Early Thoughts on Columbia Business School’s 2016-2017 Application Ess [#permalink]
Expert Reply
FROM Veritas Prep Blog: Early Thoughts on Columbia Business School’s 2016-2017 Application Essay Questions

Application season at Columbia Business School is officially underway with the release of the school’s 2016-2017 essay questions. Let’s discuss from a high level some early thoughts on how best to approach these new essay prompts. There are three full essay questions and one shorter prompt for Columbia, which leaves this school with one of the lengthier application packages around.

With all these essays, it is crucial that applicants present their candidacy in a very clear yet non-redundant fashion. Let’s take a look at each of the essay questions Columbia is asking this year:

Goal:

What is your immediate post-MBA professional goal? (50 characters)

Given the tight character limit to this prompt, keep your response here short and sweet. Most of the context you would normally provide in such a response will find a home in your response to Essay 1.

Essay 1:

Through your resume and recommendations, we have a clear sense of your professional path to date. What are your career goals going forward, and how will the Columbia MBA help you achieve them? (100-750 words)


This is basically the same prompt for Essay 1 as last year, but with greater flexibility on the word count, which now spans from 100-750 words as opposed to last year’s 500-word limit. Do not feel it is absolutely necessary to hit the upward bounds of the new word count just because you have the option – efficiency and impactful messaging always reigns supreme in business school essays.

Columbia’s first essay question falls into the typical “career goals” essay category – the key difference here will be a focus on the future and your post-MBA career, so avoid placing too much of an emphasis on your past professional career. Remember, the Admissions Committee will already have your resume and thus, some sense of your past, so avoid rehashing your background (outside of providing any necessary context).

With this in mind, presenting both your short-term and long-term career goals in a well-aligned and clearly articulated way will be key to executing this essay successfully. Probably even more important, (given the ubiquity of your career goals), is the “fit” aspect of the essay. Breakthrough candidates will cite specific references to Columbia’s professional, academic, and extra-curricular programs that will support their development goals. With so much competition between business schools, it is critical to make a strong case that you will fit well with Columbia’s particular MBA program.

Essay 2:

Columbia Business School’s students participate in industry focused New York immersion seminars, in project based Master Classes, and in school year internships. Most importantly, they are taught by a combination of distinguished research faculty and accomplished practitioners. How will you take advantage of being “at the very center of business”? (100-500 words)


Columbia comes back this year with a slight tweak to Essay 2 with the ultimate prompt effectively being the same. Columbia is uniquely positioned at the heart of business in NYC, which has lured many applicants to this top program for years. Use this essay as an opportunity to avoid generalities about NYC that other applicants may make, and get specific about how Columbia’s unique location in NYC will serve as a clear advantage in your personal and professional career, and specifically during your time on campus. This essay can also be used to build upon your response to Essay 1. 

Essay 3:

CBS Matters, a key element of the School’s culture, allows the people in your Cluster to learn more about you on a personal level. What will your Clustermates be pleasantly surprised to learn about you? (100-250 words)


This question is a great chance to let your personality shine through. This is the shortest of the three full essays so every word counts – take advantage of this more open essay prompt and really try and give the Admissions Committee some “behind the scenes” insight into the type of person your classmates will meet in the Fall of 2017.  Use this essay as the platform to differentiate yourself, and remember to keep your tone light and authentic to give the school a better understand of who you are and how you will fit as a member of their incoming MBA class.

Just a few thoughts on the (not so) new batch of essays from Columbia Business School – hopefully this will help you get started with your own application. For more thoughts on Columbia and its application essays, check out our Essential Guide to Top Business Schools for free, here.

How to Reach a 99th Percentile GMAT Score Using No New Academic Strate [#permalink]
Expert Reply
FROM Veritas Prep Blog: How to Reach a 99th Percentile GMAT Score Using No New Academic Strategies

Last week I received an email from an old student who’d just retaken the GMAT. He was writing to let me know that he’d just received a 770. Of course, I was ecstatic for him, but I was even more excited once I considered what his journey could mean for other students.

His story is a fairly typical one: like the vast majority of GMAT test-takers, he enrolled in the class looking to hit a 700. His scores improved steadily throughout the course, and when he took the test the first time, he’d received a 720, which was in line with his last two practice exams. After he finished the official test, he called me – both because he was feeling pretty good about his score but also because a part of him was sure he could do better.

My feeling at the time was that there really wasn’t any pressing need for a retake: a 720 is a fantastic score, and once you hit that level of success, the incremental gains of an improvement begin to suffer from the law of diminishing returns. Still, when you’re talking about the most competitive MBA programs, you want any edge you can get. Moreover, he’d already made up his mind. He wanted to retake.

Part of his decision was rooted in principle. He was sure he could hit the 99th percentile, and he wanted to prove it to himself. The problem, he noted, was that he’d already mastered the test’s content. So if there was nothing left for him to learn, how did he jump to the 99th percentile?

The answer can be found in the vast body of literature enumerating the psychological variables that influence test scores. We like to think of tests as detached analytic tools that measure how well we’ve mastered a given topic. In reality, our mastery of the content is one small aspect of performance.

Many of us know this from experience – we’ve all had the experience of studying hard for a test, feeling as though we know everything cold, and then ending up with a score that didn’t seem to reflect how well we’d learned the material. After I looked at the research, it was clear that the two most important psychological variables were 1) confidence and 2) how well test-takers managed test anxiety. (And there’s every reason to believe that those two variables are interconnected.)

I’ve written in the past about how a mindfulness meditation practice can boost test day performance. I’ve also written about how perceiving anxiety as excitement, rather than as a nefarious force that needs to be conquered, has a similarly salutary effect. Recently I came across a pair of newer studies.

In one, researchers found that when students wrote in their journals for 10 minutes about their test-taking anxiety the morning of their exams, their scores went up substantially. In another, the social psychologist Amy Cuddy found that body language had a profound impact on performance in all sorts of domains. For example, her research has revealed that subjects who assumed “power poses” for two minutes before a job interview projected more confidence during the interview and were better able to solve problems than a control group that assumed more lethargic postures. (To see what these power poses look like, check out Cuddy’s fascinating Ted talk here.) Moreover, doing power poses actually created a physiological change, boosting testosterone and reducing the stress hormone Cortisol.

