Welcome to the forum.
I am sure you will get some really good advice.
The first thing that you should do is at least have a conversation with her. Is there some way you can start a light conversation with her. If you know what any of her interests are you could ask about that. What class are you in together? Mabe you could ask her a question about an assignment or when a test is. You could probably get an idea of her feelings by the way she answers. Kinda think about a follow up questions in case she shows some interest.
If she wears perfume you could ask her what she wears because you really like it.
Obvisouly you have to talk to her to ask her out, so that should be your first step.
Good luck - be brave
