So you have a few more days to commit to your New Year’s Resolution, and if you’re like most people you have something like 35 days until you break it. Resolutions don’t often stick, but if your New Year’s Resolution is to apply to business school in 2014, and if as part of that resolution you’re planning to get a high GMAT score, you’re in luck:

When preparing for the GMAT, you may notice that studying for one subject makes you better in other disciplines as well. For example, practicing your algebra tends to make you better at algebra, arithmetic tends to make you faster at picking numbers and the entire quant section helps you significantly in integrated reasoning. This is due to the fact that many subjects overlap and have common elements. More formally, you can say that the GMAT is an exam with a lot of synergy.
In the first part of this article we discussed recent research indicating that exercise is the only way to create new brain cells, protect existing brain cells, and form new neural networks. If that list is not enough, aerobic exercise is also an important component of healthy emotions and possibly even control of test anxiety.
We know the basics of decimals and rational numbers.
- Decimals can be rational or irrational.
- Decimals which terminate and those which are non-terminating but repeating are rational. They can be written in the form a/b.
- Decimals which are non-terminating and non-repeating are irrational such as √2, √3 etc.
One of the things that makes Reading Comprehension difficult is the inclusion of so many words that you either don’t know or don’t spend much time thinking about. Triglyceride, germination, privatization, immunological.
But by the same token, certain words – those that you should think about regularly if you don’t already – can make your job exponentially easier. Consider, for example, these sentence fragments from the beginnings of official GMAT passages:
The most common complaint I hear from students about Reading Comprehension is that the text is mind-numbingly boring. This is due to two common factors. First, the texts are frequently mind-numbingly boring! Second, even if they’re somewhat interesting, the fact that you’ve been staring at a computer screen for about three straight hours (not counting the two eight-minute breaks) means you’re likely not completely focused on the task at hand. In fact, many a student has confided in me that by this part of the test they were already dreaming of lunch at McDonalds (okay this may have just been my personal experience).
This is hard to confess publicly but I must because it is a prime example of how GMAT takes advantage of our weaknesses – A couple of days back, I answered a 650 level question of weighted averages incorrectly. Those of you who have been following my blog would understand that it was an unpleasant surprise – to say the least. I know my weighted averages quite well, thank you! For this comedown, I blame the treachery of GMAT because it knows how to get you when you become too complacent. The takeaway here is – no matter how easy and conventional the question seems, you MUST read it carefully.
The axiom has been tweaked and twisted so often that perhaps no one knows the exact term, but we all know the definition.
The definition of insanity is…
The definition of stupidity is…
(WAIT! Google confirms that it’s insanity, but you’ve probably heard it as any number of terms)
This past Friday, key people from the Graduate Management Admission Council (GMAC) and representatives from various test prep companies came together in Los Angeles for the biannual GMAT Summit. The summit, which first ran in 2005, was created to improve transparency in the GMAT and to break down some of the most persistent myths around the exam. GMAC deserves a lot of credit for having a rather open-minded approach about test prep companies (We’re not steroids dealers, after all!), and the GMAT Summit is a great example of this approach.
One of the most common misconceptions on the GMAT is that you have to solve every question in about 2 minutes. This of course stems from the fact that you have 75 minutes to answer 37 quantitative questions (or ~2.03 minutes per question) and 75 minutes to answer 41 verbal questions (or ~1.83 minutes per question). Both figures can be approximated to roughly two minutes per question on average; however, this does not mean that every question will take you 2 minutes to solve.
You may not know it yet, but there are simple things that you can do right now, that will help you to not only score higher on the GMAT but also succeed in business school and beyond. Getting exercise should be the first change on your list!
The New York Times has written extensively recently on the connection between exercise and brain health. It turns out that iPads, video games, smart phones, computers, even crossword puzzles…do not make lasting changes in your brain structure; only exercise does. So if you want to be better at answering the questions on “Jeopardy!” you should turn off the TV and go for a brisk walk.
While eagerly awaiting the kick off of season 3 of BBC’s Sherlock, let’s put our time to good use. Though we have already spent a lot of it speculating over what really happened to Sherlock (HOW did he come back?!), perhaps we can take a leaf out of his book and learn to notice little things in whatever is leftover. There is a good reason to do that – there are little clues in some questions that the test maker unwittingly leaves to bring clarity to the question. If we understand those clues, a seemingly mysterious problem could be easily unraveled. Let us show you with an example.
