My tips for doing well with girls in college:
Campus Crusade for Christ, or your colleges equivelant, is a good spot to meet girls. All the girls there are very nice, and most are hot. Even if you arent very religious, great place to meet people. Go to church, its the best way to meet the oh so elusive "good girls".
Bigger campuses: play volleyball on campus if you see girls playing. All girls mess up, and when they do make fun of them. This goies for any sport you see girls playing on campus.
Once I went to run on a treadmill during a very busy period at the gym, two hot babes were in front of me waiting to use a machine. I say "How long have you been waiting for the machine?" and BAM I'm in (actualy good frends with one of the now). I've only done this once, because I prefer lifting to treadmills, but i often see HBs waiting for treadmills and elipticals.
DONT WHERE YOUR IPOD ARROUND CAMPUS, seriously I cant think of anything worse than being that antisocial, most peopleuse it as an excuse not to talk to you. Only where it to the gym.
When you first meet a girl, shake her and when she tells you her name, and when you must part. Every time after that, hug her. Do this with guys too except just shake their hands instead of hugging.
Have something you can do whenever you have nothing else to do. Guitar, shooting a basketball arround, jogging, anything except video games and TV and the internet(especially facebook).
This advice coming from someone with no social life in high school, and many friends and things to do i college.
