On the GMAT quantitative section, you have just over 2 minutes on average to answer each question in front of you. Sometimes, those two minutes go by in a flash and you feel like the question should take at least 4 minutes in order to even make a reasonable guess. Other times, you think you can solve the question in a matter of seconds, and wonder why anyone would take a full 2 minutes on a question that you can eyeball without putting pen to paper (or marker to dry erase board). Because the 2 minute benchmark is an average, not a maximum, figuring out how much time to spend on each question is a crucial part of doing well on this test.

When reading through Reading Comprehension texts, there are a few important concepts to keep in mind in order to be able to swiftly answer the upcoming questions. Every passage will have explicit information regarding the subject matter at hand, but some information will come from the author’s attitude and writing style. One of the most important things to do while reading a Reading Comprehension passage (other than staying awake) is determine the author’s tone.
I have to admit that probability is confusing. The problem is not so much that students find it hard to understand as that teachers find it hard to explain. There are subtle points in a probability question that make all the difference in the world and it takes a ton of ingenuity to explain them in a manner that others understand. You either get the point right away, or you don’t.
If you’ve had grand plans all summer of taking some time to focus on the GMAT so you can apply to business school, but you’ve gotten sidetracked with barbecues and weekends at the beach and other outdoor activities, you’re not alone. Summertime was made for procrastination and recreation. But as sure as every Target and Wal-Mart ad out there is advertising “Back to School” specials on notebooks and backpacks, whether you’re entering kindergarten or hoping to enter Harvard Business School soon, it’s back-to-school time, time to get on a more regimented study routine. If, like most students, you’ve let your study habits wane over the endless summer, here are five ways to get back in gear to hit those October Round 1 deadlines or the January Round 2 deadlines with a positive GMAT experience this fall:
Ten months ago we introduced the Veritas Prep GMAT Question Bank, giving every GMAT student around the world completely free access to hundreds of realistic GMAT questions of all types. Today, we celebrate an incredible milestone: more than one million GMAT questions served!
We introduced the most common sense way of approaching a simple work rate problem last week in Part I. No setup was necessary. There was zero possibility for a calculation error, or a misconception.
The past perfect tense in a GMAT Sentence Correction question can subtly change the meaning of a sentence, making an answer choice incorrect, even if the verb agrees with its subject in number. The past perfect tense is often used to describe an action that was completed prior to another past action:
By now, you know that we like to discuss visual approaches to problems. A visual tool that we have used before for solving inequality and modulus questions is the number line. The number line is also useful in helping us solve many number properties questions.
A few things to keep in mind when dealing with number line:
The Veritas Prep Question Bank offers unique insights in to the habits of GMAT test-takers; while students from around the world answer free GMAT practice questions, the Question Bank tracks patterns in the answers that the world selects, and in this series we’ll highlight valuable lessons that you can learn from the statistical analysis of how people choose their answers.
Just as all roads lead to Rome (well, all roads in Europe anyways), there are many ways to solve math questions on the GMAT. Any question can conceivably be solved in a variety of ways, but they must always be logical. No method is inherently superior to any other, so often it’s a question of which method will solve this particular problem in the most efficient way possible.
Combined work rate problems give many a headache at their mere mention. After all, you have to think in terms of that fourth dimension, “time” (cue the Twilight Zone theme). This alone puts it up there with Einsteinian Relativity in terms of difficulty. There are always three moving parts – time, work, and speed – and sometimes three or more machines or people working together.
A few months back, one of our posts talked about knowing which numbers to plug-in in case you want to use the number–plugging method. To be more exact, we discussed that you need to find the transition points i.e. the points where the two sides of the inequality become equal. The transition points tend to reverse the relation between the two sides. For a detailed discussion of this concept, revisit this post.
Statistics-based GMAT questions can be tricky, particularly for those who haven’t been formally trained in stats or for those whose knowledge of statistics is more incomplete than they realize. One concept for which many students have blind spots is that of the median, so let’s take a moment to identify and explain a few of these common knowledge gaps.
Many GMAT students have likened themselves to Sherlock Holmes at one point or another while studying for this test. It is a natural comparison: you are a detective looking for clues in order to reach a conclusion that must be true. Unfortunately there’s no Dr. Watson to help guide your efforts, but you can inspire yourself from the super sleuth in your quest to solve the nefarious puzzles of Professor G. MoriArTy.
Welcome to the third and final installment of GMAT’s secrets revealed! We now know 2 things the GMAT testmakers don’t want you to know – one, they can do most quant problems entirely in their heads, and two, verbal complexity is intended to clarify, not confuse, a given situation. These insights are a critical part of the recognition that the GMAT is not actually as difficult as it is intimidating. It has a lot of tough-looking math and long, dense passages, but that’s mainly on the surface – deep down, unlocking GMAT reasoning is feasible for anyone.
