You'll do a lot of sitting, esp in the morning when people come to talk to you which can get tiring, esp when you're trying to stifle a yawn after a while. but the speakers are both interesting and informative. The school is in the Catholic tradition, but my impression is that I wouldn't worry one bit about not being Catholic or Christian (I'm not) because I just don't think they really care so long as you are a basically good, moral person.
