There is a term for all your effort: Afterschooling.

When parents say that their children are in a good school district it almost always means that the parents are doing a ton of afterschooling, private tutoring, or study clubs. The parents and kids do all the work outside of school and the school is quick to claim the credit.

Of course, if the kids aren't getting tons of afterschooling their standardized test scores show it and the school blames the parent.

Gee! Win win for the schools. Good standardized test scores: School takes credit. Bad standardized test scores. Blame the parent.

My middle son conducted AP study sessions for his classmates. Over the course of a semester, he had mastered the material much better than the teacher assigned to teach the class. The consequence is he was invited to teach the class many times. As usual, the person tasked with teaching learns the material best (not to be confused with the paid union hack warming a seat in the room).
