of analytical questions for the GMAT, look no further! Once you’ve read few a through sample AWA prompts, read through the third prompt on page 31 of the PDF. Magoosh GMAT expert Mike McGarry has written a great GMAT AWA Example essay in response to this prompt, including analysis of why it works well and why it would receive a 6. GMAT AWA scoring rubric you can use for this purpose. But if you’re not certain about how your essays measure up to the GMAT scale, there are other ways to get your GMAT essay scored. These include GMAT Write, an official (paid) service from GMAC; friends; and forums. Take a look and see what option works best for you. recent evidence suggest that adcoms also rely on the IR score significantly more than the GMAT essay score. But while it’s true that, in your GMAT preparation, Quant and Verbal and even IR deserve more attention than the AWA, it’s also true you can’t completely neglect AWA. The difference between a 5 or 6 as your GMAT Analytic Writing score will not make or break a business school admission decision, but having an essay score below a 4 could hurt you. The purpose of the AWA is to see how well you write, how effectively you express yourself in written form. This is vital in the modern business world, where you may conduct extensive deals with folks you only know via email and online chatting. Some of your important contacts in your business career will know you primarily through your writing, and for some, your writing might be their first experience of you. You never get a second chance to make a first impression, and when this first impression is in written form, the professional importance of producing highquality writing is clear. While you don’t need to write like Herman Melville, you need to be competent. A GMAT Analytic Writing score below 4 may cause business schools to question your competence. That’s why it’s important to have at least a decent showing in AWA. For NonNative English Speakers In particular, if English is not your native language, I realize that this makes the AWA essay all the more challenging, but of course, a solid performance on the AWA by a nonnative speaker would be a powerful testament to how well that student has learned English. Toward this end, nonnative speakers should practice writing the AWA essay and try to get highquality feedback on their essays. Devoting 30% or more of your available study time to AWA is likely unwise, but devoting 0% to AWA might also hurt you. Between those, erring on the low side would be appropriate. If, in a threemonth span, you write half a dozen practice essays, and get generally positive feedback on them with respect to the GMAT standards, that should be plenty of preparation. Conclusion The GMAT analytical writing can feel like a slog when you first encounter it: it requires deep focus and analysis, and it’s not what most students have spent their prep time working on. But with a bit of preparation, your GMAT essays can take your admissions file to the next level by boosting your AWA score significantly! By including GMAT writing in your overall GMAT prep schedule, you’ll ensure that this section of the test doesn’t become a drag on your application—and helps, rather than hurts, your shot at your dream school.

FROM Magoosh Blog: Integrated Reasoning on the GMAT: The Complete Guide 
If you’re sitting down to your first GMAT Integrated Reasoning section, you might not know what to think! You’ll have 30 minutes to answer 12 Integrated Reasoning GMAT questions involving a ton of data analysis, critical thinking, and quantitative reasoning. But by preparing early—and thoroughly!—you’ll be able to get the Integrated Reasoning GMAT score that you want on test day. What is GMAT Integrated Reasoning? The GMAT Integrated Reasoning section tests your quantbased and verbalbased reasoning in 4 parts: multisource reasoning, table analysis, twopart analysis, and graphics interpretation. Essentially, the GMAT IR section is testing for your data analysis skills. The big question for many students: just what is the GMAT IR score importance? IR is relatively important (and increasingly so!), so it’s vital not to ignore it! Overall, you can expect to see 12 questions in 30 minutes. It’s not quite as simple as it sounds, though: each graph or prompt will have multiple questions. In addition, you’ll have to answer a question before you can move on—and you can’t go back to a question once you’ve answered it. Check out this video of Magoosh’s Introduction to Integrated Reasoning lesson! Integrated Reasoning Question Types on the GMAT MultiSource Reasoning Multisource reasoning questions show you a split screen: on the left, you’ll have three clickable cards, each with a piece of information that will help you answer a particular question, and which you can only see one of at a time. The questions are either standard fivechoice multiple choice or multiple dichotomous choice. You’ll have two answer choices (e.g. “true/false”) for each part of a threepart question. For more sample multisource reasoning problems, click here! Table Analysis Table analysis questions give you a sortable table of numbers. These are accompanied by multiple dichotomous choice questions, in which you have two answer choices (e.g. “true/false”) for each part of a threepart question. Check out a sample table analysis problem! Graphics Interpretation For graphics interpretation questions, you’ll receive some visual information in the form of a chart or a graph, then questions containing two dropdown menus each. These menus will have you fill in blanks within a sentence according to the data shown in the visual. Check out more sample graphics interpretation problems! TwoPart Analysis Twopart analysis questions give you a large prompt, followed by a questionandanswer table. You will fill out the answers for each of two questions, which can vary; they may be partially or completely related, but they will always be interdependent. Check out a sample twopart analysis problem! Strategies for Getting a Good Integrated Reasoning GMAT Score Getting a good Integrated Reasoning GMAT score can be tricky—not least of all because a lot of people aren’t sure what a good IR score is! Unlike the total GMAT score, which is scored between 200 and 800, IR is scored between 1 and 8. Most people would consider a good score to be above the 50th percentile—in other words, better than half of testtakers’ scores. For IR, this is a 5 or higher. So how do you get that good score of 5+ on GMAT IR? Here are a few keys to succeeding:
Need Integrated Reasoning GMAT practice? You’re not alone! That’s why Magoosh is excited to present you with the ultimate GMAT Integrated Reasoning eBook: Magoosh’s Complete Guide to GMAT Integrated Reasoning!

