The Content of the Math Test
The ACT Math Test covers a broad array of topics,
from simple topics like prealgebra to more difficult ones such
as trigonometry. You shouldn’t assume that the prealgebra questions
will be a thousand times easier than the trig questions, though.
To compensate for their relative difficulty, ACT usually uses the
basic format to ask you questions on trig. Prealgebra questions,
on the other hand, run the gamut of difficulty, so don’t slight
them in your math review.
Below, we’ll run through the entire content of the ACT
Math Test, listing topics according to mathematical subject area.
We won’t bother describing the topics here because the majority
of this section is devoted to reviewing all the concepts in depth.
Don’t panic about the length of this list: its length actually benefits
you. Because the Math Test covers many topics, it can’t devote more
than one or two questions to most of them. So if you completely
blank on the rules for perpendicular lines, you won’t lose a significant
number of points—especially if you guess well.

Also, note that this list covers all the topics that could,
not all the topics that will appear. A number of
these topics will not appear on the ACT you take. That doesn’t mean
you shouldn’t review, but it does mean that you shouldn’t worry.
As part of our review of ACT Math, which takes up the last two thirds
of this section, we will tell you which topics appear often and
which pop up only occasionally.
