Q:
# Do you have to be able to calculate percentages to get a GED?

**As of March 2015, some GED sample test questions reference percentages, although the testing agency does not specifically state that test takers must know how to calculate percentages.** The GED addresses the same basic math skills that high school students learn prior to graduation, including concepts from algebra and geometry.

A formula reference sheet is provided on the day of the test and includes common mathematical formulas, such as the formula for a circumference of a circle. Test takers can use a calculator for most parts of the Mathematical Reasoning section of the GED, but hand-held and embedded-screen calculators are not allowed for the first five math questions.
