A GMAT Formula to Remember: Profit on One, Loss on Another

A GMAT Formula to Remember: Profit on One, Loss on Another

I am no fan of formulas, especially the un-intuitive ones but the one we are going to discuss today has proved quite useful. It is for a concept tested on GMAT Prep so it might be worth your while to remember this little formula.

When two items are sold at the same selling price, one at a profit of x% and the other at a loss of x%, there is an overall loss. The loss% = (x^2/100)%

GMAT Tip of the Week: Change the Way You Think About Change-Related Graphics Interpretation

GMAT Tip of the Week: Change the Way You Think About Change-Related Graphics Interpretation

One of the great benefits of the Veritas Prep Question Bank is that with its 4 million user responses to GMAT practice questions it does an excellent job of highlighting test-taker trends. These statistics can point out trap answers that examinees too readily fall for, conceptual areas that students need to address, and other valuable insights into the way the world takes the GMAT. And this week, one particular trend caught our eye in a major way:

Use This Valuable Method to Determine Scope in Reading Comprehension on the GMAT

On test day, you will see 78 different questions designed to test how you think, how you approach a given problem, and how well you manage your time in a stressful environment. Most of these questions are unknown to you. You’ve probably spent tens of hours poring over hundreds of GMAT problems and trying to dissect questions from every possible vantage point. However, there is one question you are guaranteed to see on test day, and the question is deceptively simple. At one point, in the verbal section, you will simply be asked: “What is the primary purpose of this passage”

What The Big Bang Theory Can Teach You about the GMAT Super Power You Didn't Know You Had

What The Big Bang Theory Can Teach You about the GMAT Super Power You Didn't Know You Had

In this series we return to classic movies (and TV shows!) to learn fundamental strategies for GMAT Success.

My friends from the television show The Big Bang Theory are fond of super heroes. Okay Sheldon and Leonard are not really my friends (unfortunately) but they are certainly fond of super heroes. They love Superman and Batman and the entire Justice League.

Determining the Area of Similar Triangles on the GMAT

Determining the Area of Similar Triangles on the GMAT

Recall the important property that we discussed about the relation between the areas of the two similar triangles last week – if the ratio of their sides is ‘k’, the ratio of their areas will be k^2. As mentioned last week, it’s an important property and helps you easily solve otherwise difficult questions. The question I have in mind today also brings in focus the Pythagorean triplets.

GMAT Tip of the Week: ASAP Test Taking Can Be Rocky (That's Your Freaking Problem)

As Hip Hop Month draws to a close in the GMAT Tip of the Week space, it’s time to pass the torch to the new school; while Eminem, Tupac, the Wu Tang Clan, and other classic acts have taught you some important lessons about the GMAT, it’s time for the young bucks to impart some wisdom. So today we bring you an important message from A$AP Rocky, Drake, and Kendrick Lamar, who will show you one of the most common (f****g) problems that test-takers encounter while taking the GMAT.

Follow This Strategy to Save Time on the GMAT

Follow This Strategy to Save Time on the GMAT

There are certain numbers that will show up on every GMAT. Some of these numbers you need to be able to manipulate, and some others will just lie there like the rocks of Stonehenge: static and immovable. Numbers like π and √2, which can be converted into decimals but generally simply encumber the equation.

The Most Efficient Way to Study Least Common Multiples on the GMAT

The Most Efficient Way to Study Least Common Multiples on the GMAT

I recently had a student write in to ask me, “Can you explain to me the reasoning behind the Least Common Multiple? I understand that you take the prime factors from each number but I have no idea why. I think if I understood why I would be better at this technique.”

Let me see if I can make this concept more approachable for you. Think about calculating the Least Common Multiple as if you were a builder getting ready to build a house. The problem is you do not know which house you are going to build. So when you show up on the job site you need to have all of the materials for each of the possible houses. The “houses” are the numbers and the “materials” that you need are the prime factors.

