ACT Math Test Content

Before you take the ACT make sure you read the information they give you on each of the sections! Here is what the ACT tells us about the math, “translated” into normal English.

The ACT will always allot the Math questions the same way, with each type of math content having the same percentage of questions from test to test.  If you have taken Algebra 1, Geometry, and Algebra 2, you should be in good shape.  They do have some topics that are occasionally covered in pre-calculus, so you may want to wait to take the ACT until you have covered all the material.  No need to worry about calculus – that won’t be on the ACT.