While it’s certainly not the score you care about most, the Analytical Writing Assessment can bring with it some stress and even despair. Why? For one, it comes first on the test, and for two it’s the only section that isn’t multiple choice. The answer isn’t already in front of you, but rather you have to create it yourself. And like this blog post (author’s note – I’m attending a conference with the folks from the Graduate Management Admissions Council and have a dinner in an hour with some of our partners in the industry before the conference, so I have 30 minutes to write something intelligible here), the AWA can lead directly to that panic you’ve likely felt on blue book exams and the night before book reports: writer’s block.
On the GMAT, there is often a fine line between a statement possibly being true and a statement always being true. Inference questions ask about which statement must be true, and often provide many statements that each seem to be correct. However, must be true is a high standard to achieve, and many statements fall short of this benchmark despite being perfectly reasonable assumptions on their own.
When faced with an unusual quadratic equation, some people waste a lot of time while trying to ‘split the middle term’. The common refrain is ‘I am just not good at it.’ Actually it has little to do with intuition and a lot to do with understanding how numbers work. If I am looking at a quadratic equation and am unable to find the required factors, I will go back to check my quadratic to see if it is correct rather than try to use the esoteric quadratic formula.
Do some of your best ideas come while you’re driving, running, taking a shower or just about to fall asleep? Have you ever spent what felt like an eternity reading a solution over and over again to no avail, only to revisit that problem a few days later and know how to do it almost so intuitively that just feels easy?
Here at Veritas Prep, we have a long list of reasons to be thankful this year! From our students, to our incredible teachers and admissions consultants, it’s truly been an amazing year.

Whether you are trying to hit Round 2 business school deadlines or are planning on taking the SAT next year, make sure to take a look at our discounts and register before these prices are no longer available.
In Data Sufficiency, the GMAT is asking you to determine how much information is required to make a decision. If the information provided leads you a definite yes, then you have sufficient data to take decisive action. Similarly, if there is enough information to lead to a definite no, then you can also take decisive action. The only time trouble arises is when the information could lead to a yes or to a no; this situation leaves you in a position where you may have to guess (I’ll take Door #1, Bob).
The holiday season is upon us in much of the world, and in the U.S. there is a special holiday this year called “Thanksgivikkah!” This is a combination of the words “Thanksgiving” and “Hanukkah” (The first full day of Hanukkah happens to be on November 28th this year – the same day as Thanksgiving in the U.S. This has never happened before and will not happen again in any of our lifetimes).
Coming back to Integrated Reasoning question types, let’s discuss a cumulative graph today. They are usually a little trickier than your usual line/pie/bar graphs since you have to focus on not the data points but ‘the change’ from one data point to another. Every subsequent data point will be either above or at the same level as the previous data point.
Today marks the 50th anniversary of the assassination of US President John F. Kennedy, and amidst all of the memorial articles and TV specials and conspiracy theories, you’ll undoubtedly see that email forward that details the eerie similarities between the two presidents assassinated almost 100 years apart, Kennedy and Abraham Lincoln:
When evaluating critical reasoning questions, you often notice multiple answer choices that all seem plausible. The GMAT testmakers are experts at creating answer choices that are plausible and could potentially be correct, given slightly different circumstances. When evaluating strengthen or weaken questions, it is best to predict an answer from the stimulus before looking at the answer choices. That way you won’t be swayed by logical but out of scope questions (plus it’s a surprise!)
The GMAT is not merely a test for graduate school. Several very valuable qualities of the mind, useful in the course of human life, are to be acquired or strengthened by it, so as to become habits, ready on all occasions. Let’s examine a few of these qualities:
1. Decisiveness, which looks at the information and question, and considers the best course of action; for it occurs to the test taker, ‘how can I break this down into something I can figure out quickly? What is the situation and question really getting at? Can I ballpark or use the answer choices to narrow it down? How much time is worth spending to get this?’
Last week, we introduced the idea of “mirroring” in data sufficiency, and this week we’ll continue on that subject and look at different types of mirrors. “Mirroring” is my way of speaking about a technique called “manipulate algebraically” where the test taker attempts to manipulate either the statement or the question itself (or both) in order to get those statements to match each other exactly.
