Also, and I can't stress this enough... if you're just going to class, you're not learning anything. Your classes won't prepare you for life after college. College is a networking opportunity. You'll want to make as many connections as you can with people on and off campus, do internships, do independent research, etc.
What's your major?
Find a minor, too, and get more involved on campus. If possible, see if you can get an internship for the Winter recess.
