Different schools have different duplicate checking systems, and the duplicate checking results will be different. The normal requirement is that the duplicate checking rate should be between 5% and 10%. Generally speaking, the requirements for duplicate checking rate of master's thesis are as follows:

1. If the repetition rate of master's thesis does not exceed 5%, you can submit your defense directly.

2. If the repetition rate of master's thesis is between 5% and 20%, it needs to be reviewed by the tutor. It is also necessary to determine the originality of the thesis, judge whether there are academic misconduct such as plagiarism in the graduation thesis, and then finally deal with it according to the results given by the tutor.

3. If the repetition rate of the master's thesis is between 20% and 35%, you need to fill in the examination and approval form for paper duplicate checking, apply for revision of the thesis, and check the duplicate before replying.

4. If the repetition rate of master's thesis is above 35%, it is necessary to postpone the defense. The author of the paper must carefully revise the paper, and after being reviewed by the tutor, fill in the application form for duplicate checking of the paper six months later. The revised paper can be defended by duplicate checking.