Though her research wasn’t targeted specifically at test-takers, there’s every reason to believe that there would be a beneficial effect for students who practiced power poses before an exam. Many teachers acquainted with Cuddy’s research now recommend that their students do this before tests.

So the missing piece of the puzzle for my student was simply confidence. His strategies hadn’t changed. His knowledge of the core concepts was the same. The only difference was his psychological approach. So now I’m recommending that all of my students do the following to cultivate an ideal mindset for producing their best possible test scores:

  • Perform mindfulness meditation for the two weeks leading up to the exam.
  • Reframe test-day anxiety as excitement.
  • Spend 10 minutes the morning of the test writing in a journal.
  • Practice two minutes of power poses in the waiting room before sitting for the exam and between the Quant and Verbal section.

SAT Tip of the Week: Remember That the Test is Standardized [#permalink]
Expert Reply
FROM Veritas Prep Blog: SAT Tip of the Week: Remember That the Test is Standardized

The SAT, as all of you know, is a whole different animal compared to most tests you take. In terms of time, content, and structure, it’s definitely not your average high school exam. While this difference can serve to make the SAT seem particularly difficult, it can actually be a boon to test takers.

Whereas high school tests operate by their own rules and procedures that vary class-by-class and school-by-school, the SAT is by definition a standardized test. And although standardized tests are usually thought of as a drag, in this case standardization makes taking the SAT a lot easier.

Since the SAT is standardized, it has to operate the same way every time – it always plays by the same rules, always has similar types of questions, always has the same instructions, and so on. How is this information helpful to a test taker? Here are three ways to use this knowledge to your advantage:

1) There are no surprises.

Since the SAT has to operate by the same rules on each of its versions, you know what you’re going to get on each exam. There are limited and delineated areas of content, so there’s no chance a question on advanced calculus will show up on your test. Keeping this consistency in mind can help alleviate some stress about the SAT, since you know that if you’ve studied hard, you’ll be prepared for anything the College Board throws at you.

2) Answer choices have to be totally and completely defensible.

Since the test is strictly standardized, there can only be one right answer on each question. Let me say that again: there can only be one right answer per question! No other answer choice besides the right one can be at all correct. If there were answers that were debatable or questionable, then the standardization mechanism of the test would fall apart – there would be no way for the College Board to definitively say who scored better or worse if some questions had two answer possibilities.

So, when taking the test, know that if you find yourself stuck between two answer choices, then you’re thinking about the question wrong in some way. While it can be hard on the ego to admit this, it will help you re-frame these difficult questions in your head and be more confident in your ultimate answers. 

3) Practice really can make perfect (or at least better).  

Going along with the first point, since you know what general questions are going to be on the test, you can know that you are practicing the right things. Unlike some high school tests where you spend days studying only to realize the test isn’t what you thought it was going to be, on the SAT, the real tests will look exactly like the practice tests. So, the more you practice, the more you’ll be prepared for the real thing – it’s as simple as that!

Instead of thinking of the standardization and repetitiveness of the SAT as annoying, now you can know that it is this exact standardization that makes it easier to succeed on this challenging exam.

Early Thoughts on Wharton’s 2016-2017 Application Essay Questions [#permalink]

FROM Veritas Prep Blog: Early Thoughts on Wharton’s 2016-2017 Application Essay Questions

Application season at the University of Pennsylvania’s Wharton School of Business is officially underway with the release of the school’s 2016-2017 essay questions. Let’s discuss from a high level some early thoughts on how best to approach these new essay prompts. This year Wharton has added an additional required essay question (as opposed to last year’s one required essay and one optional essay).

Essay 1:

What do you hope to gain both personally and professionally from the Wharton MBA? (500 words)

The Wharton School has brought back its “growth” essay again for another year. The biggest potential pitfall in this question is to treat it like a typical “career goals” essay, and I caution against simply recycling your responses to similar essay questions from other programs. This prompt implores candidates to address both their professional and their personal fit with Wharton. Given the many opportunities to explore the professional side of your background throughout the application process, don’t be afraid to put some additional focus on the personal side here.

This prompt is also asking you to think broadly, so don’t minimize your vision. Breakthrough candidates will utilize a very personal narrative that uniquely captures the essence of why Wharton is the ideal fit for the applicant’s development goals. Wharton is looking for specifics here about why their particular school is the best one for you, so avoid general statements that could be harbored by any candidate. The personal element is what makes this question a bit more unique, so consider growth vectors that include others to showcase yourself as the leader a top business school like Wharton is looking for.

Essay 2:

Teamwork is at the core of the Wharton MBA experience with each student contributing unique elements to our collaborative culture. How will you contribute to the Wharton community? (400 words)

This prompt is all about “teamwork” and “impact,” and a successful essay will really align these two elements. Hone in on the unique aspects of your profile that relate to these to showcase how you will make a positive impact on the Wharton community – whether it is through academic, professional, social, or diverse means, think through what you will contribute and how this will positively affect others at Wharton.

Your ability to translate a past teamwork experience to your planned future contributions at Wharton is a good approach for this essay. Past performance will add additional validity to your claims if you can effectively connect the dots for the Admissions Committee. If you can specify which aspects of the Wharton community you will influence, that would be even better. The pillars of the Wharton MBA are clear, so align your narrative around impacting the school’s most important focus areas.

Just a few thoughts on this year’s essays prompts from Wharton – hopefully this will help you get started. For more thoughts on Wharton and its application essays, check out our Essential Guide to Top Business Schools for free, here.

