My student host gave me a glimpse of her schedule and it's pretty much classes/labs/OMT etc 8am-5 pm. She says she treats it like a job. The school makes the schedule on Microsoft Outlook and shares it with the students so if there is a sudden change (i.e a professor can;t make it to class) it will reflect immediately on the Outlook schedule. The day of my interview she actually got a class cancelled and they moved another lecture to replace that class... and she knew about it because she checked the schedule right before class.
From what I recall, MS1 students have lectures in the mornings, a break, then lab in the afternoons. By lab I mean anatomy, or OMT, or patient interviews. (Correct me if I am wrong people)
Also, either Thursdays or Fridays are reserved for test days every other week. You test the whole day. In the morning your have your lecture exam (say 8-12), then a 30 min break, and in the afternoon you have your anatomy practical (also 3-4 hrs long).
