I go to a 3 year school. Class was about 8-12 year 1 and 12-4 year 2. About 4 hours per day, but occasionally there's a lab or some other BS thing that keeps you a lot longer, but then there's also shorter days so it all balances out. Our quarters are 10 weeks long plus a week of finals. I always told myself I would study a lot the first week, but never did. At 10 weeks though, quarters seem to go by so fast and then you get a week off every 10 weeks and if you don't have a lot of finals it always feels like a 2 week break (a lot less finals in year 2) plus there's an additional 2 weeks off at Christmas time and new years. About 4-5 weeks off in the summer. Not bad at all when you add up all the holidays that give you 3 day weekends or even 4 days (Thanksgiving) during a quarter. Way easier than undergrad since the material is easier. Yes you have to cram, but at least at my school if you get a hold of last years test, they use the same questions! For example I got a 100 and a 95 on the 2 oncology tests that everyone was freaking about, but average test scores are always in the 80s, many times high 80s, and I think it's because people with last years test questions have extremely inflated grades and then everyone who doesn't have old tests gets Cs. 2 people in my class got held back a year, but no one ever flunks out because the remediation policies are crazy lenient. 70 is passing, but if your final average is 60-69 you have the option to take a test, basically a cumulative final exam, and if you get at least a 70, you pass the class. Most people don't fail by more than 10 points and you have a whole week off to study so most people never have to repeat the course in the summer. You can do that 4 times per year. People that get held back it's always over something weird like one girl skipped all her finals and another never went to class. If you have decent time management skills you definitely have time to workout everyday and go out at night whenever.
