I found the Qbank to be somewhat harder than the real MCAT. I did not find it conducive to preparing for the MCAT because it made me feel like I didn't know anything. Also, there were problems with some of the passages, like figures not showing up right and some answer choices did not match with the questions. I don't remember which ones but there were a couple. I used it to prep for the April 2006 test so the mistakes might have been corrected by now.
