About 30%.
There are those who do not graduate with doctorates and masters, and generally do not have academic qualifications or degrees. Some graduates have academic qualifications without degrees, while others have both academic qualifications and degrees. The proportion of blind review of master's thesis in different schools is different, generally between 30% and 50%. After passing the doctoral plagiarism check, I helped the teacher write the patent and gave it to him, thinking that I could go out to play and prepare, but today it really turned out that I was selected for a blind trial, and there was a 9% chance that I would be selected. I'm really worried now that I'm going to delay my graduation.
There is a 20% probability that you will be selected by lottery and submit your best answer on the weekend: The blind review will definitely be stricter than the general review. The crux of the matter is that the general review is done by teachers from your own school. Because it is your own school and the tutors are familiar with each other, it may be easier.