You may love GMAT word problems or you may hate them, but you can’t get around them if you want to ace the GMAT Quant section. No matter what your feelings are about this problem type, though, Magoosh’s experts have put together everything you need to know (and practice!) GMAT word problems in order to master them before test day. What to Expect from GMAT Word Problems[/*] [*]Strategy Guide: What’s the Trick to Mastering GMAT Word Problems?
GMAT Quant section. How much of the GMAT is word problems? Within the Quant section, actually a whole lot! A study of official GMAT questions from actual tests show that word problems account for 58.2% of all GMAT math questions. In other words, testtakers should anticipate a word problem cropping up (on average) in three out of every five questions you’ll see in Quant. Because of GMAT word problems’ prevalence, you can expect to see both Data Sufficiency and Problem Solving questions in this format. The question format and answer choices may look different, but the basic premise will be the same. You may be feeling the pressure, but hang in there! If you’re worried about how to master word problems on the GMAT, keep reading for our GMAT Word Problems strategy guide. Variables in GMAT Answer Choices: 2 Approaches. tips for plugging in numbers that you should use! Here’s a quick summary of how to quick the best numbers for a particular problem:
Click here for a video answer and explanation to GMAT Word Problem 1![/b] Click here for a text answer and explanation to GMAT Word Problem 1! Our task is to determine the ratio of Bob’s trees to Ann’s trees. Let’s label these numbers of trees with variables: Bob’s trees→B, Ann’s trees→A With these variables, we can express the ratio we want to determine: \(B/A\) =? Statement 1: Ann planted 20 trees more than Bob planted. Let’s translate this into an equation using A and B: \( A=B+20 \) Now we can substitute this into our ratio, replacing A: \(B/A\) = \( B/(B+20) \) No matter what simplifications we make, we cannot find a numerical value for this fraction. We would need a value for B. We cannot determine the ratio. Statement 1 by itself is not sufficient. Statement 2: Ann planted 10 percent more trees than Bob planted. Let’s translate this into an equation using A and B: \(A=1.10 x B \) Again, let’s substitute this in for A in our ratio: \(B/A\) = \( B/(1.10B) \) = \(1/1.1 \) We found a value for the ratio of Bob’s trees to Ann’s trees. Statement 2 alone is sufficient. [*]The Townville museum was open for 7 consecutive days. If the number of visitors each day was 3 greater than the previous day, how many visitors were there on the first day? (1) There were a total of 126 visitors for the 7 days. (2) The number of visitors on the seventh day was three times the number of visitors on the first day. [/list] A. Statement 1 ALONE is sufficient to answer the question, but statement 2 alone is NOT sufficient. B. Statement 2 ALONE is sufficient to answer the question, but statement 1 alone is NOT sufficient. C. BOTH statements 1 and 2 TOGETHER are sufficient to answer the question, but NEITHER statement ALONE is sufficient. D. Each statement ALONE is sufficient to answer the question. E. Statement 1 and 2 TOGETHER are NOT sufficient to answer the question. Click here for a video answer and explanation to GMAT Word Problem 2! Click here for a text answer and explanation to GMAT Word Problem 2! If x is the number of visitors on the first day, then: x = # of visitors on the 1st day x + 3 = # of visitors on the 2nd day x + 6 = # of visitors on the 3rd day x + 9 = # of visitors on the 4th day x + 12 = # of visitors on the 5th day x + 15 = # of visitors on the 6th day x + 18 = # of visitors on the 7th day 1) Adding up the number of visitors gives us: x + (x + 3) + (x + 9) + (x + 12) + (x + 15) + (x + 18) = 126 We could simplify and solve this for x. So Statement 1 is sufficient. 