GMAT Avengers Study Group: Graphs & Illustrations:

by on February 20th, 2015

The Graphics Interpretation problems present us with a piece of data in the form of a graph, Venn diagram, scatter plot, etc.

Before we start with a few practice problems, let’s share the links to the BTG articles that we shared on our Facebook Event Page:

Key Takeaways for solving problems that include Graphs:

  1. The Graphics Interpretation questions will always contain … a graph! We may see more traditional graphs, such as pie or bar charts, but you may also see more unusual graphs. As a general rule, read the introductory text BEFORE examining the graph.
  2. Don’t try to understand or learn everything about the graph. Know how it works and what kind of information it gives, but that’s it. We don’t need to take down a bunch … of notes about the details of the graph, though there may be times that we will want to jot down a note about how the graph works.
  3. The Graphics Interpretation questions can be less dense, and therefore faster to answer than other questions.
