What happens if I fail a quarter (which is almost all my classes) of school do I have to retake the quarter or do I get held back (middle school) I need help fastt in Colorado

I dont live in Colorado but if I were you and I was concerned about failing or getting held back I would ask the school or your parents, where I live if we fail we have to redue it with the permission of our parents or summer school your forced to go just depends.
