As a gymnast, I can tell you how hard it is when you go straight from school to practice and not get home from practice until 10 PM with a stack of homework in front of you and having to finish it and not getting to eat dinner until midnight
Unless gymnastics is going to get you into college, I'd suggest focusing on school. Not trying to be a dick, I've just seen my cousin, for example, be pushed into baseball his whole life because my aunt thought he'd make it big and be rich or whatever. He now can't hold a job, and his last one was a bagger at a PW, which his mom got him because she also worked there.
I agree with mgoveia. Continue with gymnastics as your hobby or passion but dont let that take priority over your studies. Unless we are wrong then our bad.
My sister is a gymnast for Utah State (she used to be with Oregon State), and she went through the same thing. And she graduated with a 4.0.
You can do it.
