I have feelings for this girl in class, we don't talk much. Should I confess straight away maybe she might feel relaxed?

I know this girl at college who I like. She's born again Christian. She's shy. She feels nervous when I sit close to her. And she doesn't have much to say to me. We share some classes with her. But I am not in her class all the time. I want her as a girlfriend, what do I do? We both have busy schedules to talk outside class.
