Current M4 at AZCOM, just matched! Keep in mind some things may be different from when I was in my pre-clinical years.
Things I like: Felt like I received an excellent education overall. Administration is pretty hands-off 4th year, which is nice. Near 100% recorded lectures, with very little mandatory attendance outside of OMM and Introduction to Clinical Medicine (ICM). They do a very good job preparing you for the Level II PE. They have a system for rotation reviews, so you can log onto computers in the clinical education department and easily find rotations that are great for learning (or for blowing off) or avoiding rotations w/ malignant preceptors.
Things I don't like: Exam every single Monday. Too much OMM. I hate OMM. 4 hours minimum of OMM every Wednesday. Finals weeks were ALWAYS scheduled poorly. Administration always seems like it's out to get you, but that's probably the case at every school nationwide.
Rotation structure: 4 week blocks. 3rd year: 2x FM and IM, 1x peds, cards, surg, rural, elective, OB/GYN, psych. 4th year: 2x vacation, 1x EM, ICU, IM subspecialty, surg subspecialty, fill in the rest w/ electives. You are assigned to a region/cohort, and all/most of your rotations will be in that area/hospital. Most (80%) stay in Phoenix area, but you can also go to Chicago, LA, SD, and Prescott that I know of.
Overall, AZCOM is a solid school. Most of my classmates, including me, have a fair amount of bitterness towards the school. It's absurdly expensive, and I've heard horror stories about deans and clinical department heads being complete a-holes to students. The fact is, though, that I have received a good education here, and I would definitely choose to come here again. Just do your best to avoid the administration.
