Can't you take the tests ahead of time if you ask? Even if not, driven by curiosity you'll find math and science tests in school pretty easy if you've bothered to read ahead.
No
I moved ahead by studying computer science at the university when I was 13 years old. Thereby I was taking courses at school and university in parallel. But the school courses were all at regular paces. Then I had to repeat topics at school that I learned years ago at the university. I had almost finished my bachelor degree before I had finished high school. The school was a complete waste of time. I also got demoted by one or two grades in school for "not asking enough questions in classes"
Eventually this cultinated in a row between my parents, the tracher and the headmaster.
Because mu parents had my back, she stopped creating dramad but I never got the grades i was meant to.
