The question you are talking about is this. According to the relevant regulations of education, students are not allowed to repeat grades, even if their academic performance is poor, they should be upgraded. Because quality education is being implemented now. Students can't be measured only by their exam results. At present, most schools have established students' status at the beginning of their children's schooling, which continues until junior high school. Junior high school students can't take the exam without a student status. Your child's student status was replaced by the teacher's child. What about the student status of the teacher's child? Did the school miss it? You find the school and communicate with the school leaders. Give your child an upgrade and make up your student status, and you will get what you want, without saying anything. If the school insists on demoting the child again and again, you can go to the Education Bureau to solve it.
