Are there a lot of monday tests, where the games and possibly a little tailgate before might really mess with study time?
We have an exam pretty much *every* Monday morning.
Fall semester of 1st year is relatively easy, so you'll probably have every third Monday free of tests during that semester. But every semester after that, Mondays are for exams!
It's really not as bad as it sounds, though. If you make a decent effort at studying during the week, I think you could afford to take a day off on weekends for enjoying the game. Just don't fall behind.
I think the summer Anatomy will give you a good idea of how much time you will need to devote to studying to do well.
I also recommend buying the scribe notes, because I eventually decided it was a lot more efficient for me to learn by reading the scribes rather than listening to the lecturers since I can read faster than they can talk (with the exception of any lectures that involved a lot of photographs, like the histology or pathology ones).

choose a semester and click "Weekly Schedule" in the "Semester Resources" box you can see what our schedule of classes and exams has been in the past, to give you an idea of what you'll be faced with.
Good luck! It's a great school and I have been happy here, so I think you'll be fine!
