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.
The GMAT is of course one of the most important components of the application process, so there is little else more devastating than not doing well on it. Often, applicants find their actual performance is below their practice exams, leaving them not only bewildered and shocked, but also desperate with anxiety. Schools know how tough the test is, and expect to see applicants who have taken it more than once, but a common question always seems to be: how many times is too many? It might help to first discuss how schools look at the test overall.
Read the following sentences:
- About 70 percent of the tomatoes grown in the United States come from seeds that have been engineered in a laboratory, their DNA modified with genetic material not naturally found in tomato species.
- The defense lawyer and witnesses portrayed the accused as a victim of circumstance, his life uprooted by the media pressure to punish someone in the case.
- Researchers in Germany have unearthed 400,000-year-old wooden spears from what appears to be an ancient lakeshore hunting ground, stunning evidence that human ancestors systematically hunted big game much earlier than believed.
Which grammatical construct is represented by the underlined portions of these sentences?
The GMAT is an intimidating test. Here are 3 strategies to help you succeed on test day:
1) Check your work and be thorough.
Because of the Item Response Theory powered adaptive scoring engine, the GMAT comes with a substantial “penalty” for missing questions below your ability level. As the test attempts to home in on your ability level, it knows that approximately 20% of the time when you completely guess on problems that are beyond your ability, you’ll guess correctly. So the system is designed to protect against “false positives.” So even if you don’t get that hard problem right “accidentally,” but rather by investing extra time at the expense of other problems, the algorithm will continue to hit you with hard enough problems to undo the benefit of your getting that one outlier problem right. The same isn’t as true for “false negatives’ – problems below your ability level that you get wrong. There, that’s all on you – and getting easy problems wrong hurts you more than getting hard problems right helps you. So while your energy and attention may well naturally go toward the problems you find the most challenging, you simply cannot afford more than 1-2 silly mistakes on test day. Those wrong answers give the computer substantial data that your ability is lower than you’d like it to be, and the system responds by showing you even easier questions to determine just “how low can you go?”.
There are few things more alluring than shortcuts. Oftentimes we’re aware of how much work, effort or time is required to accomplish a task, but we naturally gravitate towards something that can accomplish that task faster. From buying readymade rice to taking elevators to go up two floors, we’re drawn to things that make our lives even a modicum simpler (including dictionaries). This is why so many people are disappointed when they first learn that the calculator is not allowed on the GMAT.
This week we will look at the question on races that we gave you last week.
Question 3: A and B run a race of 2000 m. First, A gives B a head start of 200 m and beats him by 30 seconds. Next, A gives B a head start of 3 mins and is beaten by 1000 m. Find the time in minutes in which A and B can run the race separately?
“I have not failed. I’ve just found 10,000 ways that won’t work.” -Thomas Edison, speaking about mistakes.
If you study for the GMAT for any appreciable amount of time (and you should) you’ll make mistakes. And that’s a good thing. People love to track their study progress with all kinds of metrics: percent correct, time per question, hours spent, problems completed – but in the end the only numbers that matter are the numbers on your official score report. So whether you were 10 for 10 on your homework or 0 for 20, whether you took less than 2 minutes per problem or spent almost an hour trying to figure it out, the key “metric” to your study sessions should be “what did I learn from this?”. And you can learn a lot from the mistakes you made, whether they’re silly (“I forgot to convert hours to minutes”) or confusing (“why does it matter that health care quality improved in the last three decades?”). You just need to know which questions to ask about the questions you missed. And there are four questions you should ask yourself any time you miss a problem:
There are many famous expressions in the English language. Many of them are clever turns of phrase that refer to commonplace ideas and concepts in everyday life. You obviously don’t need to memorize these for the GMAT (A house divided against itself is not an integer), however some expressions can be easily applied to various GMAT problems. One common expression is that you’re comparing apples and oranges. This expression typically means that you are attempting to compare two elements that are not analogous and therefore incomparable. This idiom can be particularly apt in sentence correction problems.
The following article comes from Eliza Chute, a motivated GMAT self-studier who scored an impressive 770 on the GMAT. Eliza utilized numerous resources to help her prepare for the GMAT, including Veritas Prep’s GMAT Question Bank and GMAT Practice Test. Here, Eliza describes her experience using both resources and makes strategic recommendations for how to get the most out of each resource to help you with your GMAT preparation.
