I used the Kaplan book and made what ended up being a few hundred online notecards out of its terms/people. I didn't think of it until it was too late, but if you do make notecards online, you should use a program that allows you to access them through an app for your smartphone or tablet; I think StudyBlue does that. The Kaplan book comes with two practice tests, and you'll also get one in the mail from ETS when you register. Aside from all having different numbers of questions, they accurately reflected the real test and were very helpful. I scored in the 96th percentile, so putting in a real effort for all of those things was definitely worth it!
