girl i like is 4 years older then me

I want to say no, but... how much longer do you have till you're 18? Get to know her and be friends for right now? Can you do that for another year or so?

I seriously doubt anyone would prosecute a girl for getting with a guy barely under 18 if she's within a few years. They only rarely do that in the opposite gender situations. So I would say get to know her and go from there.

Do you think shes even interested? Give us more to work with here. I dont like pulling teeth to GIVE advice.

This sounds more like an attraction rather than actually liking her especially since you just met her. I'd at least try to get to know her before jumping to a conclusion like that because for all you know she and you could be complete polar opposites. Also, age in this situation shouldn't really deter you. The person I'm currently in a relationship with is 5 years older and it honestly doesn't feel like there is that age gap.

Hopeless. You just met her. Talk to her. Dont jump into it, as toe said, you dont even know her, so unless youre looking for a hookup, just talk for now.

Don't. If she rejects you, how awkward do you think it will be to keep attending classes with her? Girls at her age rarely date down. Unless you got some serious game, it seems like a waste of time to try and get her interested.
