Translate percentages to letter grades. I know this from personal experience.
You have to sign up and answer questions to get points and when you get points you can ask questions. Then other people would answer your question for points as well
F(x) = x²-x
g(x) =1/x
1) h(x) =f(x) -g(x) = (x²-x) - (1/x) = (x³-x²)/x (x≠0) =>
2)h(x) =f(x).g(x) = (x²-x).(1/x) =x(x²-1)
3)h(x) = f(g(x)) = (1/x)²-(1/x)
My opinion is that it’s not too late because if you don’t have the time now you might have it next year plus it would help a lot with college and possibly make it easier. but it also depends how much time you want to spend doing school instead of having fun because i understand if your not enthusiastic about school but still want to do better at it.
hope this helps :) whatever choice you make is a good one