I know I promised that I will bring you some tricky Integrated Reasoning questions this week, but I am really irked by the ‘which’ vs ‘that’ debate and would like to put it to rest once and for all. Hence, in this post I would like to talk about restrictive and non-restrictive clauses, about ‘which’ and ‘that’, about when to use a comma and some other such things.
If you’ve been following the strangest story to hit the NFL since Manti Te’o did, you’ve probably noticed that Richie Incognito is nowhere near incognito. There’s nothing subtle or understated about the guy. He’s Rob Ford in a different jersey. But there’s something about that name…
One of the most important concepts on the GMAT quant section is the notion of factors. Because there is no calculator on the exam, the multiplications and divisions tend to heed integer numbers. Dividing 100 by 2 might be trivial, but dividing 1100 by 22 might hinge on your recognition of the common factor of 11 to avoid tedious and time-consuming calculations.
In the Veritas Prep Data Sufficiency book, we have a section called the “Data Sufficiency Toolkit.” This toolkit contains a technique called “Manipulate Algebraically.” This technique involves “manipulating” either the statement or the question stem (or both) so that they exactly match each other.
On a timed test like the GMAT, test-takers often fall victim to a simple fact about the way the English language works: we read from left to right.
Why is that? We’re often in such a hurry to make a decision on each answer choice that we make our decisions within the first 5-10 words of a choice without being patient and hearing the whole thing out. A savvy question creator – and rest assured that the GMAT is written by several of those – will use this against you, embedding something early in an answer choice and baiting you into a bad decision.
The official website of the GMAT states, “You can take the GMAT once every 31 calendar days and no more than five times in a 12-month period.” This is good news. The GMAT isn’t a one-shot deal. It does mean, though, that you should select and, more importantly, prepare for your test date carefully.
In many ways, critical reasoning questions best exemplify what the GMAT is all about. The exam is primarily an exercise in applying logic to various different situations. In the quant section, you must either find the correct answer or determine whether you have sufficient information to make a decision. On the verbal section, you must find the answer choice that logically completes the information given in the question stem. Even on the AWA and the IR, logic is again paramount to knowing how to proceed and getting a good score.
Critical Reasoning is more than just one of the three verbal sections on the GMAT. It’s a way of thinking that applies to every GMAT subject area. In fact, it’s more still. It’s a skill that has wide application outside the GMAT.
The classic example of a lack of critical reasoning is the groupthink that led to the mortgage crisis, which eventually caused the global financial crisis. Very few people questioned the assumption that house prices would continue to rise. As long as prices rose, homeowners would be able to refinance their mortgages when, for example, low introductory interest rates increased or when balloon payments came due. And the system would keep chugging along. But it didn’t…
Now that we have seen some basic Integrated Reasoning question types, we will look at some tricky questions but not this week. This week, we would like to discuss a Critical Reasoning question. This question is simple and straight forward but still many people falter in it. The reasons for this are not hard to find. Let’s analyze this question in detail.
Some stories are best told in the first person, so forgive me for the break from journalistic standards. As a longtime GMAT instructor – 10th anniversary coming up next month actually – I most empathize with my students when I’m preparing for any big event of my own, usually running and triathlon races. The months of grinding preparation, the sleepless night before the event, that helpless “if I’m not ready by now I guess I’ll never be ready, so here goes nothing” last week before the big day… I get to feel what my students feel leading up to their GMAT, and symbiotically I can both learn more about that experience and benefit from the advice I’ve always given about the GMAT.
Percentages represent one of the most underestimated question types on the GMAT quant section. Absolute numbers are helpful to give concrete information (I spent 70$ on the latest Grand Theft Auto game), but percentages give a better indication of relative amounts of time (I spend 68% of my free time playing GTA V). Based on the first, you may find that I overpaid for the video game, but based on the second statistic, I probably got a very good return on my investment.
As you are probably well aware, success on the quantitative section of the GMAT requires not only computational ability, but also test taking acumen. For example, the fact that you are capable of determining a particular quantity from the information given in a problem does not mean that it is necessarily in your best interest to do so. At this point, you may assume that what follows is a discussion of data sufficiency (DS) strategy.
Let’s continue our series and look at another Integrated Reasoning question type today – two part analysis. As complicated as it sounds, it’s actually the simplest of the IR question types in my opinion. The reason for this is that it tests no new skills; it checks your ability to handle the same old PS and CR questions.
