Girls do you think she likes me?

This gets asked a lot, but thanks for your help. So I like this girl and she is in one of my classes, but I dont get to sit near her at all, so I don't get to talk to her. Only at the end I get to but for two minutes. So one day I said something nice to her, I dont remember what, but it was good enough for her to say awwww and smile. And another day we got to work in groups and i was in her group and when we had to go back to our normal seats, she said i'll miss you. I try to not think this means anything, but since I do like her I'm hopefull, so thats why im asking this. Or what can I do to help me find out if she likes me? Like subliminal things, thanks.
