I am about to start. Any suggestions on how best to do it? Any suggestions on books, courses, or anything else is greatly appreciated.
I got a book with a CD and just did a bunch of the problems. My study regimen was not very hardcore, though. I did like having the CD over the book, though, because it helps you get used to the mechanics, the scoring, and the pace. And, you can start your studying by taking the test all the way through and get a good idea of where your weaknesses are. The math is easy -- highschool math -- but they do a lot to try to trick you into dumb mistakes. I found I had forgotten a lot of my high school math and had to read large sections of the book to reacquaint myself with geometry, probability, etc. The verbal seems very easy to me, but that's the kind of thing I'd excel at anyway. I hardly studied at all for that section. It's just grammar, reading, stuff I learned in elementary school.
I took Princeton Review, and it raised my (practice average) score by about 30 points. Yeah, not the biggest jump, but I did score well in the end. If anything, the class at least forced me to study hard and allowed me to become familar with the type of questions asked. Plus, the free Wall Street Journal and Time subscriptions were nice, too.
