Except for the fact that you and your parents are paying obsene amounts of money for you to get a good education.  Don't fuck up and drink every night, then start falling behind in grades.  You can party, but be responsible, and always put your school work first.  Also if you have any ideas for graduate schools, you'll need very good grades for that.  If not, I'm sure you'll want to get a good job out of college, and if you want to do so, then you'll also need very good grades.  Don't be an idiot, college is one of the best opportunities of your life, so don't fuck it up.
