Any help?

i would say try to start a conversation either early or late in the day, the challange of course being starting the conversation, just go up and say hi. it will be hard. but all you really have to do is put up effort to get to know her.

I know that you might feel awkward but I say just go and say hi! In order to talk to her, you gotta get noticed first. You could try talking to her through common social media like facebook, but make sure you dont base conversation online only. When you see her, go say hi and just make small talk. Maybe if you're with friends, and things get weird, just introduce your friends to her in a casual way. Don't scare her away but making conversation, making effort and showing genuine interest is always nice. Try learning things about eachother. That way, you'll know for sure that you like her and not the person you thought she would be like. I'm sure things will work out once thetwo of you start talking. But yeah, just make the first move and introduce yourself. Offer help with academics, sports or anything :D PM me if you need more help. My ex was in the year above me so I know what you mean :)

well, before you start a conversation with her, you can probably make a soft smile when you see her, she will notice that for sure, that would raise her interest, then you can go with a "hi" while passing by (make sure not to awkwardly stay in front of her, unless she seems like if she wants to talk to you in that moment) in a thing of days you will be able to go to her and have small talks, maybe ask for her facebook, and soon you will probably have more chances of having long chats with her.
