I wanna impress my parents for doing better in school!?

Ok so I stayed back 2 times. as of right now I'm a freshman that's sup post to be a junior. So I'm two years older than everyone in my grade. It's extremely hard not to pay attention because everyone is very immature. I've been thinking about adult ed instead of continuing to go to the school I'm at now. Is there any other options I can do possibly or is Adult ed good?
