After the paper is finished, it needs to be checked again. Whether it is a university graduation thesis or a periodical thesis with a professional title, as long as the repeatability of the thesis is within the prescribed scope, it can pass the preliminary examination.

Generally speaking, the bottom line of the qualified range of paper repetition rate in most schools is 30%, and the general qualified range of undergraduate graduation thesis is about 30%. If it is a master's thesis, the repetition rate should be less than 10%, and the duplicate check of excellent graduation thesis should not exceed 15%. The repetition rate of doctoral dissertations is generally less than 5%. There is no uniform standard for the qualified range of graduation thesis duplicate checking rate, and different schools and different education stages will have different requirements.

The higher the educational level, the higher the standard of paper duplicate checking rate. Taking core journals as an example, the duplicate checking rate of papers in core journals is as high as 10%- 15%, and the requirements of general journals are usually the same as graduation papers.
