Is 7th grade more important than 8th grade?

It depends. If you are in 7th grade Advanced Classes, than 7th grade should be your life. If you are in 8th Academic than it isn't as important. But you should still try to pass your classes!

It depends. But for me being a former 8th grader, now a 10 grader, I can say that 8th grade can be more important because it prepares you more of what high school would look and feel like
