Call me naive, but I don't get the idea of Saturday classes, esp. for those schools that are apparently already very academically rigorous, which I'm assuming translates into more homework hours. It seems to me like 5 days of classes plus 3-5 hours of homework 5 nights a week is enough...and that's not counting whatever weekend homework needs to happen.
I noticed once school said that their Wed. and Sat. classes only went until noonish, so perhaps a 1/2 day Wed. would justify a 1/2 day Sat.?
