<human>: I'm a 21 year old in my final year of university. Pretty much all year I've had my eye on a girl in one of my classes. Last week I finally had the balls and talk to her after class. We've spoken a couple of times since but they tend to be mostly small talk, and last only a minute or so as we both have to rush off to catch other classes. 

The problem I'm having is that I only have this class with her twice a week and don't see her other than that. I'm having a hard time trying to gauge her interest in me (if she has any). I don't know how to approach it from here on.

The fact that this semester is winding down and the thought that I may not have another class with her again (and thus not see her) really worries me. I've never felt this way about a girl before (which is pretty fucked in its own right seeing as we've only spoken twice), but I really can't get her off my mind.

I feel like I have a decent chance with her - I play hockey for the university, work out, get on well with other girls, etc., so it's not like I'm some total plug (hope that doesn't come across as arrogant).

The way I see it I can either just continue on with the small talk twice a week and see where it goes, or I can just come out of left-field and ask her out to lunch/a sporting event or something along those lines. Problem is, she's not particularly flirty or anything like that and I don't want to make it awkward or put her on the spot.

Apologies for the long post, and thanks for taking the time to help.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Really like a girl, don't get to see her often. Don't know how to judge her interest in me and what my next step should be.