2) x + 18 = 3x Again, we can simplify this and solve for x. So Statement 2 is sufficient. Answer: (D) [*]Two teachers, Ms. Ames and Mr. Betancourt, each had N cookies. Ms. Ames was able to give the same number of cookies to each one of her 24 students, with none left over. Mr. Betancourt was also able to give the same number of cookies to each one of his 18 students, with none left over. If N > 0, what is the value of N? (1) N<100 (2) N > 50 [/list] A. Statement 1 ALONE is sufficient to answer the question, but statement 2 alone is NOT sufficient. B. Statement 2 ALONE is sufficient to answer the question, but statement 1 alone is NOT sufficient. C. BOTH statements 1 and 2 TOGETHER are sufficient to answer the question, but NEITHER statement ALONE is sufficient. D. Each statement ALONE is sufficient to answer the question. E. Statement 1 and 2 TOGETHER are NOT sufficient to answer the question. Click here for a video answer and explanation to GMAT Word Problem 3! Click here for a text answer and explanation to GMAT Word Problem 3! This question is really about common multiples and the LCM (note that it is different than finding the set of all multiples, though!). If Ms. Ames can give each of her 24 students k cookies, so that they all get the same and none are left over, then 24k = N. Similarly, in Mr. Betancourt’s class, 18s = N. What are the common multiples of 18 and 24? 18 = 2×9 = 2×3×3 = 6×3 24 = 3×8 = 2×2×2×3 = 6×4 From the prime factorizations, we see that GCF = 6, so the LCM is LCM = 6×3×4 = 72 and all other common multiples of 18 and 24 are the multiples of 72: {72, 144, 216, 288, 360, …} Statement #1: if N<100, the only possibility is N = 72. This statement, alone and by itself, is sufficient. Statement #2: if N > 50, then N could be 72, or 144, or 216, or etc. Many possibilities. This statement, alone and by itself, is not sufficient. Answer = (A) [*]A certain zoo has mammals and reptiles and birds, and no other animals. The ratio of mammals to reptiles to birds is 11:8:5. How many birds are in the zoo? (1) there are twelve more mammals in the zoo than there are reptiles (2) if the zoo acquired 16 more mammals, the ratio of mammals to birds would be 3:1 [/list] A. Statement 1 ALONE is sufficient to answer the question, but statement 2 alone is NOT sufficient. B. Statement 2 ALONE is sufficient to answer the question, but statement 1 alone is NOT sufficient. C. BOTH statements 1 and 2 TOGETHER are sufficient to answer the question, but NEITHER statement ALONE is sufficient. D. Each statement ALONE is sufficient to answer the question. E. Statement 1 and 2 TOGETHER are NOT sufficient to answer the question. Click here for a video answer and explanation to GMAT Word Problem 4! Click here for a text answer and explanation to GMAT Word Problem 4! A short way to do this problem. The prompt gives us ratio information. Each statement gives use some kind of count information, so each must be sufficient on its own. From that alone, we can conclude: answer = D. This is all we have to do for Data Sufficiency. Here are the details, if you would like to see them. Statement (1): there are twelve more mammals in the zoo than there are reptiles From the ratio in the prompt, we know mammals are 11 “parts” and reptiles are 8 “parts”, so mammals have three more “parts” than do reptiles. If this difference of three “parts” consists of 12 mammals, that must mean there are four animals in each “part.” We have five bird “parts”, and if each counts as four animals, that’s 5*4 = 20 birds. This statement, alone and by itself, is sufficient. Statement (2): if the zoo acquired 16 more mammals, the ratio of mammals to birds would be 3:1 Let’s say there are x animals in a “part”—this means there are currently 11x mammals and 5x birds. Suppose we add 16 mammals. Then the ratio of (11x + 16) mammals to 5x birds is 3:1. (11x + 16)/(5x) = 3/1 = 3 11x + 16 = 3*(5x) = 15x 16 = 15x – 11x 16 = 4x 4 = x So there are four animals in a “part”. The birds have five parts, 5x, so that’s 20 birds. This statement, alone and by itself, is sufficient. Both statements are sufficient. Answer = D. average speed to total distance traveled, from total time to total amount.

