A student of mine once emailed me after he took the GMAT. Instead of telling me his score, he wrote, “let’s just say that 4 times my score is a multiple of 88, and 5 times my score is a multiple of 35.”

Can you tell what he got? If not…you may need to work on your GMAT translation skills! Read more

If you’ve ever read any of my articles, then you know how much I harp on the idea that the GMAT is primarily a test of your business decision-making, or executive reasoning, skills. Sure, there’s a bunch of facts and rules you need to know, but you don’t need to be a math or grammar superstar in order to get a good score on the GMAT (even though I know it feels that way sometimes).

You do, though, have to be a GMAT master. Business schools want to know that you are going to be a good executive. You can assess a situation rapidly, noticing positive and negative factors that may affect how you want to move forward in that situation. You make appropriate decisions most of the time and you follow through: if you decide that a particular product line needs to be cut, you make that cut. You don’t dribble in another million dollars because you’re reluctant to let go. In short, you can manage your scarce resources (time, money, people) masterfully.

The GMAT is the same game, though your scarce resources on the test are time and mental energy. As such, it is crucial to approach the test as a series of business decisions, not a school test.

How do you take the test with a business mindset? Glad you asked! Read on. Read more

Manhattan Prep GMAT Instructor Jonathan Schneider explains some of the most common mistakes he sees students make when studying for the GMAT.

Be sure to check back every Tuesday for a new video in our GMAT 101 series, detailing the answers to some of the most frequently asked questions about the GMAT.

Recently, we took a look at a story problem dealing with ratios, and I finished up by giving you a second problem to test your skills. How did you do?

If you haven’t already, try the GMATPrep® problem below and then we’ll talk about it. Give yourself about 2 minutes. Go! Read more

Have you ever worked with someone who inevitably managed to come up with things to do that were a complete waste of time? Maybe it was an insecure boss who was never confident about what he was doing, so he went for the “everything and the kitchen sink” approach to generating deliverables in the last few days before the deadline. Or maybe it was a fellow student on a group project, someone so diligent (cough, cough) that she wanted to turn in a 20-page report when the teacher suggested 10 pages (and actually specified a 12-page limit).

You know who I’m talking about, right? We’ve all run across these situations in our academic or working lives. You want to be polite…but you also want to get your work done and not waste time on activities that don’t really help you reach the overall goal.

The GMAT is trying to waste your time

Okay, the test writers are not literally sitting there cackling and saying, “How can we get them to waste their lives?!?” But the overall sentiment still holds because of the way that the GMAT is constructed. You already know the classic “If you get something right, they give you something harder” pattern, right?

Well, at some point, that “something harder” is going to be something that isn’t worth your time. You’re probably not going to get it right no matter what you do. Even if you do, you’re going to use up valuable time that you could be using on other problems.

Most important of all, you’re going to be using up your finite brain energy on something that probably isn’t going to pay off. How many times in your life have you crashed towards the end of a test or a long day at work because your brain just couldn’t keep going any longer? The GMAT is a “where you end is what you get” test: if you crash before the end of the section, your score will suffer greatly.

This is basically no different than that co-worker who’s trying to get you to build a marketing presentation when the client has specifically requested that you analyze the pros and cons of acquiring a competitor. Tomorrow at the client meeting, it won’t matter how good your intentions were. Your client is going to be mad that you wasted time on something that doesn’t actually help them.

You’ve heard a million times that you’re supposed to create Official Guide (OG) problem sets in order to practice for the test. But how do you actually do so in a way that will help you get the most out of your study?

Fear not! This article is coming to your rescue.

Initially, when you’re studying a new topic or problem type, you won’t do sets of problems; instead, you’ll just try one problem at a time. As you gain experience, though, you’re going to want to do 3 problems in a row, or 5, or 10.

Why?

Because the real test will never give you just one problem!

The GMAT will give you many questions in a row and they’ll be all jumbled up—an SC, then a couple of CRs, then back to another SC (that tests different grammar rules than the first one), and so on.

You want to practice two things:

(1) Jumping around among question types and topics

(2) Managing your timing and mental energy among a group of questions

When do I start doing problem sets?

You’re going to use problem sets to test your skills, so you’ve got to develop some of those skills first. If you’re using our Strategy Guides to study, then at the end of one chapter, you’ll do only two or three OG problems to make sure that you understood the material in the chapter.

Later, though, when you finish the Guide, do a set of problems that mix topics (and question types) from that entire book. Make sure you can distinguish between the similar-but-not-quite-the-same topics in that book, and also practice your skills on both problem solving and data sufficiency. As you finish subsequent Guides, your sets can include problems from everything you’ve done so far. Keep mixing it up!

How do I make the sets?

You’ll need to balance three things when you create a problem set:

(1) Number of problems. Initially, start out with about 3 to 5 problems. As you gain experience and add topics, you’ll increase the size of the sets—we’ll talk more about this a little later.

(2) Type of problem and content.
(a) For quant, always do a mix of Problem Solving (PS) and Data Sufficiency (DS). For verbal, mix at least two of the three types; you can include all three types in larger sets.
(b) Do not do a set of 3 or more questions all from the same chapter or content area—for example, don’t do 3 exponents questions in a row. You know exactly what you’re about to get and the real test will never be this nice to you.

(3) Difficulty level.
(a) Include a mix of easier, medium, and harder questions in your set. For all types except Reading Comprehension, the OG places problems in roughly increasing order of difficulty. On average, aroblem 3 is easier than a problem 50, which is easier than a problem 102. (This does not mean that problem 5 is necessarily harder than problem 3. In general, higher question numbers represent harder questions, but the increase is not linear from problem to problem.)
(b) Note: your personal strengths and weaknesses will affect how you perceive the problems—you might think a lower-numbered problem is hard or a higher-numbered problem is easy. They are… for you! Expect that kind of outcome sometimes.

Timing!

Next, calculate how much time to give yourself to do the problem set.
