Sounds like you are aware of the options. You can get a GED or try to get into college early. You can homeschool or maybe find a school like the Sudbury Valley model. You can keep attending school and try to push the boundaries of what you can get away with or otherwise game the system.

But you can't make your school not-school. It's always going to be boring, mostly pointless, mostly a waste of time. Accept this and deal with it.

Or you can stay frustrated and angry about it instead. This is totally normal, expected, and acceptable teenager behavior--it worked fine for me--but it won't actually change anything.

Good luck.
