For STEP 1 I used Sketchy Medicine (Micro, Pharm, and Path), BRS Physiology, UWorld, First Aid, Pathoma, and Pastest. I did a through review of everything using sketchy, BRS, FA, and Pathoma. After each system I would complete that systems questions in UWorld. After I got through UWorld once I used Pastest and UWorld together. For 2.5 weeks before the test I did an average of 150 question a day. Pastest was great to mix things up from UWorld and keep you on your toes. I highly recommend trying to memorize the high yield concept at the end of FA. I hate memorizing but that information was extremely worth it.
