If you're a Freshman/Sophomore, it might be hard. For me, I noticed girls dated guys older Junior year+, usually grad students, or recent graduates. First few days of Freshman year are easy because some girls become sluts. I think 3-weeks, the girls with high school boyfriends finally break up and they're fair game. Then you repeat with Freshmen girls)
Junior year onward, it was a joke. Sooo easy to game girls. Senior year? Forget it. Almost effortless, all years are pretty much open.
Personally, I think gaming in college is easier than gaming out of college. I'm 23, I graduated 1.5 years ago - I have almost no confidence opening girls out of college because they prolly make more money than me (

) and are probably dating 30+ year old dudes. This is why I avoid girls my age and stick to the 18-20 year old college girl range.
Scheduling a date after a cold opener easy. I meet the girl at parties, (or now online), so I meet them in person in a neutral location - or bring them out with my friends (not inviting their friends - fuck that).
