This is what I'd do
Firstly and foremostly, I'd work really really hard, either way, you're going to get out what you put in. Put in hard work and improve.
Secondly, maybe talk to a teacher about it perhaps, be honest and ask them how you will be able to get the best out of a career in art.
Thirdly, perhaps say to your parents its incredibly better back at you're old school. Surely they want you to get the best out of your education.
When I think up some more advice, I'll come back to you.
Good Luck.
