Is it anyway possible to volunteer at a high school but you're still not graduated? or a drop out?

I am a drop out, but for reasons I cannot go back. I am planning to get a GED, and all, but my question is, I want to volunteer as a fileing person, a library's istant, ESL istant, or someone who can do ANYTHING around the school. ANYTHING. How can I apply? Who do I talk to? Will they accept me even if I didnt graduate? I think I can help with my language abilities cause I can speak both Korean and Japanese fluently. and maybe I can help ESL students. But that's JUST an idea. I just want to be in the school to volunteer. Help???? I'm still 17 btw. Aand please stop telling me to "go back to schoool" cause i heard it enough, and i already said i cant go back. i REALLY cant go back. im not kick out or anything.
