i'm a sophomore in college also. i went to three frats last night to practice my game (i am a beginner). i felt a little weird about using the classic openers but i tried just coming up with my own on the spot or if worse came to worse, i would just introduce myself. it started me off bad but it was cool because i would use negs and play the game and i actually got two numbers from fairly good looking girls. i was surprised because this was aggressive for me and i'm usually a more reserved guy.
my advice would be to come up with some openers and practice them (i need to do the same

) but once you have them just stick to the program.
also if you are a beginner like me, try to go for phone numbers for now to work on your opening and mid game. i noticed on the show how this is what they focused on the first few weeks so i didnt want to go straight for sex with a girl the first time trying. just start out slow and aim for phone numbers. from there you can advance. good luck at those parties out there buddy
