Easy. Go onto the campus in college student fatigues:
-worn blue jeans
-sneakers
-innocuous t-shirt or button-up
-and MOST IMPORTANTLY a backpack or bookbag. Nothing looks more suspicious on a college campus than a guy who's not carrying something.
Walk around campus and do cold approaches. What's important to keep in mind is that you need to have the right body language.
-Open stances
-Slow Swagger
-The correct type of smile

Examples of good college openers:
(I start each of these with the word "hey" to remind you to get your target's attention first)
-"Hey, what do you think would be the best conversation starter? And be honest!"
(this is witty/charming and not too aggressive, if you have the time to game chicks)
-"Hey, I'm just headed to class and I only have like 1 minute, but I saw you sitting here and had to come tell you, you are incredibly cute"
(this is way more direct, but it shows your intentions and your confidence.)
-"Hey, I like your style. I bet you do something creative"
to which she'll respond "yes" or "no"
at which point you can either neg her or just open the set.
