I just took the Princeton Review class and I'm glad I did. The manual that comes with the class is so-so except for the Bio, which I think is excellent. As far as classes go, it all depended on who was instructing. My Bio instructor was awesome since she allowed us to show up to her MCAT bio class since three bio classes were defintely not enough. O-chem and Gen Chem were so-so. PAT problems weren't impressive since some of these would show up also on the diagnostic tests. But it gave me motivation to study and hey you can ask around about application, lor, etc with other students. And you also receive the Top Score Pro CD ($50) while still paying $400 less than Kaplan.
