The Revised GRE is guaranteed to have some Data Analysis questions. These GRE questions can take several forms: tables, graphs, charts, etc. They can appear in one set, or with multiple figures. You can find some examples on GRE’s website here. To do well on Pie Chart (also called Circle Graph) questions, you will need to follow these three tips for better scores!
Tip #1 – Examine the pie chart fully before reading the question. Read the heading of the chart first, and then look at the labels for each “slice” of the pie. What can be readily inferred? Keep track of the units, and make sure there isn’t any additional information printed below the chart that may be required to solve.

Tip #2 – Don’t equate percents with numbers. The pie chart may display a percentage only, while the question may ask about an actual, “real-world” number. Don’t conflate the two.
Tip #3 – Use estimation and approximation as much as possible. Round numbers up or down to make the math easier. Just like in other GRE Quantitative questions, the answer choices may be far enough apart so that it is easy to estimate. Rounding to the nearest whole number if usually the simplest way to solve, then proceed with the actual computations as you would normally.