Steven Wright is a comedian known for his deadpan delivery, and, it turns out, has a lot to say – in his dry, paraprosdokian way – about the logic of the GMAT. Never ones to let insight go to waste, we can (somewhat, perhaps) better understand the GMAT with his Wit and Wisdom:
Suddenly the chances of scoring in a top percentile don’t seem so bad.
Panic starts to creep in.
“How could this have happened? I was doing so well!”, you think. “What do I do now?”
A bad practice test can happen to anyone. In isolation, it’s certainly not the end of the world, but you should use the result to diagnose what went wrong and how to fix it moving forward. There are several potential causes worth considering. Let’s look at a few:
Let’s discuss races today. It is a very simple concept but questions on it tend to be tricky. But if you understand how to handle them, most questions can be done easily.
A few points to remember in races:
1. Make a diagram. Draw a straight line to show the track and assume all racers are at start at 12:00. Then according to headstart, place the participants.
GMAT Tip of the Week: Come On,Commas! 3 Reasons You Should Look Forward To Commas On Sentence Correction
Admit it – perhaps your favorite thing about the social media revolution is that you’re (or is it “your”?) almost done having to think about punctuation ever again. Hashtags don’t allow for punctuation, and with only 140 characters to express your point of view or challenge three friends to dump water on their heads, who can afford to waste a character on a comma or semicolon?
A common mantra heard when studying for the GMAT is that you have to be fast when answering questions. This is absolutely true, as the exam is testing not only your reasoning skills but also your time management skills. This does not, however, necessarily mean that you must solve every question quickly. Indeed, there may be times where you feel fairly confident in the answer choice you’ve selected, but you don’t feel 100% certain (maybe a strong 60%). In these situations, it’s perfectly acceptable to double check your answer manually.
For those considering higher education this week, Robin Williams’ memory looms large. The lessons he taught in Dead Poets’ Society and Good Will Hunting have made their way around the internet more quickly and in more contexts than even Williams’ genie character from Aladdin could throw out references.
The GMAT is known to be a demanding exam. Most students recognize that a lot of preparation is required in order to get the best score possible. Most students undertaking the GMAT are also used to studying for tests and have worked out their own strategies and their own methods of preparation. Indeed, people overwhelmingly study the GMAT in an orderly and structured way. This is a positive thing, but it can have its drawbacks.
As pointed out by a reader, we need to complete the discussion on a question discussed in our previous ‘Advanced Number Properties’ posts so let’s do that today. Note that the discussion that follows doesn’t fall in the purview of GMAT and you needn’t know it. You will be able to solve any question without taking this post into account but that has never stopped us from letting loose our curiosity so here goes…
After you read this post about what to look for before you begin reading a Sentence Correction problem, you’ll be an SC expert since this strategy will tell you when to shift your focus from whatever it’s on to timeline and tense. Ready to get started?
On the GMAT quantitative section, the exam is testing your logic and analytical skills using mathematics as a medium. The topics used include geometry, algebra and arithmetic, all concepts that have been covered in high school curriculums around the world. However, the emphasis is really on the logic more than the math. In short, the question is simply asking you to solve a given problem by any means at your disposal. As such, many questions can be solved without doing any math whatsoever.
Let’s get back to strategies that will help us reach the coveted 51 in Quant. First, take a look at Part I and Part II of this blog series. Since the Quant section is not a Math test, you need conceptual understanding and then some ingenuity for the hard questions (since they look unique). Today we look at a Quant problem which is very easy if the method “strikes”. Else, it can be a little daunting. What we will do is look at a “brute force” method for times when the textbook method is not easily identifiable.
As our attention spans get shorter, the GMAT’s verbal section gets harder. Admit it – at some point in the verbal section of your latest practice test, and maybe earlier in that section than you’d like to admit, you just got bored, or at least lost in all the reading.
In today’s world of instant gratification and ubiquitous mobile phone usage, we are becoming used to things going fast. Multitasking has become the new norm, and it seems like no one takes the time to finish anything before jumping off to the next task. While this hectic pace may allow more tasks to be accomplished (although not necessarily well), it also makes it harder for any one task to be attentively completed. In short, it’s becoming harder to finish any one thought.
If you want to bring your “A Game” on the Quant section you need to be very comfortable with Algebra.
There is one mathematical discipline that dominates the Quant section of the GMAT: Algebra. The majority of the math questions that you will see on test day involve algebra.
