Hey! So currently the schedule changes based on the day, but you can usually count to be in lectures from 9am till 3pm (with an hour lunch break 12-1pm). With this semester we have had an increase in the number of labs so far. Those are scheduled based on groups that you are assigned to. For example, if the school sets aside time from 8am-12pm for labs for the entire class, but your group is scheduled from 8am-9am, then you get the remainder of the time to use as you choose (be it studying, sleeping, mental wellness, what-have-you).
As far as the blocks go, it is more about focusing on 1 topic at a time. For musculoskeletal (which we are wrapping up soon), we go over everything pertaining to the musculoskeletal system including pathology, radiology, anatomy, normal cellular function, pharmacology, etc.
