The requirements for duplicate checking vary from school to school. Generally, the requirements for undergraduate courses are within 30%, and those for graduate students are within 10%. I am a graduate student, and the requirements of the school are within 10%, and the duplicate checking system is cnki. Let me share my experience in revising my thesis:

The first stage: the paper has just been written, and I can't wait to go to paperpass official website to search (3K words can be free after mobile phone verification), 10 yuan/10,000 words, and I found 30%. Other students checked on Taobao papertest, and the results were similar (there was a feeling of being pitted by paperpass), and the abstracts were all red. Then, modify it word for word. Check with papertest after modification. The repetition rate is still very high, 265,438+0%. Continue to revise, and carry out word-by-word scrutiny according to the revision suggestions of papertest. Reorganize the language where there is a large area of red.

The second stage: If you think there is no problem, just use Taobao's HowNet to check. This is very expensive. You need 160 yuan. In order to graduate smoothly, we can only bear the pain. The result is 4%, and the result is not bad. Then it was simply modified, and some duplicates were deleted. The final check was 1.5%.
