TITLE: Me [17 M] with my Female Friend [17 F] Who I Met in University is ONLY Interested in Talking About School
POST: So I'm a freshman and during my first week at University I met a girl whom I have a couple of classes with and I like her. Like like her. Only problem is: when I asked for her number she assumed I was asking so that we could discuss school/assignments together. When I talk to her in class it's all fine, and we'll tell each other funny stories/talk about normal things but I tried texting her the other day and she

1. Didn't respond until 24 hours later and 
2. When she did, it was regarding an assignment question. 

It was pretty much as if she had never received the text from me. I'm sensing mixed feelings here; I don't know if she's just afraid about texting and so she simply decides to talk about school related stuff or is she just not interested at all and ONLY wants to talk about school related stuff? How can I get her to want to talk about other stuff?
TL;DR: 
I met a girl at the university we both started going to and I'm finding myself liking her but she ONLY ever wants to talk about school. How do I get her to want to talk about other stuff?