We began last week with a quant trick demonstrating the 1st Thing GMAT Testmakers Don’t Want You to Know: they can do quant problems entirely in their heads! This was no doubt a carefully guarded secret, but now that it’s out there, it should take the intimidation factor of those difficult-looking quant problems down a notch or two.
Most people who plan to take GMAT seriously take a few prep tests, practice tests or mock tests, whatever you may like to call them. Usually, the tests are taken to gauge one’s current level i.e. to get an approximate idea of what one would score if one were to take GMAT that day. Of course, they have other uses too – practice in timed environment, build stamina, identify strengths and weaknesses etc. Usually, these tests are fairly accurate (with an error of up to 40-50 points in the total score). A recent phenomena has been much lower score (especially verbal) compared to the prep test scores (not among Veritas Prep students though – I will explain the reason for this soon).
One of the most fascinating parts of being a GMAT instructor is getting to watch successful adults relive the math they did as kids. In many cases, an instructor can actually see that concept or point in time when the student stopped trying to really understand the math and just started relying on that combination of memorization and partial credit to get their Bs in math and search for a career path that would include no more of it. How many students decided at some point in junior high or high school that they just weren’t a “math person”?
As a GMAT instructor, I frequently find myself perusing the GMAT Official Guide, dare I say, “for fun”. The OG is a terrific indication of the types of questions you can expect to see on the GMAT, and the solution is usually a great method to get to the right answer. However, sometimes I find myself surprised at the official answer because I would solve the question in a completely different way and get to the answer in significantly less time than the OG method.
Studying for the GMAT in just one month is nobody’s idea of a party, but sometimes it can’t be avoided. If you’re locked in to your test date and need to make the best of a bad situation, wipe that perspiration off your brow and take a deep breath: it is possible to significantly improve your score in one month! In fact, depending on your latent test-taking, grammar, algebra, number properties, time management, and general cool-as-a-cucumber skills, you probably already have a LOT of the needed requirements found in a 700+ scoring GMAT test-taker. Here’s some quick tips to conquer content, strategy, and pacing in only 4 weeks.
As I discussed in my last entry on The Art of War and success on the GMAT, the makers of the GMAT have only a few ways to attack you in battle. They also have a few things that keep a figurative arm tied behind their back. These limitations are what you can, and should, exploit to your advantage. However, it may still not be clear who exactly you’re dealing with. And as you remember, knowing thy enemy (and thyself) is key to a great score.
Let’s look at a question today which encompasses most of what we have discussed in this topic. This will be the last post on this topic for a while now. We assume that after going through these posts thoroughly, if you come across any question on ‘this inscribed in that’, you should be able to handle it. Just a reminder, keep in mind the symmetry of the figures you are handling.
“A rose by any other name would smell as sweet.” – Juliet / William Shakespeare
Carlos Danger is Anthony Weiner. And a creep by any other name would be just as creepy. This week the New York mayoral candidate, notorious for tweeting his last name all across the internet, put his campaign into his fake last name by doing the same thing under an alias. And in doing so, he taught many of you who aspire to live under his intended jurisdiction – as students at NYU-Stern or Columbia, or as bankers or marketers or hip-hop moguls after graduation – a valuable lesson about the GMAT:
Many concepts covered on the GMAT come up in every day conversation. One of the common mistakes frequently tested on the GMAT that people make mistakes with in colloquial speech is that lack of agreement between a subject and verb when the verb is placed before the subject (There’s a lot of reasons this happens…) People make this mistake regularly and no one really seems to notice it, but the GMAT thoroughly tests this type of mistake, so you likely will have had sufficient exposure to this scenario by test day.
At $250, the GMAT is not a cheap test, and when you consider that many students take it two or three times, the fees really add up. If you’re concerned about the cost and believe you can demonstrate extreme financial need, it’s possible to take the GMAT for free (or at least discounted)!
How can you do this? In 2001 GMAC created a voucher program to assist students who might not otherwise be able to take the exam. GMAC’s CEO David A. Wilson was quoted in Businessweek online that year describing the initial implementation of the voucher program:
Last week we looked at questions on polygons inscribed in a circle. This week, let’s look at questions on circles inscribed in regular polygons. As noted earlier, it’s important to keep in mind that regular polygons are symmetrical figures. You need very little information to solve for anything in a symmetrical figure.
