Question: Do GRE prep classes really help? Do you think I can do the same thing with a book? I am contemplating signing up for a GRE prep class, but they are so expensive. I am kind of worried about my scores, so I'm just not sure. Does anyone have any experience with the courses? What do you think? Thanks.

Answer: a book is good enough if you have the motivation and discipline to study regularly.  What a prep class does is give you structure to study regularly and do your work.  It's more about establishing a schedule than what they actually teach you in the class.
