One topic that always makes me think on the GMAT is geometry. It’s not that geometry is particularly hard, or even particularly easy, but rather that it’s particularly irrelevant! Having done an MBA in the past few years, I can virtually guarantee you that you will never have to calculate the area of a rhombus or the volume of a cone during your graduate studies. It’s possible that you have to calculate various geometric shapes in your career after graduating (say you run an ice cream shop!), but during your education the entire discipline seems somewhat superfluous.

You must have come across questions which you thought tested one concept but later found out could be easily dealt with using another concept. Often, crafty little mixture problems belong to this category. For example:
Mark is playing poker at a casino. Mark starts playing with 140 chips, 20% of which are $100 chips and 80% of which are $20 chips. For his first bet, Mark places chips, 10% of which are $100 chips, in the center of the table. If 70% of Mark’s remaining chips are $20 chips, how much money did Mark bet?
Today is December 5, or in date form it’s 12/5. And if you hope to score 700+ on the GMAT, you should see those two numbers, 5 and 12, and immediately also think “13”!
There are certain combinations of numbers that just have to be top of mind when you take the GMAT. The quantitative section goes quickly for almost everyone, and so if you know the following combinations you can save extremely valuable time.
The holiday season is upon us in North America, as many families unite for Thanksgiving, some decadent shopping, and the imminent Christmas season. While Thanksgiving and Christmas are independently two of the biggest holidays of the year, the fact that they always come together and are so habitually linked makes me think of the GMAT (yes a lot of things make me think of the GMAT, it’s what I do). Just as the thought of Christmas makes a lot of people think of Black Friday deals and line ups at their local stores, some elements on the GMAT are as inextricably linked together.
There was an article in the Wall Street Journal recently about how the GMAT is slowly but authoritatively being dominated by international applicants. Not only is there an increasing number of international hopefuls taking the test, they are also performing remarkably better than US test-takers. The numbers are staggering. Test takers from America, in fact, now only make up about 36% of all GMAT hopefuls, which is down considerably over the past several years. As a comparison, Asia-Pacific students now make up 44% of total test takers.
Matt Hamilton is a graduate of the United States Military Academy at West Point where he was commissioned as and engineer officer in the US Army. He has served in Afghanistan and is currently preparing to transition to a full-time MBA program. He just completed the GMAT and with the help of Veritas Prep, he raised his score from a 580 to a 750!
We have discussed weighted averages in detail here but one thing we are yet to talk about is how you decide what the weights will be in weighted average problems. It is not always straight forward to identify the weights. For example, in a question such as this one,
When going through the quantitative section of the GMAT, you will often be confronted by numbers that are, shall we say, unwieldy (some people refer to them as “insane”). It is common on the exam to see numbers like 11!, 15^8, or even 230,050,672. Regardless of the form of the number, the common mistake that many novice test takers make is the same: They try to actually solve the number.
A few weeks back, we wrote a post busting some Sentence Correction myths. Let’s continue from where we left. We discussed how we can have pronouns referring to different antecedents in different clauses of the same sentence. Let’s take another example illustrating that principle. Also, we learn how to use ‘being’ correctly in GMAT.
The following interview comes from Top GMAT Prep Courses. Top GMAT Prep Courses recently had the opportunity to conduct a Q&A session with Chris Kane, one of Veritas Prep’s most seasoned GMAT instructors, to inquire about the GMAT and get his take on 10 great questions that many MBA candidates would like to ask with regards to GMAT prep courses and useful tips on how to be successful at achieving their desired GMAT score.
In life, you are often given binary choices. This is true even if the word binary isn’t something you recognize right away. Binary comes from the Latin “bini”, which means two together, and is used to regroup decisions in which you have exactly two choices. On forms, you might see categories such as “smoker” or “non-smoker”, and you are prompted to answer exactly one of the options. At a restaurant, you might get asked “Soup or salad?” (super salad??), and you are expected to make a decision as to which appetizer you want. Very frequently, these two choices cover the entirety of your options. There is no third option to select.
First, let us give you the link to the last post of this series: Post IV. It contains links to previous parts too.
Today, we bring another tip for you to help get that dream score of 51 – if you must write down the data given, write down all of it! Let us explain.
This week’s video post brings you a tip for taking a closer look at the data in Data Sufficiency. Is what you know about Data Sufficiency statements really sufficient? There are certain points of information that are necessary to know for Data Sufficiency, but knowing those doesn’t mean you have sufficient information to correctly solve the problem.
