I'm not sure which schedule you're referring to so I'll use an example from our cohort's last September schedule (Term 1).
So last September (2017) for first 3 weeks: (with an assumption that lab was at 8:30-10:30)
Monday: 9-4 Tues, Weds: 8:30-10:30 lab, Thurs: 9-4, Fri: 8:30-10:30 lab.
From 4th wk, an example with Tues, Weds Clinical:
Monday: 9-4, Tues, Weds: around 6:45-3pm (depends on every clinical group but generally 7am-3pm), Thurs: 9-4, Fri: 8:30-10:30 lab.
If Clinical was Sat, Sunday, you got Tues and Weds off but same time on Sat, Sun around 6:30/7am-3pm.
For term 3 that we start from next week, some of us have 2x12hr shift while the others have 3x8hr shifts. The only thing that I personally know about term 3 right now is that we have class Mon, Tues from 9-4pm and have labs for 1st 2wks. I'm not sure what our lab schedule is going to be from the 3rd week since we haven't started the term yet. I hope that helped to answer your question :)
