Showing Him I'm Interested

Hey ladies! I'm a university student and this year I met a cute guy that happens to be in a few lectures and labs with me. We usually sit together as we are both new to the uni. I am an outgoing/funny person but I don't have a lot of experience with relationships and flirting and such so I'm not sure how to maybe change the tune from friendly to more than friends? Like I said we sit together in class, laugh a lot and eat lunches together sometimes so I think it has potential to go in that direction (I'm almost positive he's single). Could you all maybe give me some tips? Is there a way to drop hints or something too? Thanks so much 😊
