1. Avoid competitive pressure: Open scores may lead to increased competitive pressure among students, which may lead to a series of problems such as comparison psychology and anxiety, which will adversely affect students' physical and mental health. Non-public grades can reduce the competitive pressure among students and make them pay more attention to the learning process and the improvement of comprehensive quality.

2. Pay attention to the comprehensive quality evaluation: Not disclosing scores can pay more attention to the evaluation of students' comprehensive quality, not just the level of scores. Through comprehensive quality evaluation, we can get a more comprehensive understanding of students' situation.
