how difficult is the ACT math?

So I've been practicing for the July ACT, specifically the math section, using the ACT prep book (2024-2025), and I've found that the practice problems are relatively straightforward and not extremely difficult, but I started doing some online practice problems and tests (not created by the ACT), and I found those were really hard. So I was wondering whether the math problems in the act prep book are similar to what would appear on the test.

Also I have taken Algebra 1 & 2, and Geometry. I haven't taken precalc yet.
