If you want to bring your grades up I suggest studying on certain topics your struggling on. And move away from the topics your good at. For example if you are struggling in math, I suggest try to study how to divide or remembering your multiplication tables. You could also listen to some Lofi hip hop to relax while you try to study. And If your still struggling, ask a parent to help you! I know your mother/father would be glad to help too.
