I think you can simply explain your evaluation of your child's exam (whether it is good or not, whether it meets your requirements, etc.) ), and you can also put forward your own suggestions for the exam. If your child gets good grades, you can be sure of the teacher's teaching. If the child's grades are not good, you can ask the teacher to help you coach the child, pay more attention to the child, and so on. And express gratitude to the teacher. Finally, sign your name and write the time, that's all.
