Any thoughts on Rx flash cards? I won't buy the book until M1 officially starts, but first aid seems to provide an outline of almost everything you need to know for step 1. If you know and understand everything in FA, it seems that you should be in good shape for 90%+ of questions on step 1. (And the 10% of questions that not in FA won't be covered in any one resource, as the possible medical knowledge that can be tested is simply too broad.) So it seem like it may be good idea to purchase the official first aid flash cards to help hammer in the first aid info, as I proceed through classes. If you're already planning on getting the Rx Qbank (which seems to be superior than kaplan to do along with classes, since it helps you learn FA and apparently covers less irrelevant minutia), getting the flash cards and FA videos is around 100$ more. I also plan on doing sketchy micro and pharm along with zanki to help memorize micro and pharm, pathoma along with zanki to help me understand pathology, B&B to help me understand lecture concepts but not directly for step 1, and UW during dedicated. It's a bit silly to plan all this out now, but it's a nice to have an idea of what resources I plan to use for preclinicals + step 1 before med school, with all its demands, starts.
