Question: I'm looking to brush up on SAT math. (That's basic algebra, probability and trigonometry.)

I'm interested in books and websites.

Answer: 
I highly reccomend the Princeton Review series of prep books, they have worked wonders for me. The College Board website also has a lot of useful tools, such as a complete free test that you can take online, and sample questions.