Looking for Similar Triangles on the GMAT

Looking for Similar Triangles on the GMAT

Our Geometry book discusses the various rules we use to recognize similar triangles such as SSS, AA, SAS and RHS so we are assuming that we needn’t take those up here.

We are also assuming that you are comfortable with the figures that beg you to think about similar triangles such as

GMAT Tip of the Week: The Whole Sentence Mathers

Welcome back to Hip Hop Month in the Tip of the Week space, where today we’ll cover Sentence Correction’s most devious wordplay with the rap god of wordplay himself, Eminem. Fans of Slim Shady and connoisseurs of Sentence Correction alike will note the similarity between the two: sometimes, when you least expect it, a word all the way at the end will tie back so beautifully to one all the way at the beginning that it’s just mindblowing. In Eminem’s case, you have to rewind the track to listen to it again – did he really carry that rhyme all the way back like that?! – but on the GMAT you can’t rewind, so it’s important to heed Marshall’s advice well before you put on those noise-reduction headphones (Beats by Dre?) at the test center and zone into the verbal section:

How Hard is the Verbal Section of the GMAT?

How Hard is the Verbal Section of the GMAT?

Two weeks ago I wrote an article about whether the GMAT was hard. It is a question I get asked regularly from many different students with many different interpretations of what “hard” actually means. On test day, you may get a question that seems impossible to solve, and yet most other students get it right. This means that the question wouldn’t be considered difficult by the GMAT (say a 500 level question), but for you it seemed exceptionally difficult. The notion of difficulty is thus subjective, and while many would argue that the GMAT is hard, I have a much simpler explanation I have been postulating for the past couple of years:

GMAT at the Movies: What Austin Powers Can Teach You about Similar Triangles

In this series we return to classic movies to learn fundamental strategies for GMAT Success.

In the Austin Powers movies the character known as “Dr. Evil” creates an exact version of himself, only smaller, that he calls “Mini-me.” The two characters have identical proportions even though one evil villain is 8 times the size of the other. The hero, Austin Powers, quickly recognizes the similarity, despite the difference in size. This is something that you will need to be able to do on the GMAT!

And as it so happens, arguably the best of those slow jams – Tupac’s “Life Goes On” – is a perfect metaphor for GMAT test-day strategy:

I could have sworn that I had discussed negative remainders on my blog but the other day I was looking for a post discussing it and much as I would try, I could not find one.

The Importance of Timing on the GMAT

The Importance of Timing on the GMAT

One of the main goals of the GMAT is to determine whether or not you can analyze a situation in front of you and determine the information needed to solve the question. In this way, the GMAT is testing the same skills required to solve a business case. The numbers in front of you are not important, but your method of solving the question is. Crunching numbers and measuring hypotenuses are not useful skills in business; you’ll have a calculator (or an abacus) to do that. Understanding how to approach and solve problems is the true skill being tested.

Is This GMAT Question Suspect?

I came across a discussion on one of our questions where the respondents were split over whether it is a strengthen question or weaken! Mind you, both sides had many supporters but the majority was with the incorrect side. You must have read the write up on ‘support’ in your Veritas Prep CR book where we discuss how question stems having the word ‘support’ could indicate either strengthen or inference questions. I realized that we need a write up on the word ‘suspect’ too so here goes.

GMAT Tip of the Week: Learning Math from Mathers

March has traditionally been “Hip Hop Month” in the GMAT Tip of the Week space, so with March only hours away and winter weather gripping the world, let’s round up to springtime and start Hip Hop March a few hours early, this time borrowing a page from USC-Marshall Mathers. There are plenty of GMAT lessons to learn from Eminem. He’s a master, as are the authors of GMAT Critical Reasoning, of “precision in language“. He flips sentence structures around to create more interesting wordplay, a hallmark of Sentence Correction authors. But what can one of the world’s greatest vocal wordsmiths teach you about quant?

Is the GMAT Hard?

