Parents also need to send text messages.

Hello, the child did badly in the exam. Parents need to know the teacher's specific reasons, their children's performance in school, classroom performance and other issues, which need parents to communicate and understand. For weaker subjects, children can be enrolled in cram schools to help them improve their grades.

I suggest that you can make a plan for your child's further education in advance. There are many further education programs that can help your child enter the ideal school. If you help your children make plans early, you will have more choices at school.
