I learned more in college than I ever had before college, although a lot of what I learned was life skills and not at all involving classes. i found the workload to be very heavy and the professors to be mostly very supportive, but then again I was in the college of music and that's a whole different experience from "regular" stuff perhaps.

definitely have fun, party, hang out with people. just be sure to learn how to balance work and pleasure. don't fail out because you are drunk constantly, but also don't burn out because you never do anything but classwork.
