Sample Testing

Want to know how prepared you are? Take a test. We have an unlimited number of tests, and you can take a full-blown GMAT computer adaptive test, with 37 questions, or you can take smaller tests with as few as 12 questions.

If your pre-algebra is pretty good, but you want to see how you’re doing in coordinate geometry, then you can take a sample test in which all the problems are from coordinate geometry. In fact, you can take a sample test in any of the 6 individual ACT math areas.

We time all the tests (but you can ignore the time if you choose), and we’ll show you the results with the proper solutions for all questions afterward.
