Hey guys, I apologize for neglecting to follow up on the responses for so long. If it is still pertinent, I found gmathacks.com the most comprehensive set of material available (if you struggle in math, I can't recommend his study guide highly enough- and I assure you I have no affiliation with that site), and what I used for 70% of my preparation. The rest was probably 25% Official Guide questions, and 5% Kaplan 800.
