How to send a text message to the teacher if the child doesn't do well in the exam.

First, I expressed my concern for the children's grades, then I thanked the teachers for their hard work, and finally I offered to cooperate with the teachers. When children do not do well in the exam, they should first express their concern for their grades, then express their gratitude to the teacher for his hard work, and finally put forward their willingness to cooperate with the teacher. Hello, teacher, I'm XXX's parents. Recently, I learned that my child's exam results were not satisfactory, and I was a little worried. I know that you have been educating your children with great care, and we are very grateful. I want to talk with you about what children need to strengthen, and how we, as parents, should cooperate with the work of the school to help children improve their grades. Looking forward to your reply, thank you.