A common question we get from students who have just completed our free GMAT practice goes something like this: “I just got a score of X, but I see that I got Y questions right and Z questions wrong… How can my score be so low/high?” Embedded in this question is a bit of a lack of understanding of how a computer-adaptive test (CAT) works. Let’s dig in…
With a fairly consistent test format for more than fifty years, the Graduate Management Admissions Council has revamped the test with a couple of assessment changes in the past few years. Most recently, the Integrated Reasoning Section, a 30-minute portion of the GMAT made up of 12 questions, was designed to measure one’s ability to discern patterns and combine verbal and quantitative reasoning so solve problems. While the admissions committees at top schools seem to continue focusing on the traditional verbal and quantitative score combination (out of a possible 800), we will likely see an emphasis shift towards these new sections in the future (which also include a 30-minute writing analysis of a topic), since the skills they measure are critical to today’s business leaders.
When answering data sufficiency questions on the GMAT, the key is to successfully determine when you have sufficient information to make a decision with 100% certainty. I often equate data sufficiency with determining whether the competition is stealing from you. If you’re sure they are not, then everything is fine and you are competing in a fair and balanced environment. Similarly, if you have definitive proof that they are hijacking your million dollar idea (possibly for pet rocks or the duck commander), then you can pursue legal action to remedy the situation.
Each year, eager b-school hopefuls line up to take the GMAT, and each year many end up with a score below what they had been getting on their practice exams. What went wrong? Why the discrepancy? The answer is never easy to ascertain, but there are several questions you can ask yourself to try and figure out what happened. One of the most important ones is actually rather simple: did you practice for the test environment as well as for the questions themselves?
“You can learn a lot more from a few seconds of pain than from a few hours of glory.”
We all want to breeze through our GMAT homework getting every question right in under two minutes, but absolutely no one does that. And if you’re in a GMAT class, do you really want to get every answer right the first time? Sure, that might mean that “you’re great”, but in reality what it probably means is that the class is going through problems that are too easy. The beauty of mistakes – and the reason that Veritas Prep classes emphasize “Learning by Doing” with challenge-level problems throughout – is that they’re the best learning opportunities out there. Every time you make a mistake, you’re adding another lesson to the pile and finding a new hole to plug. Every mistake you make in practice is a chance to make sure you learn to avoid that mistake for when it really matters.
There is a lot of value in keeping things simple. Simplicity is a beautiful thing, especially when combined with functionality. Think of the designs Apple comes up with (or at least did when Steve Jobs ran the show): products were simple, sleek, stylish, and routinely worked flawlessly. The appeal and popularity of these machines is steeped in how effortlessly they perform their functions, combining reliable functionality and timeless elegance.
We often get asked by clients how many times they should take the GMAT before they move on to other components of the application. Of course this largely depends on your score, but if you find yourself disappointed with your initial test results, you will generally want to try again.
Broadly speaking, schools don’t really care how many times you take the test, and will only consider your highest score. Know that they won’t combine separate components into one score, but will consider your best overall score from one sitting as your “application score.” Having said that, it is also generally agreed upon that schools don’t want to see applicants taking the exam a dozen times. This can communicate negative qualities to the admission’s committee such as poor time management skills, slow learner syndrome, or good old fashioned poor judgment or misalignment of priorities.
Today we will work with circles inscribed in regular polygons.
We begin by considering an equilateral triangle whose each side is of length ‘a’. Recall that every triangle has an incircle i.e. a circle can be inscribed in every triangle. The diagram given below shows the circle of radius ‘r’ inscribed in an equilateral triangle.
Ah, summertime. Perhaps you’re spending this first-weekend-of-July at the Jersey Shore, or perhaps you have plans to watch baseball. Either way, there’s a good chance you’ll run into an MVP comparison, and if you do you’re helping your GMAT verbal score more than you’ll ever know. Because the key to Sentence Correction success is the MVP comparison.
Two words that often get confused in the English language are effective and efficient. Many people use these words as if they are synonyms, when, in fact, they are two distinct notions that only sound like homonyms. In fact, the words effective and efficient complement each other perfectly. How does this affect the GMAT? While both words are usually used as compliments, their effect on the exam is very noticeable (see what I did there?)
Last week, I introduced the idea of timing on the GMAT. Today, we will look at the technique which helped me a lot in reducing my stress and improving my time management. Have a look, take away the main methodology and please feel free to adjust certain parts of it to suit your own purposes.
Hemingway wrote his prose in a manner which has come to be known as the “Iceberg Theory.” Influenced by his journalistic career, Hemingway believed that by omitting superfluous and extraneous matter, writing becomes more interesting. The minimalistic style of a Hemingway piece is a lesson all GMAT students can apply to their AWA writing: take out the fluff! Argument essays that receive scores of 6 typically are “fluff-free” zones – the paragraphs are organized and to the point, and they say what they mean to say.
GMAT students can now benefit from a new blog series featuring video tips from Veritas Prep’s own Director of Academic Programs, Brian Galvin. Last week, Brian helped us spot pronoun errors in Sentence Correction by ‘minding the gap.’ This week, we’ll learn about the adaptability and scoring of the GMAT.