Why Be an Intern? 4 Reasons You Should Consider Getting an Internship [#permalink]
Expert Reply
FROM Veritas Prep Blog: Why Be an Intern? 4 Reasons You Should Consider Getting an Internship

Internships are time consuming, energy consuming, and frequently unpaid. Taking internships often means filling time that might otherwise be spent on classes or extracurricular activities – and spending that time completing low-level work from an organization you likely won’t be affiliated with for more than a few months. So why are they so useful, and why is competition for them often so fierce?

The answer is that the benefits of an internship goes far beyond an intern’s (often boring) day-to-day workload. Here are a few:

1) Insight Into a Career Track

There is no better way to learn whether a career track is right for you – or whether a particular field is right for you – than to observe and meet people who are in it, and to be in it yourself. Often, interns gain just as much, if not more, from shadowing and observing company staff as they do from completing their own assignments.

2) Connections

Being in a work environment in your desired field means being regularly exposed to professionals in that realm. Internships are great networking opportunities; the connections you make as an intern can potentially open doors to future internships, study and research opportunities, and even job positions after graduation.

3) Resume Boosters

Internships look great on resumes because they show that you haven’t just looked at a subject in theory through classes and textbooks – you’ve tried it out in practice and gained perspective on the practicalities, frustrations, and other everyday realities involved in that line of work. If you continue pursuing positions in that field, whether in the form of more internships or longer-term employment, having an internship on your resume tells potential employers that you understand the work you’re getting into and have useful skills and experience to apply to it.

4) Practice

In nearly every field, working life is very different from student life in terms of hours, expectations, environment, social surroundings, and more. As such, the transition from studying a field to working in it can be a difficult one. Interning helps you to transition more slowly into working life: having fewer responsibilities and less expected of you than other full-time staff will allow you space to learn time management, to adapt to a new rhythm of life and work, and to even make a few mistakes.

How to Address a Low GPA in Your MBA Applications [#permalink]
Expert Reply
FROM Veritas Prep Blog: How to Address a Low GPA in Your MBA Applications

A low GPA’s is one of the foremost concerns among those applying to business school. Even having a GPA that seemed “okay” in undergrad now probably seems a little mediocre if you’re aiming for a top MBA program. And if your GPA is actually low, you’re sure to be even more concerned.

With no way to actually change this aspect of your profile, how can you address your GPA concerns?

1) Present a Strong GMAT Score & Additional Credentials

The best way to mitigate a low GPA is to get a great GMAT score – scoring above the average of your target program will alleviate any potential concerns the Admissions Committee may have about your academic potential to keep pace with the school’s rigorous curriculum. A higher score could boost your chances for admission, and even scholarships. Thus, investing the time, effort, and resources to maximize your potential to score as high as you can on the GMAT makes sense.

Obtaining credentials such as a CFA (Chartered Financial Analyst) title or taking on additional courses at your local community college are also helpful in showing that you will be able to handle the coursework of business school, as well as contribute to, and reap the benefits of, your future class discussions.

2) Provide Context

Sometimes life circumstances – including illnesses, family responsibilities, or competing priorities – can have a negative impact on one’s GPA. If this is the case, the optional essay can be a good space to discuss your situation. In doing this, it is better not to come off as making excuses. Instead, use this opportunity to play up other highlights of your profile or lessons you have learned from your experience.

For instance, running the family business during an emergency while also attending school is a life experience that instills responsibility and maturity at a young age. Likewise, juggling studies and team practices to represent your school in a particular sport can give context as to why your GPA does not reflect your full potential, while also playing up other dimensions of your profile and helping you stand out.

3) Showcase Your Unique Qualities

Another way to make your MBA application more compelling is to make sure that you present strong, unique qualities or experiences that you can bring to the school. This could be in the form of your diverse background, or through your involvement in an interesting cause. If your GPA is below the norm at the school you are applying to, it is very important to justify why they should accommodate you with a spot. Thus, you need to be able to convince the Admissions Committee that you will be able to truly enrich the experiences of your peers, and of the school community, as a whole.

Identify the specifics of the MBA program you are interested in and show them how you have done well in similar environments. Substantiating this with concrete accomplishments and demonstrated impact will help present how your goals at school, and post-MBA, are both worthwhile and achievable.

Is Your Future Business School a Consulting Feeder Program? [#permalink]
Expert Reply
FROM Veritas Prep Blog: Is Your Future Business School a Consulting Feeder Program?

If you’re interested in consulting post-MBA, understanding how consulting firms view your MBA program is always a good place to start when setting up your recruiting strategy. Consulting companies primarily limit their feeder schools based on cost, as it would be very expensive to comprehensively recruit at every business school.

Another reason feeder schools are limited is experience – consulting firms form relationships with schools and become comfortable with the crop of MBA talent that certain programs provide, giving them no reason to focus on other schools for recruiting. If you are an MBA candidate at such a feeder program, life is good! If you are not, you will have to do a bit more legwork, but you still will have other opportunities for success. Let’s discuss how to distinguish consulting feeders from other MBA programs:

First, you will want to look at the employment report of your program. This report is a treasure trove of information for students when setting up their recruiting strategies. Within this report, you’ll want to review the overall numbers of students going into consulting – this is a good measure of how robust the consulting ecosystem at your school is. The higher the numbers, the more clearly the program is positioned as a feeder.

Next, look at which companies are recruiting at your school. When most candidates think of feeder programs, they think of programs that can get them jobs at MBB (otherwise known as “The Big Three” – the three largest consulting firms in the world). Management consulting is not just limited to McKinsey, Bain, and BCG however, so the depth and the diversity of firms recruiting at a particular school is important, especially for non-feeder programs. However, if you are expressly targeting MBB, it is important to identify whether or not these firms recruit at your program and in what numbers. This information will be useful as you seek to shape your recruiting strategy.

Finally, connect with your career center or consulting club to find out which consulting firms recruit on-campus. This is an important nuance of the consulting recruiting process, as firms that recruit on-campus tend to be more accessible and provide more of an egalitarian opportunity to interview slots for interested students. Firms that consider your program a feeder school will generally be a part of on-campus recruiting, however in some instances, top firms, such as McKinsey, will choose to recruit off-campus to better control the process (even if they consider your program a feeder school). Your program’s career center will have a better idea of where you can find these recruiting opportunities from such companies.

