Be creative in the dining hall. You will never find so many excuses for a bucket. Make sure your alarm clock has back-up batteries. Duct tape heals all wounds. Showers become less important.
Sleep becomes more important.
Two meals a day are standard. If the lecture hall is big enough, get someone else's notes. T.A. used to stand for teaching assistant, now, for terribly articulated. E-mail becomes your second language. Frat parties are exactly like they are in the movies.
