GED Math

About the test: The GED math test covers Pre-Algebra, Algebra, and Geometry. It is administered on the computer and is timed.
Calculators: There is also a calculator provided on the screen during the test. It will be very similar to what you might have on your phone (not an app, just the basic calculator function) or as the one on your computer. You will also be given a reference sheet with basic formulas.