Many questions involve pure algebra, such as expressions and equations involving variables, roots, and exponents. Another large group of questions is word problems, most of which are best addressed using algebraic equations. Geometry is another significant subject on the GMAT; and geometry is simply a delivery mechanism for algebra. Even things like ratios can often best be addressed by using equations with “x” as the multiplier.
We will continue our Quant 48 to 51 journey in the coming weeks but today, we need to discuss an important distinction between assumptions and inferences. Most of you will be able to explain the difference between an assumption and an inference but some questions will still surprise you. After all, both assumptions and inferences deal with the same elements in the argument. The way they are worded makes all the difference.
In life, it’s important to have a hobby or pastime that you find interesting. Sometimes, when the daily grind of work, school, family, social responsibilities, (updating Facebook) and preparing for the GMAT just seems like too much to handle, it’s good to take a step back. Diving into a hobby helps take your mind off things by pausing everything else and concentrating on something personal and somewhat intimate to you. One of my favorite diversions is watching movies and immersing myself in the fictional world created on screen. Surprisingly, this same distraction can be applicable to GMAT studying as well.
I recently received the following question from a student. “I often get into trouble with ambiguous pronouns. If it is not clear what “they” or “it” refers to I eliminate the answer choice. I like to do this because it seems easy, but I keep getting burned using this technique. So my question is, if it is not clear what a pronoun refers to is that answer choice wrong?”
If you’re taking the GMAT with the intent of applying to a top-tier business school, there’s a relatively fair chance that you’ll end up having/wanting to retake the GMAT. Which may sound horrible, but it’s true – in fact, several top schools note that their average students take the test more than twice, so if you see a frustrating score pop up during your first, second, or even third attempt don’t let yourself get too down. Rest assured that:
One common complaint that people have when finishing the GMAT is that they are mentally exhausted. Indeed the exam is a marathon that tests your overall endurance, but also your time management skills. You have about two minutes per question in the math section, and slightly less than that on the verbal part. Since timing is such an integral part of the exam, it’s important not to lose too much time on any specific question type on the exam. It’s perfectly natural to be more at ease with certain question types and thus process them faster than others, but you don’t want to have entire categories of questions you’re trying to avoid (or at least, not too many of them).
This month, the Graduate Management Admissions Council began offering new versions of the popular Official Guide for GMAT Review series, now labeling by year (OG 2015) as opposed to edition (the last was the 13th). For the nuts and bolts we’ll let you read the official press release or visit the official website, but here’s what you should know about the new resources:
People often ask – how do we go from 48 to 51 in Quant? This question is very hard to answer since we don’t have a step by step plan – do theory from here – do questions from there – take a test from here – read posts from there etc. Today and in the next few weeks, we will discuss how to go from 48 to 51 in Quant.
GMAT Tip of the Week: LeBron James Says Don't Be Cavalier About Your Initial Data Sufficiency Decision
It’s all anyone can talk about today – LeBron James has decided to reverse “The Decision” and return home to play for Cleveland. In doing so he forced many people to change their minds.
Let’s take a look at some of those people:
-LeBron himself, who once decided to leave and now comes home as the prodigal son
-Cavaliers owner Dan Gilbert, who once wrote a scathing letter about James the week he left the Cavs for South Beach
-Cavaliers fans, who once burned LeBron’s jersey and rallied against him
-Dwayne Wade, who just last week opted out of a $40 million contract to restructure his deal to create space to attract more players to his and LeBron’s Heat team
One common complaint I hear from GMAT students is: “I can get the right answer but it takes me too much time.” Many people preparing for the GMAT feel this way at one point or another during their preparation. While this complaint has some merit, it can usually be paraphrased as “I’m approaching the problem with little to no strategy.” Relying on brute force to get the right answer is rarely the best approach. The old adage states that a million monkeys writing on a million typewriters will eventually produce the greatest novel of all time (It was the best of times, it was the blurst of times…).
In today’s post, we will give you a question with two solutions and two different answers. You have to find out the correct answer and explain why the other is wrong. But before we do that, let’s give you some background.
Given an n sided polygon, how many diagonals will it have?
An n sided polygon has n vertices. If you join every distinct pair of vertices you will get nC2 lines. These nC2 lines account for the n sides of the polygon as well as for the diagonals.
