1, if the student's thesis itself is qualified, it will be unbalanced because of the index problem.
2. If a student belongs to an irritable group, or the paper grade is very important to him, then he is also very angry.
In short, as a student, if my thesis is really not bad, I still hope the teacher will show me mercy. If I can devote myself to my undergraduate thesis, there is no big problem, and I think I should give it. After all, the score of the paper is very important, but the second debate can make up the exam, but if you get stuck for no reason, the students will be really angry.
