Communicate with teachers: If you think you have got an unfair score, you should communicate with teachers first to understand their grading standards and the shortcomings of your score. Sometimes teachers may have misunderstandings or the grading standards are not clear enough, which can be better understood and solved through communication.
Ask for help: If you feel that your grades are really unfair, you can ask other teachers or academic consultants for help. They may provide some useful suggestions and support to help you improve your grades.
Complaint: If you think your grades are completely unfair, you can complain to the academic affairs office of the school. When appealing, you need to provide evidence to support your claim, such as examination papers and homework.
No matter which method you take, you should keep calm and rational, and don't express your views emotionally or excessively. Communication and consultation with teachers or schools may take time and patience, but if you firmly believe that your grades are unfair, don't give up seeking solutions.
