I've been using the Princeton Review's "Cracking the GRE" book and just bought their "Math Workout for the GRE" book, so I will be studying that hard between now and the 18th. Also, for anyone planning to take or re-take the GRE, make sure you get the score you want, because the new rule is that test takers may only take the GRE once every 60 days (it was formerly once every calendar month).
