How to get a perfect SAT score?

Well I didn't get perfect score (I got a 2340), but maybe if I pushed myself a little bit harder I could've. But I basically took a couple of preparatory couses and had a personal tutor. I also got the Big Blue SAT Study Guide from College Board and studied the whole thing several times. I also got the SAT Vocabulary list and memorized all the words for the Critical Reading section. And finally I took many full-length practice tests, timing myself. Also I practiced doing essays and had my english teachers read them.
