College game is my specialty, used to teach the stuff a few years ago, but another player on this forum posted a great question that seems to fit your needs well here:
best-way-to-approach-a-girl-in-a-lectur ... 55968.html
The steps to a pick-up are:
1. Approach
2. False Time constraint
3. Opener
4. Continue conversation. DHV, establish kino, and neg whenever possible
5. Hook
6. False leave (so you actually try to leave the set, if you've hooked them they'll pull you back)
7. Pump buying temperature (meaning you continue building attraction by negging the target, but you do want to shift focus at this point and focus on the target, while building rapport with the obstacles)
8. Isolate to seduction location
9. Continue building attraction, escalating kino, etc.
10. Close.
From here there are a lot of directions the pick-up can take. Will she leave with you? Can you get an insta date? Are the logistics simply not there and you need to number close and leave?
There are rules on how to handle each situation, but i think this is enough to get you started.
Day game isn't as different from night game as some people make it out to be, though there are some key differences. For one, women go out at night to meet guys, but at the same time they will have a bitch shield up to quickly shut out guys they aren't interested in. Day game this shield isn't really there, but at the same time women aren't out to meet guys, so the rules are a bit different. Day game almost always should end with a #-close, though sometimes a k-close is possible. Logistics just aren't in your favor, so you #-close and set up a day 2 and make the logistics go in your favor.
The key to picking up a lot of college girls is to have a strong social circle. You ultimately want to meet other women through your friends, and that way you already have a lot of good social value. the ebook Conquer your campus is a great starting point, and I would also suggest Braddock's seminar video on youtube. He's pretty much considered the authority, and while I disagree with some of his ideas, what he teaches is solid and it works so check it out.
