Might as well throw in my 2cents on rotations:
Peds: Did it at CHM like pretty much everyone. In patient peds at CHM is pretty good and just about every student I know enjoyed their experience despite the Q4 call. Outpatient peds at CHM sucks because most of the time you are at this "clinic" that is complete chaos and you are pretty much just in the way. That is when you are not going to a million lectures. Bonus Tip: Read Dr. Friday's review packet it's great for the test. Immunization schedules/development will only be like 2-3 questions on the exam.
IM: Did it at Oakwood and loved it. I had more patients than most of my friends at other locations. They have a huge emphasis on teaching there, which is evidenced by their super high board passage rate for the residents. They treat you like a collegue and not a scutmokey/punching bag. Saw lost of bread and butter medicine like CHF, COPD, etc. which shows up on the test. Good hours, good residents. You name it, it was great. I'll be doing my sub-I there next year I liked it so much. I personally would stay away from DRH, as I have only heard bad things about medicine there. Bonus: MKSAP3 is awesome, will prepare you well for the exam.
Family: Horrible experience, but that was because my preceptor was very bad. I'm not sure if they even send him students anymore. Most people loved this month.
Neuro: DRH. Long hours (no call) and marginal teaching, but they let you do a ton. I learned so much on this rotation just because I had personally done the consults on just about every major neurological problem. In fact, by the end of the month I had seen just about everything in my neuro books I was reading from. Bonus: I heard that Dr. Fakouri will honor you if you honor the exam, I think this is true from my experience.
Psych: Do it at the DRH crisis center. This is the most laid back location. Very low stress and fun. Dr. Ajluni in the crisis center will let you do a lot and teach you all sorts of good stuff. Super nice attending, in fact, he won the Staff Award this past year. Also, the clinic at UPC Jefferson is just as chill. Bonus: The OSCE with Dr. Spurlock is basically your entire clinical grade. When you present the patient you interviewed to her, spend your entire 20 minutes talking. Present the patient, then immediately go into your differential dx and the DSMIV criteria for each one and why you would or would not consider it. Then talk about the treatment plans. The more you talk, the less time she will pimp you on stuff you probably don't know.
Surgery: DRH/Harper. I personally liked the month at Harper better than the previous posters. The hours are long and you only get 1 day a week off, but you see a lot of general surgery stuff. Days typically 6-5. DRH is better in regards to hours since you usually get out in the early afternoon on non-call days. Others like DRH for the trauma, but otherwise you don't see much surgery. The case volume isn't that high. Henry Ford is better in my opinion since you get your weekends off when not on call, they have a huge case volume, and you get an entire month of electives.
OB/Gyn: Ford.... only time will tell as I have this next month.
