How do i get a boyfriend in my world civ (pre-ap) cl?

see i like a couple guys in my cl, except that i really want to do well in this cl and its a really hard one. whenever we're in a group together to work on something, the teachers dont give us a lot of time and i want to get it and done and get an A, but i dont want my crushes to think im this goody-two-sheos who cant have fun and only wants to work. how do i keep an a or b in this cl but get closer to these guys and show them how fun i am in the cl (not out of school)?