Consulting is one of the most competitive industries to break into, so understanding the relative position of your program in the industry and what this means for your ability to land a post-MBA job offer is key. Utilize this information to best set up an actionable strategy during recruiting season.

Quarter Wit, Quarter Wisdom: Attacking Gerunds on the GMAT! [#permalink]

Expert Reply
FROM Veritas Prep Blog: Quarter Wit, Quarter Wisdom: Attacking Gerunds on the GMAT!

A few weeks back, we talked about participles and how they are used on the GMAT. In that post, we had promised to discuss gerunds more in depth at another time. So today, as promised, we’ll be looking at gerunds. Before we do that, however, let’s examine Verbals.

A Verbal is a verb that acts as a different part of speech – not as a verb.

There are three types of verbals:

  • Infinitives – these take the form of “to + verb”
  • Gerunds – these are the “-ing” form of the verb
  • Participles – these can take the “-ing,” “-ed,” “-en” etc. forms
Gerunds end in “-ing” and act as nouns in the sentence. They can act as a subject, direct object, subject complement or object of a preposition. For example:

Running a marathon is very difficult. – Subject

I love swimming. – Direct object

The activity I enjoy the most is swimming. – Subject complement

She thanked me for helping her. – Object of a preposition

You don’t have to identify the part of speech the gerund represents in a sentence; you just need to identify whether a verb’s “-ing” form is being used as a gerund and evaluate whether it is being used correctly.

A sentence could also use a gerund phrase that begins with a gerund, such as, “Swimming in the morning is exhilarating.”

Let’s take a look at a couple of official questions now:

A recent study has found that within the past few years, many doctors had elected early retirement rather than face the threats of lawsuits and the rising costs of malpractice insurance.

(A) had elected early retirement rather than face

(B) had elected early retirement instead of facing

(C) have elected retiring early instead of facing

(D) have elected to retire early rather than facing

(E) have elected to retire early rather than face

Upon reading the original sentence, we see that there is a gerund phrase here – “rising costs of malpractice insurance” – which is parallel to the noun “threat of lawsuits.”

The two are logically parallel too, since there are two aspects that the doctors do not want to face: rising costs and the threat of lawsuits.

Note, however, that they are not logically parallel to “face.” Hence, the use of the form “facing” would not be correct, since it would put “facing” and “rising” in parallel. So answer choices B, C and D are incorrect.

Actually, “retire” and “face” are logically parallel so they should be grammatically parallel, too. Answer choice E has the two in parallel in infinitive form – to retire and (to is implied here) face are in parallel.

Obviously, there are other decision points to take note of here, mainly the question of “had elected” vs. “have elected.” The use of “had elected” will not be correct here, since we are not discussing two actions in the past occurring at different times. Therefore, the correct answer is E.

Take a look at one more:

In virtually all types of tissue in every animal species dioxin induces the production of enzymes that are the organism’s trying to metabolize, or render harmless, the chemical that is irritating it.

(A) trying to metabolize, or render harmless, the chemical that is irritating it

(B) trying that it metabolize, or render harmless, the chemical irritant

(C) attempt to try to metabolize, or render harmless, such a chemical irritant

(D) attempt to try and metabolize, or render harmless, the chemical irritating it

(E) attempt to metabolize, or render harmless, the chemical irritant

Notice the use of the gerund “trying” in answer choice A. “Organism’s” is in possessive form and acts as an adjective for the noun verbal “trying.” Usually, with possessives, a gerund does not work. We need to use a noun only. With this in mind, answer choices A and B will not work.

The other three options replace “trying” with “attempt” and hence correct this error, however options C and D use the redundant “attempt to try.” The use of “attempt” means “try,” so there is no need to use both. Option E corrects this problem, so it is our correct answer.

Unlike participles, which can be a bit confusing, gerunds are relatively easy to understand and use. Feeling more confident about them now?

Don’t Worry About Your Freshman Roommate! [#permalink]
Expert Reply
FROM Veritas Prep Blog: Don’t Worry About Your Freshman Roommate!

Before my first year of college, one of the biggest things I worried about was the prospect of not liking my freshman roommate. After having my own room (and a decently sized one at that) for all 18 years of my life, the prospect of spending two full semesters in a small dorm with someone I had never met was a scary one.

What if I don’t like him? What if his side of the room is a mess? What if he goes to bed at 4AM and blasts music every night? How is this nondescript roommate questionnaire going to pair me with someone I’m actually compatible with? What if he doesn’t like me? In my mind, the negative possibilities were endless.

In one sense, these fears are reasonable. Since you don’t have many (or any) friends at your new school before the year starts, it makes sense to want to have a perfect relationship with your roommate. Couple that desire with the seemingly random roommate pairing process at many schools, and it’s easy to get anxious.

However, in my experience these fears are oftentimes unfounded. Here are a few reasons why:

You Don’t Have to Be BFFs 

While it may not seem so beforehand, making friends in college is not too hard. That said, it’s not imperative that you and your roommate are best friends for life. Being friends with your roommate certainly doesn’t hurt, but if you aren’t super close, you’ll still be able to easily develop a solid friend group. Plus, sometimes it’s good to look outside your dorm for friendship, since it forces you to expand your horizons and get out to meet people!

Closeness Breeds Compatibility 

Even if there are certain factors that may seem to hinder your compatibility with your roommate, the fact of the matter is that most people are perfectly capable of living with each other. Barring extreme circumstances, most people can get along when they have to.

Additionally, the more you spend time living with your roommate, the more you two can figure out how to room together effectively. As long as you’re nice about it, making small requests like turning the music down or cleaning up the room a bit are likely to help out your situation without harming the room dynamic. Good communication is key – when communication lines are healthy and open, little annoyances can easily be prevented from turning into bigger problems.

