Math improvement for June?

After taking the SAT and not doing as well as I would have hoped, I took the ACT in April. I have never studied for either test, but I rarely study and figure studying won’t make that big of a difference.

I was relatively happy with my ACT scores (for what schools I wish to apply to): English33, Reading32, Science33 (Fav section), but Math27 so composite 31.

I just started precalc this year and I have a pretty bad teacher. What can I do to get my math up before June (hopefully the last time I will take it). I could also use some general help in all sections. Prep book/studying suggestions??

My goal is composite 33 (or higher!)

The best way to do well on the math section is to review all concepts from Pre-algebra to Pre-calc. Get prep books but make sure that you have fully mastered all the math material
