How do I get him to notice me?

I agree with the rest of them, go up to him and say hi. Before you know it the semester will be over and he'll be gone forever unless your lucky enough to see him again.

In other words don't sit around and wait for something to magically happen, do something about it or else he's gone for good.

You gotta do more than say hi the second time you see him though because back in highschool girls would always come to me and say "hi (my name)". I just thought they were being friendly around me and never though they liked me but now after coming to this site I realized how blunt I was when noticing girls.

You gotta start a real conversation with him otherwise you're just gonna be some girl that said hi to him and not someone he'll notice, unless you say "hi (his name)" really slow and smooth and give him a nice smile.

Walk up to him and say " Hi, name Jane. Nature will take it's course from there.

Go up and talk to him. Say the two letter word!
"Hi!"