(Yes) New Friends 

One overlooked thing about having a roommate is that even if you two aren’t very close, you’ll still get introduced to his or her friends. For me – someone who was friendly with, but not best friends with, my roommate – it was fun getting to know my roommate’s friends and hang out with them in our room. It’s easy to get caught up just in your own friend group, so spending time with my roommate’s friends was a nice change of pace. The ironic thing is that even though I didn’t end up being great friends with my roommate (something I had worried about), I ended up making more friends because of him!

Overall, going into college can be a nerve-wracking time for a lot of people. However, worrying about your freshman roommate is an unnecessary expenditure of worry. Hey, you’ll both be mature, responsible, college-ready adults, and even if you seem different, I’m confident you’ll be able to make it work.

2 Ways to Prepare for Your Campus Visit [#permalink]

FROM Veritas Prep Blog: 2 Ways to Prepare for Your Campus Visit

While time consuming (and often expensive), visiting business schools is a key component of your application process. While you have the opportunity to learn about the campus environment, culture, and student body, the admissions committee has the opportunity to learn about you.

So, where do you begin?

1) Do Your Research

First, do your research. Your business school visit begins long before you actually step foot onto a campus. You will need to narrow down your MBA search so you know which schools you most want to visit. During your initial research, determine what factors are important to you in a business school community. Does the school foster a collaborative environment, or is it more competitive? Does it have a larger or a smaller class size? Do most students commute to campus or do they live within walking distance?

Some of these factors may be more important to you than others. If you’ve always lived in an urban environment, do you want to continue that lifestyle and look into NYU Stern or UCLA Anderson, or are you interested in living in a rural community like at Dartmouth’s Tuck School of Business? If you are going to business school with a partner, you might want to consider the percentage of partnered students in your target programs as well.

Determine which environment you will thrive in. The environment makes up the campus culture, which is an important thing to understand about your target programs before you visit.

2) Start Networking

Once you’ve determined a handful of schools that you want to visit, start networking (if you haven’t already)! Part of your initial research process might involve networking with alumni and admissions officers, but if it doesn’t, now is your chance to get to know some of the people involved with your target programs.

There are several MBA admissions events throughout the world all year long. You can meet with admissions representatives from top programs at events like The MBA Tour and the QS World MBA Tour. At these events, you’ll have the opportunity to get to know admissions representatives, alumni, or both! Talk about your goals and why you are interested in their program. They’ll be able to talk about program specifics that will help with your post-MBA goals, or put you in touch with people who know more.

You can also start to reach out to the leaders of the clubs you are interested in joining once you get to campus. These conversations will help guide your application essays and give you a stronger sense of the school before you hit submit. If you can showcase your understanding of and fit with the program, it makes your applications even stronger!

As you can see, campus visits take a lot of time, so start early. A great place to start your initial search is with the free Veritas Prep Essential Guide to Top Business Schools. With this tool, you’ll learn about schools’ class sizes, average GMAT scores, percentage of partnered students, and so much more. The networks that you start to build with this information will come in handy when you begin visiting campuses. Check out our next post to learn more!

Early Thoughts on Ross’ 2016-2017 Application Essay Questions [#permalink]

FROM Veritas Prep Blog: Early Thoughts on Ross’ 2016-2017 Application Essay Questions

Application season at the University of Michigan’s Ross School of Business is officially underway with the release of the school’s 2016-2017 essay questions. Let’s discuss from a high level some early thoughts on how best to approach these essay prompts.

The essays this year are fairly similar to last year’s prompts, however with a few tweaks:

Essay 1:

What are you most proud of outside of your professional life? How does it shape who you are today? (400 words)

This is a traditional “accomplishments” essay, and Ross has tweaked it this year to really have applicants focus on accomplishments outside of the professional arena. Coming from a very culture-focused campus, this nuance should come as no surprise. Ross has always had a very active student community, so highlighting an example that shows your prior engagement – preferably in a leadership capacity – will show your fit with the program.

Dig deep to identify the topic you are going to discuss; these types of open-ended questions really give applicants the chance to differentiate themselves from other candidates. Make sure, however, you are direct in your approach to answering this question, as Ross’ Admissions Committee has emphasized in the past the importance of answering their question as directly as possible.

Also, keep in mind that you will have time to talk about your professional career and even highlight some of your past accomplishments through the second essay, so keep this first essay tightly focused on your life outside of your professional career (unless your professional career was somehow shaped by this accomplishment).

Finally, don’t assume that if your accomplishment does not involve saving a beached whale or climbing Mt. Everest that your response will not be well-received. What makes your response to this question relevant is the impact this accomplishment had on YOU.

Essay 2:

What is your desired career path and why? (250 words)

This is a typical “career goals” essay and should come as no surprise to any candidate applying to business school. In fact, your answer to this question should be what initially drove your interest in pursuing an MBA in the first place, so Ross will be expecting a fairly polished essay here.

What will separate you from the competition as a breakthrough candidate will be how personalized your essay reads.  Like many other MBA programs, Ross wants students who are truly passionate about their school and who want to be there. With this in mind, they will be looking for you to combine your well-thought-out career goals with details on how you plan to utilize their unique program to reach these goals.

In addition, if relevant, try to connect your goals to an underlying passion you have for the role or industry you are interested in. This will highlight other underlying elements of your personal story and make your goals more tangible to the Admissions Committee.

Hopefully these thoughts on the new batch of essays from Ross will help you get started with your own essays.

SAT Tip of the Week: Calculator Use on the New SAT [#permalink]
Expert Reply
FROM Veritas Prep Blog: SAT Tip of the Week: Calculator Use on the New SAT

At Veritas Prep, our instructors are asked a variety of questions about the new SAT. Some students want to know about the difficulty of the test, while others wonder about the types of questions that will be in each section. One of the most common questions we get is, “What calculators are allowed on the SAT?” Students know that they’ll encounter 58 questions on the Math Section of the new SAT and want be prepared for all of them.

Learn the answer to the above question and find out whether students really need to bring a calculator on test day:

Can You Use a Calculator on the SAT?

