These all sound like good resources, but you really need to put in a minimum of a couple hours a night for at least two months...that seems to be the minimum study time that all my classmates who passed put in. I seriously would reschedule if you are not able to do that, especially in light of this being the last time you can write. Prep classes can be useful, but they are no substitute for doing hundreds, if not thousands of practice questions before hand. Doing practice questions will help you identify your areas of weakness. Each question you get wrong, look up the topic and quickly review anything not explained in the answer rationale. Mosby, Lippincott, etc...all of these have answers with rationale, and this is key...you need to read and understand the rationale of every question, especially the ones you get wrong.
