ACT Math Review Book

<p>I am really good in math but since it's summer time now and I haven't done any real math studying since school ended, I forgot a lot of math formulas and rules and properties and other stuff. Which book is the best for reviewing ACT Math? I was considering actually studying from the Barron's Math 2 SAT Subject Test book but I am not sure if everything in that is needed for the ACT. I have the Barron's 36 book but it doesn't review any material. All it tells you is that you need to know something but it won't teach you exactly.</p>

<p>So which book is the best for reviewing ACT Math? I got a 30 on math on my last ACT test so I don't need really basic math help. I just need help with like trigonometry and geometry mainly.</p>
