Two questions: 1. I have my exam coming up in about 4 weeks. I study first aid, BRS path, BRS phys durring the day then do Kaplan QBank at nite. Many of the Qbank questions ask about things not mentioned in any of these books. Thoughts on those questions from which the material is not mentioned anywhere else? How well should I study that info? 2. Do you think getting USMLE world in addition to kaplan is a good idea? I think I'll have the time later to do more questions. ANy thoughts about USMLE world in general?
