There are many approaches to raising children. You can be supportive of your child by giving them confidence, teaching them to learn from their mistakes or allowing them the independence to make their own decisions. I fail to see how not knowing some details of your child’s class schedule is an issue as long as you child is achieving.
I remember stressing out if my D got into accelerated math in 6th grade or how many AP classes she chose to take in HS. She is about to start college and I am not certain if these were the things to have worried about. She may have leaned more from her after-school and summer jobs and from the decision to stop playing a sport she once enjoyed than from any class in school.
