I got a 1410 on it my sophomore year mid year. I found that the amount of reading I do on a regular basis helped immensely.

That link was very useful. There are many tests and vocab boosters that really help out. Just browse through while you Chief Delphi, and you'll be having twice the fun!
I agree with Ryan, the SAT is rapidly losing credibility. However, keep in mind that many scholarships have certain level SAT scores and if you want to have a better chance, a high score is a good booster in the whole deal.
