I am going to AZCOM (class of 2004). My best friend is an MSII at TCOM and has told me that I need to take both COMLEX and USMLE, especially if I want to do an allopathic residency. I definitely want to do Internal Medicine but have no idea where yet. AZCOM does not require both for graduation. But should I plan to take both any way to "be safe"? My friend also suggested to get a review book early on and tag special topics along the way for easy cross reference later on. Has this worked for any one and if so what review books would you suggest?
