1. blind evaluation: it is a system that organizes expert group evaluation, that is, anonymous submission, which means that the evaluation tutor does not know who the author of the paper is. If you send a dissertation without the author's name to an impossible expert, the score should be the most objective.
External audit: refers to sending papers to experts from other units for audit. Some schools are managed by the degree office in a unified way, while others are guided by tutors. 90% of the experts appointed by the tutor submit papers for review, and they can only pass because of the good relationship between the experts and the tutor.
If you want to get a degree certificate, you must be qualified to participate in the thesis defense, which requires that our in-service master's thesis must pass the exam. Many students have heard of double auditing, but they don't know which two auditing methods are involved. In fact, one is blind audit and the other is external audit. Then someone will ask whether the on-the-job master's thesis needs double review or only one of them can be reviewed.
