Was she attracted to me?

Alright there is this really pretty girl in my discussion group in college. Well we got a test back a week and a half ago and I did good and most of the cl didn't so I was comparing mine with 3 students. She comes up to me and starts looking at my paper and her eyes get big. So she starts saying that we should get together to turor. She looking me in me eyes and I think she can sense my shyness or whatever. I am not really good with girls so I sort of put up this wall to protect my emotions. I appear standoffish and unfriendly its my own defensive mechanism. She seems really interested in tutoring but I am like a dull ok. Cl and discusion are cancelled for alwhile and I don't see her again until 3 days ago. Well I see her and we make sort of prolonged eye contact but we don't say anything. Today she was sitting in front of me at lecture and she turns around and see's me and she gives me a slight smile then looks away quick. I don't smile back and I have kind of a mad looks on my face. Well today she comes in talking to another guy and we make prolonged eye contact with each other but say nothing. Today in lecture I sit behind her and she starts acting different, she keeps on turning her head in my direction without looking at me. She keeps figeting around and doing something weird with the cell phone. Does she like me? I really like her but I don't know what to say
