June 18, 2013 by

Welcome back. As I mentioned before, each week we are going to feature a problem breakdown here on the blog. Last week we dove into probability. We’ll revisit that topic in the weeks to come. This week we are going to start moving into combinations and permutations. These can be some of the toughest problems on the test. However, since I can feel your pain on this topic, we are going to start slow. Instead of diving in, we’ll start by getting our big toe wet first, or maybe our little toe. For those who are at an advanced level on this topic, check back in a few weeks. We’ll be up to speed and breaking down some tough GMAT problems. For now, let’s use a problem to get a feel for how we handle these things.

Problem:

Kim has four trophies, which she wishes to display in a … Read full post

# GMAT Math Shortcuts: Dividing by 3