Yes, students can use one of the acceptable calculators for some SAT math questions. Students must, however, keep in mind that there are portions of the math section where they are allowed to use a calculator as well as portions where they are not allowed to use one. In addition, a student isn’t required to use a calculator on any part of the test – it’s up to the individual as to whether they need a calculator to answer the questions.

What Calculators Are Allowed on the SAT?

There are certain types of calculators allowed on SAT math questions. Students should be familiar with the guidelines for approved calculators if they plan to take one along on test day. Though calculators are allowed on some SAT math questions, they can sometimes be a hindrance when solving certain types of problems. For example, if a student uses a calculator to answer a question for reassurance rather than trusting their knowledge, they may lose valuable test time. Some questions can be answered more quickly without the help of a calculator. Part of the challenge of the math section on the new SAT is deciding whether or not to use a calculator on any given question.

Types of Calculators to Leave at Home

Some students get really excited when they hear that they will be able to use a calculator on some math problems of the new SAT. Unfortunately, in their excitement, they may forget that they can only bring SAT-approved calculators with them. For instance, it’s likely that a student has a basic calculator on their smartphone, but these devices aren’t allowed into the testing room, so students who show up on test day expecting to use the calculator on their smartphone for the exam will be disappointed.

There are also other devices that are not on the list of SAT-acceptable calculators. A student should not bring a calculator that needs to be plugged into a wall socket, a calculator with a paper tape in it, or one that makes noises when its buttons are pushed. All of these would interfere with the concentration of others in the testing room, so they will not be allowed in. In addition, students should never bring a new calculator that they’re unfamiliar with – students should be concentrating on submitting their best performance on the test, not trying to figure out how to perform functions on a new calculator.

Do Students Need a Calculator to Succeed on the SAT?

It’s up to each individual, though it is recommended that students taking the new SAT bring along an appropriate calculator just in case. But for some students – especially students who rarely use a calculator in their math courses, regardless of what type of math they’re working on – a calculator can get in the way of their thinking. If a student feels at ease answering questions without a calculator, then they should go with what is comfortable.

At Veritas Prep, our knowledgeable instructors teach tips and strategies that can guide students to success. We can advise students on when to incorporate a calculator into their work and when to put their calculator aside. Along with expert instruction, our professional instructors provide students with the encouragement and support they need to feel at ease on the Math Section as well as every other section of the new SAT. Contact Veritas Prep and give us the opportunity to study with you for the new SAT!

FROM Veritas Prep Blog: How to Approach Difficult GMAT Problems

My students have a hard time understanding what makes a difficult GMAT question difficult. They assume that the tougher questions are either testing something they don’t know, or that these problems involve a dizzying level of complexity that requires an algebraic proficiency that’s simply beyond them.

One of my main goals in teaching a class is to persuade everyone that this is not, in fact, how hard questions work on this test. Hard questions don’t ask you do to something you don’t know how to do. Rather, they’re cleverly designed to provoke an anxiety response that makes it difficult to realize that you do know exactly how to solve the problem.

Take this official question, for example:

Let a, b, c and d be nonzero real numbers. If the quadratic equation ax(cx + d) = -b(cx +d) is solved for x, which of the following is a possible ratio of the 2 solutions?

A) –ab/cd

B) –ac/bd

C) –ad/bc

D) ab/cd

E) ad/bc

Most students see this and panic. Often, they’ll start by multiplying out the left side of the equation, see that the expression is horrible (acx^2 + adx), and take this as evidence that this question is beyond their skill level. And, of course, the question was designed to elicit precisely this response. So when I do this problem in class, I always start by telling my students, much to their surprise, that every one of them already knows how to do this. They’ve just succumbed to the question writer’s attempt to convince them otherwise.

So let’s start simple. I’ll write the following on the board: xy = 0. Then I’ll ask what we know about x or y. And my students shrug and say x or y (or both) is equal to 0. They’ll also wonder what on earth such a simple identity has to do with the algebraic mess of the question they’d been struggling with.

I’ll then write this: zx + zy = 0. Again, I’ll ask what we know about the variables. Most will quickly see that we can factor out a “z” and get z(x+y) = 0. And again, applying the same logic, we see that one of the two components of the product must equal zero – either z = 0 or x + y = 0.

Next, I’ll ask if they would approach the problem any differently if I’d given them zx = -zy – they wouldn’t.

Now it clicks. We can take our initial equation in the aforementioned problem: ax(cx +d) = -b(cx+d), and see that we have a ‘cx + d’ on both sides of the equation, just as we’d had a “z” on both sides of the previous example. If I’m able to get everything on one side of the equation, I can factor out the common term.

Now ax(cx +d) = -b(cx+d) becomes ax(cx +d) + b(cx+d) = 0.

Just as we factored out a “z” in the previous example, we can factor out “cx + d” in this one.

Now we have (cx + d)(ax + b) = 0.

Again, if we multiply two expressions to get a product of zero, we know that at least one of those expressions must equal 0. Either cx + d = 0 or ax + b = 0.

If cx + d = 0, then x = -d/c.

If ax + b = 0, then x = -b/a.

Therefore, our two possible solutions for x are –d/c and –b/a. So, the ratio of the two would simply be (-d/c)/(-b/a). Recall that dividing by a fraction is the equivalent of multiplying by the reciprocal, so we’re ultimately solving for (-d/c)(-a/b). Multiplying two negatives gives us a positive, and we end up with da/cb, which is equivalent to answer choice E.

Takeaway: Anytime you see something on the GMAT that you think you don’t know how to do, remind yourself that the question was designed to create this false impression. You know how to do it – don’t hesitate to dive in and search for how to apply this knowledge.

The Most Overlooked Question You Should Be Asking During Your College [#permalink]

FROM Veritas Prep Blog: The Most Overlooked Question You Should Be Asking During Your College Search Process

Colleges, like all other organizations, love to market themselves positively. Their brochures are bright and shiny, filled with impressive statistics, pictures of happy students, and never-ending lists of reasons why they are great. Talk to students, too, and they’re likely to gush about how much they love their schools and how happy they are to be there.

