OK an update: I found out from her friend that she knows I like her, and things seemed positive, but after that she kindof stopped paying attention to me for a few days, part of which was that night we hung out. My best friend tells me that she sends mixed signals, so I just assumed that she wasnt interested. But today I'm walking to class, and she joins the hallway traffic right next to me. I say hi and we immediatly get into a conversation as I walked her to our class. On the way up the stairs she starts pretending that the climbs too much for her and braces her self on my shoulder. Then in class, coincidentally we had a sub again . I sat in my assigned seat, once again not noticing the sub. She and her girlfriends formed a little group to do their assignment. Then while I'm doing my work by myself, I've learned not to pay TOO much attention to a girl, she calls to me from 3 rows over "Hey *** your smart, come and work with us" seemingly innocent except she went ahead and did her own work anyway. So I'm thinking about asking her to a REAL date, but I think I should ask one of her friends just in case I am getting a mixed signal.
