Generally speaking, the score given by the university teacher who stays up late may be a certain aspect of you, which makes the university teacher feel that he doesn't like you, or that you don't attend classes often and are suspected of being late or absent from class, so he gives you a very low score. If it is malicious, you can find the party Committee or principal of the school with relevant evidence, or some schools, and some disciplinary committees report it to the local departments of these schools.
