Mostly monday through friday 8-5, with intermittent down time. Wednesday is lecture all day, 8-5. M, T, TH and F have labs and since you'll be broken down into two sections, you'll have some down time while the other section has lab, so 1.5 to 3 hours of down time sometime between 10am and 5pm on those days. If you're lucky, it'll be at the end of the day and you'll be done by 2pm.
