# How to Beat Overlapping Sets GMAT Problems

**Overlapping sets make for particularly hard GMAT math questions**. While they technically fall into the category of arithmetic—a type of math most people feel comfortable with—the complexity and presentation of overlapping sets problems throw many test takers for a loop.

So how can test takers make sense of all of the complicated information in these questions? And how can we get overlapping sets GMAT problems right every time? **In the new video “How to Beat Overlapping Sets GMAT Problems,” we discuss the number one strategy to conquer these deceptively difficult GMAT questions.**

We start off by defining overlapping sets GMAT problems so you can recognize them on test day: they are **word problems that deal with one large group that is being evaluated for multiple traits**. This in essence breaks our larger group into many smaller groups with different combinations of traits.

We then delve onto our key strategy for overlapping sets GMAT problems: **making a diagram**. This allows us to

**organize information**from the problem.**clarify relationships**between our smaller groups.**build equations**we can then use to solve.

On overlapping sets GMAT problems where our larger group is being evaluated for two traits, we use a specific type of diagram called a “double matrix”, which we explain how to create on your scratch paper. **We also use a real overlapping sets GMAT question to illustrate how to set up our double matrix diagram and then use it to solve**. Finally, we talk about how to set up a diagram for the really hard GMAT math questions in which our overlapping sets involve evaluating for three or more traits.