If you’ve ever built a puzzle, you probably know that you can’t expect to start at a certain point and build the entire puzzle without moving around. You may find two or three pieces that fit together nicely, but then you find three pieces that fit together nicely somewhere else, and then work to connect these disparate sections.
First, we would like to refer you back to a post we put up quite a while ago: The Holistic Approach to Mods
In this post, we discussed how to use graphing techniques to easily solve very high level questions on nested absolute values. We don’t think you will see such high level questions on actual GMAT. The aim of putting up the post was to illustrate the use of graphing technique and how it can be used to solve simple as well as complicated questions with equal ease. It was aimed at encouraging you to equip yourself with more visual approaches.
When dealing with questions that ask us to compartmentalize information, there are two major sorting methods that we can use on the GMAT. The first, and perhaps more familiar concept, is the Venn diagram. This categorization is very useful for situations where information overlaps, as it allows a visual representation of multiple categories at once. However, if the information provided has no possible overlap, such as indicating whether something is made of gold or silver, or if they’re male or female (Bruce Jenner notwithstanding), the preferred method of organization is the matrix box.
A couple of weeks back, we looked at a 750+ level question on mean, median and range concepts of Statistics. This week, we have a 750+ level question on standard deviation concept of Statistics. We do hope you enjoy checking it out.
Before you begin, you might want to review the post that discusses standard deviation: Dealing With Standard Deviation
The GMAT is more than just a math or verbal test – it’s a reasoning test. And so it’s important to think not merely about content, but also about the strategy games that the authors of these questions play with that content. One mantra to keep in mind is “Think Like the Testmaker”, reminding yourself to pay just as much attention to why the wrong answer you chose was tempting (how did the author trick you) as to why the correct answer was right.
Last year, I wrote an article for this blog discussing the pros and cons (and pros and cons and pros) of cancelling your GMAT score. At the time, you had to sit through an entire 3+ hour exam, go through every question asked and then be offered the possibility of cancelling your score without ever knowing what your grade would have been.
A student recently asked, “How do I learn to focus long enough to make my study sessions worthwhile? While studying for the GMAT I can only study for about an hour at a time.”
My response is, “This is a clearly a problem, not just for study sessions but also for the GMAT itself which requires 4 straight hours of focus.
Today we will bust some SC myths using a question. The following are the myths:
Myth 1: Passive voice is always wrong.
Active voice is preferred over passive voice but that doesn’t make passive voice wrong.
Myth 2: The same pronoun cannot refer to two different antecedents in a sentence.
The most common question type that people tend to waste time on is Reading Comprehension. More than any other question type on the GMAT, students report reading and rereading the same sections of a passage, only to find themselves at the bottom of the page having retained no information. There are many reasons for this, from fatigue to mental inertia to daydreaming about the end of this test. However, it’s fairly common to have not internalized all the information in the passage, and still be able to answer the question asked.
I recently had the chance to answer a question about overcoming Test Anxiety on the GMAT. The test-taker wanted to know how to avoid being so anxious on test day and how to stop obsessively thinking about the score before and even during the exam itself.
I wrote, “Your job on test day is to focus on the question in front of you. Not to guess at what your score might be or continually estimate how much time you have left per question.
Today, we have a very interesting statistics question for you. We have already discussed statistics concepts such as mean, median, range etc in our QWQW series. Check them out here if you haven’t already done so:
Totes McGotes. FML. Sorry for partying. I know, right? Of the common phrases that have permeated pop culture and everyday conversation, easily one of the most common is, wait for it…
Wait for it.
And that one phrase can totes make your GMAT score supes high. Like, for real.
One of the most difficult tasks on the GMAT is to properly interpret what the question is really asking. The GMAT is loaded with dense terminology, accurate but irrelevant prose and confusing technical jargon (and that’s just the instruction page!) The verbiage is dense on purpose, with the deciphering of the information part of the skills being tested. And since this task only gets more challenging as you get more tired throughout the exam, it’s important to recognize the vocabulary used on the GMAT. To borrow from geek culture, you need to understand the GMAT 1337 speak.
Today, as promised last week, we will look at a couple of questions involving participle modifiers. We will take one question in which you should use the participle and another in which you should not.
