Eye contact, conversation , what’s next is my dilemma?

I approached after 2 days of staring at each other today I gathered all my courage asked her for her notes (dumb ik, am cringing now) and she said ok and we spoke for a while, we go by same can to our respective hostel and in studying in same college. When I spoke with her her friend was also beside her and my van mates were there too yk (pretty embarrassing ik). Now what should I do after she gives me her notes what topic should I talk about then, this is not my area of expertise I want to know what’s next?
