Unless you plan on sticking around with these girls for the long run, it doesnt matter. You will be with your classmates pretty much everyday/allday for the next 2 years. This could potentially make your life a living hell.
My suggestion for you is to find the hottest girls at the local colleges. Study at those libraries, use the "medical school" angle, get the girl, then when you dont have time for her (because of school) you can avoid seeing her ever again....just dont study at that library again.
