I took the MCAT in '98 with 33-O (13V 11B 9P). Those scores have expired, so I'm retaking it this spring. From what I've seen so far, the ExamKrackers series is closest to the MCAT format. Te questions are trickier, and they've zeroed in really well on the things that are actually tested. It's also more entertaining, which is the only way I am getting through it. I didn't get their Verbal prep book, but if you practice on the LSAT and GRE verbal sections (for which there are far more materials available), you will be well prepared for anything the MCAT might throw at you.
As for me, I completely lost my composure over the Physical Science section (which is second), and I know that neither the Bio or the writing score is what it would have been had that not happened. I have no doubt that even the verbal would have suffered, had the section been after PS. So those of you who are struggling with verbal--the very first section--I really feel for you.
Again, your best bet is to study GRE and LSAT verbal sections. Particularly LSAT--those are the hardest, and the MCAT will NOT be more difficult than that.