Some sentence structures seemingly stupefy scholarly students. One of the main reasons the GMAT chooses to test logic through sentence correction is that the rules of grammar are much more flexible than most students realize. We (hopefully) remember some of the basic rules of sentences. Sentences should have a subject and a predicate, but you can often shorten sentences in specific contexts. Like this. The rules we’ve learned in high school are relevant, but (to paraphrase Pirates of the Caribbean) they’re more like guidelines.
There is a lot of confusion surrounding the topic of Participles so let’s take a look at it today.
Quite simply, participles are words formed from verbs which can be used as describing words (on the other hand, gerunds are verbs used as nouns, but that is a topic for another day!).
There are two types of participles:
1) What is the VIN number on your car?
2) What is your health insurance policy number?
3) What day does Daylight Savings Time start this coming spring?
If you’re like most people, your answer to all three is “I’d have to look that up.” And if you’re like most successful GMAT test-takers, that should be your answer to most Reading Comprehension questions, too. Particularly for questions like:
Succeeding on the GMAT requires a great many things. Firstly, you must be able to decipher and solve complex logic puzzles in mere minutes. Secondly, you must be able to maintain focus for many consecutive hours. (And thirdly, you must pay to take the exam). The exam can be particularly tricky because the questions asked are rarely straight forward. Indeed, all of these elements are often linked (except potentially the payment) on questions that ask you to decode functions specific to the question at hand.
Starting this Monday, October 6th, you can benefit from various sample GMAT prep classes taught by Veritas Prep’s course creator and Vice President of Academics, Brian Galvin. Over the course of next week, we will be offering an introductory session to the GMAT as well as sample Critical Reasoning and Data Sufficiency classes.
We have read a lot about one way of handling complex questions – simplify them to a question you know how to solve. Here is another way – first do what you do know, and then figure out the rest!
We know that basic concepts are twisted to make advanced questions. Our aim is to break down the question into two parts – ‘the basic concept’ and ‘the complexity’. You can either deal with the complexity first and then glide through the basic concept or you can glide through the basic concept first and then face the complexity. The method you use will depend on the question. If the question seems too complex at the outset, it means you will have to deal with the complexity first. If the question seems familiar but has some extra not-so-familiar elements, it means you should get the familiar out of the way first. Let’s take a question today to see how to do that.
It all looked so obvious: a storybook ending preordained from the beginning, some early success and a bit of good fortune leading to a glorious success story. But wait! Then fate intervened, and the easiest part of all had something different to say. And only then was true glory to be had, a glory much greater than that inevitable win ripped away just moments ago.
There is one feeling that hampers momentum and takes all the wind out of your sails on the GMAT. That feeling is the thrill of quickly eliminating three incorrect answer choices on a question, followed by complete uncertainty between the last two choices. This paralysis is very frustrating, because your progress is halted in dramatic fashion, and you’re left with two options that both seem to make perfect sense as the correct answer.
Most of us know that GMAT is a shrew, (euphemism for a more choice adjective that comes to mind!) and is very hard to tame. It is well established that it is able to give a pretty accurate estimate of aptitude with just a few questions, and that the only way to “deceive” it is by actually improving your aptitude! It has numerous tricks up its sleeves to uncloak a rather basic player.
Ah, autumn. The busiest GMAT season of the year as application deadlines and back-to-school nostalgia fill the air, and that season always coincides with Major League Baseball’s pennant races and playoffs. And whether you’re a baseball fan or not, as an aspiring MBA you’ll find a fair amount of overlap between the two, as both the GMAT (and business) and baseball prominently feature the art of probability.
Questions on the GMAT can be described in many different ways. I’ve heard them described as everything from juvenile to vexing, simple to impossible. One term that appears very infrequently as a characteristic of the questions on the GMAT is the word “clear”. Indeed, some questions are so convoluted that they appear to be written in Latin (or Aramaic if you happen to already speak Latin). This is not a coincidence or an accident; many GMAT questions are specifically designed to be vague.
Today we continue to look at ways to achieve that much desired score of 51 in Quant. Obviously, we don’t need Sheldon Cooper’s smarts to realize that for that revered high score, we must do well on the high level questions but the actual question is – how to do well on the high level questions?
I’ve often contemplated who would excel at the GMAT. After all, the exam is about logic, analytical skills, problem-solving abilities and time management. Surely to shine on the exam a test taker should be smart, methodical, insightful and perceptive (and blindingly handsome). Clearly, some people have done quite well on this exam, but others never got the chance because they never actually took the test. While some have been intimidated by the nature of the test, others simply were born too early to have even heard of this exam.
