Are you majoring in software development/software engineering?
If yes:
Enjoy never seeing friends, spending hours inside a computer dungeon working on code, wondering why your shit doesn't compile or has errors or returns null.
You'll spend four years going to hack-a-thons and Smash Brothers tournaments, play League of Legends, get really hipster software shirts that say things like "if (drunk) { do shit } else { self.getDrunk; }".
After four~five miserable years, you'll get an amazing job offer, and you'll cry tears of joy as you drive away from your unemployed alumni who claim they're going home to "rest before doing the after college job thing".
If you're majoring in anything else:
You'll have a bitching time (unless it's engineering, then your shit's gonna suck about the same as software majors), you'll party, you'll have fun, you'll go abroad, you'll go on spring break trips, on campus parties, you'll drink with friends, you'll do stupid shit in dorms.
Then after four or five years you'll be unemployed as fuck and you'll feel like a dumbass for pretending business administration or economics or whatever was a solid major choice and that "every major can get a good job if you love doing it" etc.
Getting laid:
Once you figure out your demographic, you'll have a much easier time getting laid. Girls in high school want to have sex but they're afraid of sex reputation. Basically they get labeled as a whore for having sex. But in college, they learn that not every guy runs around telling all his friends like a fucking idiot that he had sex. If you can say funny shit, try to close, shower up and clean up nice and keep your fucking mouth shut about who you take home and who knows about it, you'll get laid all the time.
Also figure out your demo.
I'm a 5'7" Hispanic, former hip hop dancer, engineering graduate who plays beer pong and goes on hikes. I have no fucking business hitting on blonde sorority girls or hipster cafe employees. But hitting on Asian girls? I can close like 85% of the time.
They can't be super hot white washed Asian girls though, those girls dig white guys.
Knowing who you are successful with is most of the game.
