The time for blind evaluation of grades varies from school to school, and it usually takes about 25-50 days to produce grades one after another. Blind trial is anonymous submission. In the process of review, the review tutor can't know who the author of the paper is. This is a common method used by colleges and universities to review papers, so that the scores reviewed are the most impressive and the fraud rate is very low.
The blind examination of general master's thesis begins at the end of March of the graduation year. The master asked to upload his thesis to the designated website, and then the external audit began in April. Basically, the results will be available in May after one month. If you pass, there is no problem. If you don't pass, inform the students.
