PowerScore GRE Forum Featured Post: Overlapping Groups and Venn Diagrams

The Six-Point Path to SuccessVenDiagramquestionexsit.png

From time to time, we like to feature questions and answers on our GRE forum because many of these discussions can be helpful to other students as well. This post responds to a student question from an older, retired GRE practice test. Before we dive into the specific problem, we discuss the principles of overlapping groups and how to use Venn diagrams successfully. 

Instead of "cutting to the chase" with the math, we discuss the principles/relationships that underlie overlapping groups. The discussion illustrates how given some information, it is possible to determine most or all of the missing information.

While this subject can be challenging at first, it is an excellent example of the importance of Recording What You Know, getting your scratch paper set up effectively with the information you start out with. With the relevant information in front of you, it is often considerably easier to notice the path forward to the solution. In addition, instead of feeling frustrated or confused, by using your initial time to set up your scratch paper, you can keep your momentum moving forward, doing something productive that moves you closer to the answer.
