1. Dorms suck (Assholes and loud annoying fucks for me, not the restrictions on drinking)
2. Get sleep. There's no reason to be staying up the whole night unless you either a. Didn't attend lectures b. Never did anything up until studying til the night before. Your body and mind will thank you later.
3. It's nigh impossible to know what you really want to do going into college, but think ahead and don't pick something unless you're really interested in it. Also, if you don't do that don't be afraid to change your majors. I was in construction engineering my first year, and it turned out to not be at all what I wanted to do. I switched to Psychology right after, and my college experience improved tenfold. I help proctor exams and do miscellaneous things around the Psych department occasionally now as well.
4. Do something outside of class/fun. I've never done clubs, but do anything campus related. I've worked at a new renovated, pretty small dining center for two years now, and it's decent pay along with meeting a lot of new people. Find something that involves yourself with others that you can expand with.
5. Whatever your major is, get involved with it wherever you can. I had a Psych professor that I really enjoyed having in a class, and she needed students for her 491 Lab. I'm now in my third semester with it running experiments, entering data and analyzing some of it. It's really awesome, and I love doing it.
