At Western, first year students have the option of doing the ISAC course in the Summer (Intensive Summer Anatomy Course). We only had one student last year who did it, I'm not sure how many are doing it this year.
It basically takes the place of Gross Anatomy and while the rest of us are stressing over Anatomy (being the first course of the year), the ISAC students where taking it easy and causally studying for the upcoming classes. I heard it is pretty tough though, hence the name "Intensive."
