First year at DMU here.
Unless the day has a lab, it generally goes from 8am-12pm, give or take an hour. Wednesdays are a short day, most often from 10am-12pm.
Labs for anatomy were 3 hours long, my lab section was once a week from 1-4.
This semester it's physical diagnosis labs, 2 hours each, once a week.
Every exam except I think 2 have been at 8am, those two were at 10am.
Nothing Saturday, ever. Nothing Sunday, ever. Except studying, every weekend.
At this point I've realized that you didn't mention applying to DMU, so I don't know how helpful this will be, or how university specific you were looking for. Either way, I doubt the other schools will have much more than this, so you can probably consider it a safe mean.
