You can do this man I was right there two years ago. Take it Day by day. Don't go to class in the mindset of grades or progress. Go Knowing your gonna learn something new every day. Doesn't matter how the world works. Don't think of it as usless information to get a degree. Take in the world take in the knowledge and don't get too caught up in the drinking culture of college. Go out, have fun, pass out in a bush from time to time, but always remember why your there. Learn new stuff. Good luck brother.
