TITLE: Me [20 M] has a problem with small talk, but I am trying to get a sorority girl interested in me.
POST: I have had several classes with this girl at college. We have never sat near eachother, but we have worked in groups. I never said anything except for questions about the classes that we had together. I don't want it to be like I am talking to her because we have the same major.

Other than class or college related stuff, I have no idea who she is. I have asked some of her sisters about her and they say she is awkward. I sent her an email after letting her know that I knew her name in person. I asked her about going to a movie that was playing on campus. I am off campus, but I wanted to go. She kindly wrote back that she was back home.

I saw her in class, and went back to where she was to explain myself from the weekend. It was an awkward conversation because she snapped a picture right before I sat down. I didn't even ask to sit there, I just had my mond on the weekend. I could not tell if the conversation was awkward because of her or me. 

I then wrote her on email after talking with a friend from class who suggested it. This time I explained why I wanted to know who she was and how we have had a few classes together, and I have no idea who she is even at the end of the semester. It bothers me. 

How do I move forward before the end of the semester(which is probably adding to the pressure)?
TL;DR: 
Needing advice on a girl who mostly talks just to her sorority sisters, they all sit together. Outside of class she is still in a group. I have made a few steps, how do I move forward?
