Group A or B

If I’m doing Quebec / IB math for gr. 11 but then switched to Ontario curriculum for gr. 12 do I even submit my gr. 11 grades and like am I in group a or b 🤨 cuz like Québec math is like a billion times harder than Ontario (or at least the one I’m in 😟) but I’d be in group b so they’d consider that, but if I’m doing Ontario for gr. 12 wouldn’t I be in group a? Idk I’m so confused I need the lowdown cuz my gr. 11 marks are not great atm 😬