FROM Magoosh Blog: GMAT Error Log: The Key to GMAT Success (Free Template Included) 
Your GMAT journey will be both challenging and rewarding. You will have highs and lows. There will be days that will build your confidence and then other days you will want to forget about completely. We have all had those days: you are studying and you feel like you can’t get any question right. But before you crumble up that paper, wipe clean that dry erase board, or power down that computer, STOP! Document your struggles and capture that data! Why Keeping an Error Log is So Important Our mistakes are chock full of information about our test taking abilities, strategies, and more importantly, our habits. Whether you’re GMAT studying for the first time or preparing for a retake, a critical look at how we approach, solve, and check our work will not only direct us to which areas we should study next, but will make us conscious about the bad habits we exhibit every time we attempt a GMAT problem. We are always told to review our questions after we complete practice problems and the best way to advance your skills is by using a GMAT Error Log! I know what you’re thinking: not another GMAT wonder tool you have to buy to achieve your goal score. We get it. The GMAT is not only taxing on you mentally, physically, and socially (no one wants to hang out with the guy with Critical Reasoning flashcards at the party), but the GMAT is also COSTLY! That’s the beauty of the GMAT Error Log—it’s a completely free tool! Even better, keep reading and I will share with you a template I use to save you time on finding one online. Yes, the power of self evaluating your GMAT progress can be yours with a few clicks of a mouse! How to Use an Error Log GMAT prep is broken down into three parts: Content, Problem Solving, & Testing. What I have seen that keeps testtakers from earning their top score is that they haven’t spent enough time in the Problem Solving stage. Testtakers would read 100% of the material and complete 4 to 5 practice CAT exams, but would only successfully complete 2030% of all the questions on the Magoosh platform and even less when it comes to the Official Guide. Knowing the ratios of a 306090 triangle, how to FOIL, or what is a noun is important, but you must drill these topics in various various ways to really understand these concepts and how to answer these questions on the exam. Taking CAT exams in isolation will not improve your score. It is in careful review and reflection is where you will develop skills and earn points. CAT exams are a major time investment and are extremely valuable, so you don’t want to waste too much time to only answer 30 or more random questions. What I have seen successful testtakers do is create mini problems sets (5, 8, 10, or 16 questions) and use those as a sample test to gauge their skill set. In these practice problems is where the GMAT Error Log shines! Let’s say each day for a week, you complete 10 to 20 random problems of various question types and difficulties. You are bound to miss a few questions. What most people do when they get a question wrong is read the explanation, say “oh I got it,” and move on. Here is where you leverage the GMAT Error Log. Not only will you read the explanation, you will also input the question you got wrong in the Error Log, what you did wrong, and what you will do differently next time. This seems like a small task today, but in the beginning, it can feel very daunting. After about 20 or so questions, though, you will get into the habit of updating your error log and begin to see the fruits of your labor. Leading up to a test day, a great Error Log can be a great review tool right before a CAT exam. When I work with my testtakers I teach them how to build a detailed Error Log with great care because it is those careless errors or habits that are written in the Error Log that jumps your GMAT score from a 620 to 650 or 690 to that 700. How to Structure Your GMAT Log Your Error Log does not need to have many bells and whistles. It doesn’t need to be something with macros and automated graphic generators. It doesn’t have to be a spreadsheet or digital at all. I actually keep two logs – an old school black and white marble notebook and a digital copy. The Error Log just has to fit your method of notetaking and meet your dedication to the process. Error Logs lose value when they are not updated. You only get out of the Error Log what you put in. I can never guarantee your score to improve, but I can say that having a running list of all your mistakes can help prevent you from making them again. Here is the key information you want to have in any GMAT Error Log:
This sounds extremely simple, because it is – the challenging part is sticking to the habit. After a few weeks, you will have an error log that you will cherish and will be excited to fill it up.