For the most part, these things are true – many colleges have lots of great things about them, and many students are really happy where they are going to school. But for someone doing the college search process and trying to determine which school is the best fit for him or her, this uniform positivity can be a bit unhelpful.

As any rational person will say, no place is perfect, and hence no college is perfect. Every school has at least a few minor issues, and in my opinion, knowing what the negative aspects of a school are is almost as important as knowing what the positive aspects of a school are. This way, a student can make a decision on which school to attend based on a comprehensive understanding of the school, not just a one-sided view of it.

So, one really important question to ask students and staff when considering a school is, “What are some things you don’t like about this school?” Or, in other words, W”hat would you change about your school if you could?”

This might not be the question that you want to ask, or even one that you feel comfortable asking, but it is of utmost importance. You will spend 4 years at the college of your choice, and that time will be a rollercoaster ride of ups and downs. The best way to make sure you’ll be prepared to handle those “downs” is if you have an idea beforehand of what kinds of “downs” they might be.

For example, a school might seem great to you on its website, yet still have a student body culture you don’t like or a greatly underfunded department you thought you wanted to major in. Maybe the walks between classes are really long, or the food options on campus are boring. Maybe the student body differs too greatly from you politically, or the professors care more about research than teaching.

Information like this is hard to find out on your own; finding it requires talking to people who actually live at the school and are willing to offer their honest perspective. Admitting that a school has flaws doesn’t mean you shouldn’t attend the school – it just means that you should choose a school with negative aspects that you are comfortable with and prepared to manage. Whether the issues are big or small, you’ll be a more informed college search-er if you take the time to figure out both the positive and negative parts of a school.

Do you still need to help with your college applications? We can help! Visit our College Admissions website and fill out our FREE Profile Evaluation for personalized feedback on your unique background! And as always, be sure to follow us on Facebook, YouTube, Google+, and Twitter!

GMAT Tip of the Week: How to Avoid GMAT (and Pokemon Go) Traps [#permalink]

FROM Veritas Prep Blog: GMAT Tip of the Week: How to Avoid GMAT (and Pokemon Go) Traps

In seemingly the most important development in world history since humans learned to create fire, Pokemon Go has arrived and is taking the world by storm. Rivaling Twitter and Facebook for mobile phone attention and battling the omnipresent selfie as a means of death-by-mobile-phone, Pokemon Go is everywhere you want to be…and often in places you don’t.

And that is why Pokemon Go is responsible for an ever-important GMAT lesson.

Perhaps most newsworthy about Pokemon Go these days is the dangerous and improper places that it has led its avid users. On the improper side,  such solemn and dignified places as the national Holocaust Museum and Arlington National Cemetery have had to actively prohibit gamersfrom descending upon mourners/commemorators while playing the game. And as for danger, there have been several instances of thieves luring gamers into traps and therefore robbing them of valuable (if you’re playing the game, you definitely have a smartphone) items.

And the GMAT can and will do the same thing.

How?

If you’re reading this on our GMAT blog, you’ve undoubtedly already learned that, on Data Sufficiency problems, you cannot assume that a variable is positive, or that it is an integer. But think about what makes Pokemon Go users so vulnerable to being lured into a robbery or to losing track of basic human decency. They’re so invested in the game that they lose track of the situations they’re being lured into.

Similarly, the most dangerous GMAT traps are those for which you should absolutely know better, but the testmaker has gotten your mind so invested in another “game” that you lose track of something basic. Consider the example:

If y is an odd integer and the product of x and y equals 222, what is the value of x?

(1) x is a prime number

(2) y is a 3 digit number

Statement 1 is clearly sufficient. Since y is odd, and an integer, and the product of integers x and y is an even integer, that means that x must be even. And since x also has to be prime (which is how you know it’s an integer, too), the only even prime is 2, making x = 2.

From there your mind is fixated on the game. You can quickly see that in that case y = 111 and x = 2. Which you then have to forget about as you attack Statement 2. But here’s the reason that less than 25% of users in the Veritas Prep Question Bank get this right, while nearly half incorrectly choose D. Statement 1 has gotten your mind fixated on the even/odd/prime game, meaning that you may only be thinking about integers (and positive integers at that) at this point.

That y is a 3-digit number DOES NOT mean that it has to be 111. It could be -111 (making x = -2) or 333 (making x = 2/3). So only Statement 1 alone is sufficient, but the larger lesson is more important. Just like Pokemon Go has the potential to pollute your mind and have you see the real world through its “enhanced reality” lens, so does a statement that satisfies your intellect (“Ah, 2 is the only even prime number!”) give you just enough tunnel vision that you make poor decisions and fall for traps.

The secret here is that almost no one scoring above a 500 carries over all of Statement 1 (“Oh, well I already know that x = 2!”) – a total rookie mistake. It’s that Statement 1 got you fixated on definitions of types of integers (prime, even, odd) and therefore got your mind looking through the “enhanced reality” of integers-only.

The lesson? Much like Pokemon Go, the GMAT has tools to get you so invested in a particular facet of a game that you lose your universal awareness of your surroundings. Know that going in – that you have to consciously step back from that enhanced reality you’ve gained after Statement 1 and look at the whole picture. So take a lesson from Pokemon Go and know when to stop and step back.

Quarter Wit Quarter Wisdom: What is Your Favorite Number? [#permalink]

FROM Veritas Prep Blog: Quarter Wit Quarter Wisdom: What is Your Favorite Number?

Fans of The Big Bang Theory will remember Sheldon Cooper’s quote from an old episode on his favorite number:

“The best number is 73. Why? 73 is the 21st prime number. Its mirror, 37, is the 12th and its mirror, 21, is the product of multiplying 7 and 3… and in binary 73 is a palindrome, 1001001, which backwards is 1001001.”

Though Sheldon’s logic is infallible, my favorite number is 1001 because it has a special role in standardized tests.

