3rd years vary quite a bit from school to school. Ours is currently 2 months med/surg/peds, 1 month fm/psych/anesthesia, 2 weeks neurology, and 6 weeks ob/gyn. The remaining month is elective/vacation time.
There is really nothing that we're missing compared to the norm. Some schools have 3 months of surgery or medicine, others have 2 months of family medicine/primary care compared to 1, and yet others just have shorter 3rd year schedules (so they end in April or May rather than June and have longer 4th years). (It really does vary. Many schools don't require any neurology at all. A good dozen medical schools, most in the northeast, don't even do family medicine, just preferring ambulatory IM or peds. I think our 2 months of peds is on the longer side compared to a lot of schools too)
As I said a page or two ago, they are also currently in the process of reforming the 3rd/4th year requirements, so it should be a bit different by the time current applicants get to it. Anesthesia might actually be shorter (2 weeks as opposed to 1 month), but they'd move a lot of the current didactic components in it to a different part of the 3rd year. Neurology might be longer (4 weeks as opposed to 2), but students would have the option to push it into their 4th year and increase the elective time in their 3rd. There's a number of other things that they're in the process of reforming.
