The blind trial will be sent to the Ministry of Education and reviewed by teachers from other schools (perhaps a review team composed of teachers from several different schools), which will definitely be stricter.
Some schools may have a good relationship with the submitting schools, and the passing rate will be higher. If you write well, you don't have to worry about these problems. Even if the relationship is not good, the teacher will not be embarrassed to write well. Bad writing depends on luck.
Blind trial adopts one-vote veto system. As long as one vote fails, the paper will fail.
Blind evaluation is a Chinese character, and its pinyin is máng shěn, which refers to a system of organizing expert group evaluation, that is, submitting evaluation anonymously, which means that the evaluation tutor does not know who the author of the paper is. In this way, the false positive rate of scores is low, which is generally used in college marking. The blind evaluation system is to send dissertations without the author's name to unknown experts.
External auditing refers to sending papers to experts from other units for auditing. Some schools are managed by the degree office in a unified way, while others are guided by tutors. 90% of the papers are submitted by experts appointed by the tutor.
The right of reply can only be obtained after the blind trial and the external trial are passed. If you fail the defense, you can't graduate. As long as two experts pass the blind trial or two experts pass the external trial, they have the right of reply. The defense Committee does not include experts from external auditors, and only half of them can graduate.
