You will have plenty of time to study and have a great college life. A few things I learned...
1) Never schedule a class which conflicts with happy hour.
2) Weekends start on Thursdays.
3) If you need an 8 am class for your degree, then you should change your major.
4) Fraternity parties are everything you thought they were.....and a whole lot more.
5) It is thought that alcohol consumption and GPA have a inversely proportional relationship.
6) On move in day, offer to help people move into the dorm, especially the opposite sex. This always helps you getting laid.
7) Even if you aren't into greek life, you should rush. The free beer/titties in your face comes only once a year.
8) Take introduction to human sexuality or some similar course. It's a free trip to the strip club and it's for school credit.
9) Save your tabs from canned beverages, they can be traded in for a keg.
10) If you are starting college with a high school girlfriend/sweetheart, do yourself a favor and break up with her.
