I think you can find a responsible institution and a professional teacher to communicate with your children in thought and study, so that you can understand their current situation. My child used to be like this. Anyway, he refused to take remedial classes, but later the teacher talked to him and he accepted the remedial classes. Maybe this method of parenting is wrong, so I enrolled him in Le Shang education and his grades improved. I think it's ok there. You can.
