SAT and ACT Prep

Hey all,
I really want to do well on my SATs and ACTs, so can anybody tell me the best ways to prepare for SATs and ACTs. You know, websites, books, etc. Something understandable would be good.

@AmbitiousGecko in general, using official sources for practice tests is a good idea. However this topic has been discussed frequently; search the SAT and ACT subforums for more info.

Just practice the tests and keep a record of the questions you get wrong. Take those questions over and over until you can get most of them correct. It is more practice, than study. Best of luck! (Kahn Academy has some free practice questions on the Internet for the SAT.)
