You’re staring at a GMAT problem that you just don’t understand. There’s a minute left on the clock. What do you do? Read more
Sometimes the whole point of a specific GMAT problem is to convert between miles and kilometers, or meters and centimeters. In other problems, you’ll need to do a unit conversion as part of a longer solution. It’s easy to mess up unit conversions, and the GMAT writers know this — they include them on the test in order to test your level of organization and your ability to double-check your work. Here’s how to add fast unit conversions to your repertoire of skills. Read more
The GMAT Critical Reasoning question type “Explain a Discrepancy” has a very specific goal. If you know what your goal is, you’ll be much more likely to answer the question correctly. If you don’t, it can be very easy to get turned around and fall into a trap.
Try this problem from the free questions that come with the GMATPrep® software and then we’ll talk about how Discrepancy questions work! Read more
You may have heard that, on Monday, some GMAT students started receiving emails inviting them to take part in a Select Section Order Pilot program that GMAC (the organization that makes the GMAT) is holding in late February/early March.
This pilot is to test an awesome potential new feature: the ability to select the order in which you do the various sections of the GMAT!
Below, I’ve laid out all of the important details and I also talk about how to decide whether to join, if you were one of the lucky students invited to take part.
How does the pilot work? What are they testing?
There are really only a dozen different Critical Reasoning problems in the Official Guide to the GMAT. The test writers recycle the same basic argument structures over and over, and they use the same right answers over and over, too. Even though the topics change — an argument might be about school funding the first time you see it, and industrial efficiency the next — you can sometimes recognize the underlying structure, outsmart the test, and earn some well-deserved points on the Verbal section.

Recently, I wrote a post about how to get the most out of Official Guide (OG) problems during your studies. In that article, I discussed the concept of Interleaving your studies and I’ve got more to say on this strategy that’s of crucial importance to your studies.
What is Interleaving?
In a nutshell, interleaving is a way of mixing up your studies. For example, let’s say that you’re about to start studying the Fractions chapter of our Fractions, Decimals, & Percents (FDP) Strategy Guide. It’s only 8 pages long, so you should just read the whole thing straight through, right? (Note: if you actually have this guide, pull it out right now and follow along below.) Read more
The beautiful thing about Data Sufficiency is that we’re allowed not to do all of the calculations that a Problem Solving problem might require. Still, leave it to the GMAT to try to suck you into doing more than you need to do in order to get to the answer.
Normally, I just toss you into a problem and then we discuss, but today I’m going to warn you: the GMATPrep® problem that I’m about to give you is going to do its best to make you waste time. As you try this problem, ask yourself, “Do I really need to do that calculation? Is there an easier way?”
Try this problem from the GMATPrep free exams. Read more
Over the past five or so years, I have seen more and more students take the GMAT twice.
Let’s talk about GMAT Data Sufficiency.
Specifically, let’s talk about getting GMAT Data Sufficiency (DS) problems wrong. And I don’t mean those problems that you missed because of careless math errors, or because of concepts you hadn’t learned yet. No, I’m talking about the missed DS problems that make you want to bang your head against the wall: How on Earth did I not get that?
There are two reasons you might have this experience: Read more
