Here’s How to do GMAT Unit Conversions Like a Pro

by

blog-metricsSometimes 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

Here’s why you should interleave your GMAT studies (and what that means)

by

Blog-InterleaveRecently, 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

Try this problem from the GMATPrep free exams. Read more
