This information is from Mrs. Borowski.
Included are some sample calendars, or pacing guides (as "educators" call them), to help you prepare for the ACT. If you investigate the first three listed below, you can see how students all over the world spend an hour or more a day prepping for this test.

Read the information. Experts suggest focusing on your two lowest scores predominantly.
This is a score chart that may help you see how many questions you get right will translate to what score.
A Google book. It includes practice for the ACT and SAT. Do both.
Bottom line? Attack the test as if you were attacking a game plan for a state championship game. It's that intense.
Good luck!
