What is the best way to study for ACT Math?

I am in desperate need of advice. I am taking the ACT two more times. Right now I have a 23 and I am aiming for a 28. I am taking the test September 9th and October 28th. I keep on averaging a 23-24 on the ACT math practice tests I am taking and it is ridiculously frustrating. What is the best way to study? I don’t have a lot of time, only about two months. I’ve been studying for at least three hours a day in the library and at home, my score isn’t going up. Please lend me some advice, it would mean the world. Thank you!!!

I honestly pulled out my pre-algebra books from middle school. I also studied topics on khan academy. A lot of the material (especially the hard questions at the very end of the math section on every ACT) was covered in my pre-calculus class. Actually, I ended up studying the very same concepts for the June ACT and some final unit tests in my pre-calc class.

Other than that, take as many practice tests as you can.

I’m taking pre calc this year, hopefully it’ll help me out too. On my practice tests, I’m averaging a 24-25 (On math Math ACT). And for my goal, to get a 28, that’s actually fine, but I would need to get a 25 on my science and 30’s on my English and Reading sections. The reading is going to be a bit difficult for me to get to a 30, so that’s why I’m trying like heck to bring my math score up. Thanks for the tip!
