OK so there's this girl in my class that I have liked for quite some time now. I've opened her and all that including number close. However now I figure I should take it to the next level and ask her out. But the problem is I have no idea on how to go about this, plus I was worried that on the chance she does turn me down that things would get real awkward seeing as she sits right behind me. So I guess the question is how should I go about doing this? And is there a way to ask her out that might increase my chances with her. As far as I know she doesn't hate me and she does send out IOI's to me. Also what time should I do it before, after or during class. I'd appreciate it if someone could give me some insight on this matter thanks.

talk to her more before you advance. see if she got a bf, get to know her then from there go i for a date
