I've done all of the Princeton Review, Kaplan, and OG 11th edition problems, reviewed my answers, redid the problems I got wrong, and took several full length practice GMATs.
In the next two weeks, I plan on working on some concept I've been struggling with and doing 2 more GMATs.
My question to those who already took the GMAT - how did you prepare during the last two weeks? I can of course continue doing 30-40 problems a day like I have been doing, but I'm afraid I'll burn out at the same time. I believe you can "overstudy" for something - which leads to over-analyzing problems, and then getting it wrong (yes, this has happened to me before!).
