Generally, the pass rate of external examination of master's thesis is between 80% and 90%, because the graduation thesis of graduate students is completed under the guidance of tutors. Graduate students must have made some progress in scientific research during their thesis writing, thus completing their graduation thesis.

It's not difficult to say, after all, most people can live. But it is not difficult to say that a batch of papers will definitely fail. No matter how the thesis is written, it is impossible to be 100% sure, which is actually the key feature of blindly reviewing the master's theory.

External trial is both metaphysical and normative. Metaphysics means that no matter what, you can't be sure. Sometimes the reason is metaphysical. Normalization means that blind evaluation is very concerned about the overall structural logic of the paper, which is very important.

The reasons why the master's thesis failed the external examination;

1, the paper lacks originality, and the experimental arguments in the author's article are copied from others, or it can be simply seen that they are inferred from known papers and documents.

2. The analysis is not in place. Although the external audit has made new discoveries, the paper has not refined the key points and failed to reach the theoretical height. There is only a simple qualitative description, lacking qualitative and theoretical analysis.

3. The content of the paper is not enough, that is to say, the quality of the paper is not high, which does not conform to its purpose and field of running a journal.

4. The argument is not sufficient, the argument put forward in this paper can not be confirmed by the experimental scheme, or the logical reasoning is doubtful, and the experimental methodology theory is unreliable.
