How can I start studying for the SAT? All suggestions welcome!?

At first, do a lot of practice problems. Then sit down and take full tests. After a taking a few full tests, begin to time yourself so that you will know how to pace yourself. I used a book from Kaplan. I wasn't too excited about my score after my first try, so then I tried an online SAT tutor-type thing with Kaplan (if you don't want to spend 100s of $, however, don't bother). That was basically just more practice problems with tips on what types of questions there are, etc. On my second try, my score was raised by 150 points.
