Remember these things:
Spades is a card game, not a major/minor!!! I've known quite a few students who were in danger of being on academic probation b/c of this.
If you can trade books with other students at the beginning of each semester, do so. That's better than trying to sell your books back to the bookstore and getting less than 50% of what you paid for. Damn those professors who write the textbooks and make changes to them each semester.
Definitely join a club/organization, especially one that will pertain to your major (NABA, AMA, etc.)
Study first, party later. I've never know schools to hand out A's to students who attended every party that was held.
Get to know your professors!!!!! You will need them on your side when it comes to final grades and letters of recommendation for grad school.
NO CREDIT CARDS!!!!!! THEY ARE THE WORKS OF THE DEVIL I TELL YA!!!
