Is the art class girl interested in me?

Recently I met this girl in art class. Her name is Bella, and she's Italian, and head of a sorority. I'm not a frat guy, but I'm definitely like a grungy, bad-boy to a degree. We met in art when she left her cell phone behind and I grabbed it in order to talk to her. She asks about me and like tries to learn. She asked if I wanted to go to a museum with her, or to play tennis, but girls advances are so opaque. Dhe is somewhat interested I can tell, but I don't know how to come at this one. Any suggestions?

it seems like she likes you and she really wants to get to know you. you should definatelly go for it

It seems like she's interested, but you can never be sure. Do you want to go, or go out with her? If yes, then go. What have you got to loose? I think go to the zoo and then play tennis too.

Sounds like she is interested to me. If she wasn't she wouldn't be asking you to do things. Believe me, if a girl is not interested she won't want to do anything with you.
