Do you have to be in a soriority/fraternity to go to lots of parties in college?

Yes. I know all the other people are saying that you don't, but at most college campuses if you want to go to a REAL party and not 10 people sitting around a keg then you are going to be going to a Greek party. Can you get in without being a member? Sometimes. If you're a girl then you have a WAY better chance because its usually the fraternities that throw parties and they will always invite girls, but if you want an automatic invite, Go Greek.