As a GMAT instructor, I get asked a lot of questions about the exam. Most of these questions are about what can be done to prepare for the exam and what to concentrate on, but one of the simplest questions I get asked all the time is simply: “Is the GMAT hard?” Sadly, the answer is not very clean cut for a given prospective student, but I’ve spent enough time thinking about this test that I now have a definite answer that I think captures the heart of what is being tested. My answer is simply this:

3 Ways to Increase Your GMAT Score to a 760

3 Ways to Increase Your GMAT Score to a 760

Everyone who takes the GMAT wants to get a good score. The exact definition of “good” varies from student to student and from college recruiter to college recruiter. However no one can argue that scoring in the top 1% of all applicants can be considered anything less than a good score. Getting into your local university’s business program may not require a terrific score, but it can’t hurt to have one.

4 Practical Suggestions to Avoid Multitasking and Raise Your GMAT Score

4 Practical Suggestions to Avoid Multitasking and Raise Your GMAT Score

In the first two parts of this article we learned that multitasking causes a host of problems that can be particularly detrimental to GMAT scores. Research shows that multitasking makes it very difficult for a person to focus, damages the short-term memory, makes it hard to sort the relevant from the irrelevant, and slows down the transition from one task or way of thinking to another.

GMAT Tip of the Week: If You Can't Be With the Sentence You Love, Love the One You're With

Happy Valentine’s Day, a day when we honor the soulmate, that one special someone, the concept of true love and destiny. Valentine’s Day is about finding “the one” and never letting go, and this day itself is about being with that one you love, your one true destiny.

But if you think your destiny includes Harvard, Stanford, or Wharton, your Sentence Correction strategy should be a lot less “Endless Love” and a lot more “Love the One You’re With”. As Crosby, Stills, Nash and Young sing directly about the art of GMAT Sentence Correction:

Forget Your Prior Knowledge When Solving GMAT Critical Reading Questions

The GMAT is an exam that students generally study for over a few months, but it can be argued that students have been preparing for it their entire lives. From mastering addition in elementary school to understanding geometric properties and reading Shakespeare sonnets, your whole life has arguably been a prelude to your success on the GMAT. You might not need everything you’ve ever learnt on this one exam, but you will already have been exposed to everything you need to be successful.

How Multitasking Can Hurt Your GMAT Score: Part II

How Multitasking Can Hurt Your GMAT Score: Part II

If you read part 1 of this article you know that multitasking can result in attention difficulties and problems with productivity. You may not think that all of this talk about decreased productivity and being distracted would apply to the GMAT; after all there is no chance to update your Facebook status and “tweet” during the test right?  So this must have no impact. However, when it does come time to concentrate on just one thing – for example, the GMAT – researchers have found that multitaskers have more trouble tuning out distractions than people who focus on one task at a time.

How to Breakdown Data Sufficiency Sequence Questions on the GMAT

How to Breakdown Data Sufficiency Sequence Questions on the GMAT

Sequence questions come up fairly regularly on the GMAT quantitative section. One of the biggest problems students report on these questions is that they can’t determine what the terms in sequence should actually be. As such, the first important thing to determine is the value of the first few elements of the sequence. Without this information, the question seems much more abstract and difficult to follow.

How Multitasking Can Hurt Your GMAT Score

Do you “multitask”?  Probably you do.  A survey showed that “the top 25 percent of Stanford students use four or more media at one time whenever they’re using any media. So when they’re writing a paper, they’re also Facebooking, listening to music, texting, Twittering, et cetera. And that’s something that just couldn’t happen in previous generations even if we wanted it to.”

Dangling Modifiers on the GMAT

Dangling Modifiers on the GMAT

Properly identifying incorrect modifier constructions, which are common errors in Sentence Correction, is a key component in achieving a high score on the GMAT. Knowing that modifier errors are among the most common errors seen on the GMAT, the astute student carefully studies the rules of correctly using modifiers. These grammatical constructions, among the most difficult to spot at a glance, confuse students and frustrate test takers who haven’t adequately prepared for the exam.
