Need help with a General Studies Book

[2canSAM]

I am going to college after 10 years out of high school. I want to do good on the Entrance Exam but need to brush up on a lot of the basic skills that were taught for a "General Studies" student. I was in the Advanced Program in high school but there is soooo much that I don't remember. I need to know what books you guys could recommend to review Math, Algebra, Calc, Chemistry, Biology, etc. I guess I could get some high school text books but have no idea where to find them.
