Hi,
I don't think QBank is even worth the promotional $30 I paid for it last fall. A big portion of the 1000-or-so questions they advertise is actually AAMC practice tests I, II, III, IV, V, and I believe VI. You may want to check the availability of accompanying solutions because I only remember seeing AAMC II solutions. Also, there may be difficulty displaying fonts, symbols, and figures accompanying the biology, chemistry and organic chemistry passages and questions. Kaplan's prompt customer service and dedication to improvement nonetheless surely extends to QBank. My humble advice is to spend your money on paper-based as opposed to computer-based practice materials.