1001 is 1 more than 1000 and hence, is sometimes split as (1000 + 1). It sometimes appears in the a^2 – b^2 format such as 1001^2 – 1, and its factors are 7, 11 and 13 (not the factors we usually work with).

Due to its unusual factors and its convenient location (right next to 1000), it could be a part of some tough-looking GMAT questions and should be remembered as a “special” number. Let’s look at a question to understand how to work with this  number.

Which of the following is a factor of 1001^(32) – 1 ?

(A) 768

(B) 819

(C) 826

(D) 858

(E) 924

Note that 1001 is raised to the power 32. This is not an exponent we can easily handle. If  we try to use a binomial here and split 1001 into (1000 + 1), all we will achieve is that upon expanding the given expression, 1 will be cancelled out by -1 and all other terms will have 1000 in common. None of the answer choices are factors of 1000, however, so we must look for some other factor of 1001^(32) – 1.

Without a calculator, it is not possible for us to find the factors of 1001^(32) – 1, but we do know the prime factors of 1001 and hence, the prime factors of 1001^32. We may not be able to say which numbers are factors of 1001^(32) – 1, but we will be able to say which numbers are certainly not factors of this!

Let me explain:

1001 = 7 * 11 * 13 (Try dividing 1001 by 7 and you’ll get 143. 143 is divisible by 11, giving you 13.)

1001^32 = 7^32 * 11^32 * 13^32

Now, what can we say about the prime factors of 1001^(32) – 1? Whatever they are, they are certainly not 7, 11 or 13 – two consecutive integers cannot have any common prime factor (discussed here and continued here).

Now look at the answer choices and try dividing each by 7:

(A) 768 – Not divisible by 7

(B) 819 – Divisible by 7

(C) 826 – Divisible by 7

(D) 858 – Not divisible by 7

(E) 924 – Divisible by 7

Options B, C and E are eliminated. They certainly cannot be factors of 1001^(32) – 1 since they have 7 as a prime factor, and we know 1001^(32) – 1 cannot have 7 as a prime factor.

Now try dividing the remaining options by 11:

(A) 768 – Not divisible by 11

(D) 858 – Divisible by 11

D can also be eliminated now because it has 11 as a factor. By process of elimination, the answer is A; it must be a factor of 1001^(32) – 1.

I hope you see how easily we used the factors of 1001 to help us solve this difficult-looking question. And yes, another attractive feature of 1001 – it is a palindrome in the decimal representation itself!

How to Use Units Digits to Avoid Doing Painful Calculations on the GMA [#permalink]

FROM Veritas Prep Blog: How to Use Units Digits to Avoid Doing Painful Calculations on the GMAT

During the first session of each new class I teach, we do a quick primer on the utility of units digits. Imagine I want to solve 130,467 * 367,569. Without a calculator, we are surely entering a world of hurt. But we can see almost instantaneously what the units digit of this product would be.

The units digit of 130,467 * 367,569 would be the same as the units digit of 7*9, as only the units digits of the larger numbers are relevant in such a calculation. 7*9 = 63, so the units digit of 130,467 * 367,569 is 3. This is one of those concepts that is so simple and elegant that it seems too good to be true.

And yet, this simple, elegant rule comes into play on the GMAT with surprising frequency.

Take this question for example:

If n is a positive integer, how many of the ten digits from 0 through 9 could be the units digit of n^3?

A) three

B) four

C) six

D) nine

E) ten

Surely, you think, the solution to this question can’t be as simple as cubing the easiest possible numbers to see how many different units digits result. And yet that’s exactly what we’d do here.

1^3 = 1

2^3 = 8

3^3 = 27 à units 7

4^3 = 64 à units 4

5^3 = ends in 5 (Fun fact: 5 raised to any positive integer will end in 5.)

6^3 = ends in 6 (Fun fact: 6 raised to any positive integer will end in 6.)

7^3 = ends in 3 (Well 7*7 = 49. 49*7 isn’t that hard to calculate, but only the units digit matters, and 9*7 is 63, so 7^3 will end in 3.)

8^3 = ends in 2 (Well, 8*8 = 64, and 4*8 = 32, so 8^3 will end in 2.)

9^3 = ends in 9 (9*9 = 81 and 1 * 9 = 9, so 9^3 will end in 9.)

10^3 = ends in 0

Amazingly, when I cube all the integers from 1 to 10 inclusive, I get 10 different units digits. Pretty neat. The answer is E.

Of course, this question specifically invoked the term “units digit.” What are the odds of that happening? Maybe not terribly high, but any time there’s a painful calculation, you’d want to consider thinking about the units digits.

Take this question, for example:

A certain stock exchange designates each stock with a one, two or three letter code, where each letter is selected from the 26 letters of the alphabet. If the letters may be replaced and if the same letters used in a different order constitute a different code, how many different stocks is it possible to uniquely designate with these codes?

A) 2,951

B) 8,125

C) 15,600

D) 16,302

E) 18,278

Conceptually, this one doesn’t seem that bad.

If I wanted to make a one-letter code, there’d be 26 ways I could do so.

If I wanted to make a two-letter code, there’d be 26*26 or 26^2 ways I could do so.

If I wanted to make a three-letter code, there’d be 26*26*26, or 26^3 ways I could so.

So the total number of codes I could make, given the conditions of the problem, would be 26 + 26^2 + 26^3. Hopefully, at this point, you notice two things. First, this arithmetic will be deeply unpleasant to do.  Second, all of the answer choices have different units digits!

Now remember that 6 raised to any positive integer will always end in 6. So the units digit of 26 is 6, and the units digit of 26^2 is 6 and the units digit of 26^3 is also 6. Therefore, the units digit of 26 + 26^2 + 26^3 will be the same as the units digit of 6 + 6 + 6. Because 6 + 6 + 6 = 18, our answer will end in an 8. The only possibility here is E. Pretty nifty.

Takeaway: Painful arithmetic can always be avoided on the GMAT. When calculating large numbers, note that we can quickly find the units digit with minimal effort. If all the answer choices have different units digits, the question writer is blatantly telegraphing how to approach this problem.
