I need some help with this girl?

since you have same cl with her you should try to sit next to her everyday. then you have the chance to ask her about the cl/hw/ and as the convo gets longer talk about your major and ask her what her's is. as you guys get to know more about each other ask her to come study with you. if your're shy studying alone with you two then invite a couple of friends to come study with you. hope that helps
