One thing that really helped me out early in the college career was to make friends with EVERYONE on your floor and recognize people in your classes that may live a building across the street that you see often or people on floors above/below and work on homework TOGETHER! There are so many instances where you have 4 or 5 people together working on homework and you can work through problems that you may not understand fully or better yet, help someone understand a question/topic/theory and in greater you learn it in more detail. The same things are for tests, get with that group of people cause you'll likely take many of the same classes your freshman year and some further through your major.
One thing I always remembered was "learning communities" the kids I met there I had classes with all the way through school so they were there for homework/quizzes/studying/etc.
That's the school part of it
The life part of it,
Go out the first weekend there with a backpack of beer and go with a bunch of guys/gals from your floors and hit up some big parties either through friends siblings or whatever. Girls are trying to fit in especially well that first weekend and it is FUN! Attend as many football/basketball games as possible. Basketball games will pose a conflict with test/lab or something through the course of the year, don't miss test or lab, they really do count quite a bit towards your grades. If you have a family member that tailgates in the North or East lots tailgate with them at first, not as many cops and you can drink heavily inside a camper or bus. Enjoy parties on your dorm floor, but keep the music down and the yelling to a minimum. We got busted far too many times for the above mentioned.
Join clubs, of which I didn't do much of, but I wish I would've done more so of. Also, college is a fun time of your life but remember the major you choose in college is what you are going to more than likely do the rest of your life. Enjoy what you are going to school for, or you are in the wrong major. I didn't necessarily enjoy doing homework any more than the next person, but I did enjoy learning more and more every day about construction, equipment, etc. and it's made my career now enjoyable every day I go to work.
That's more school part of it.
