Different undergraduate colleges have completely different requirements for duplicate checking rate of engineering papers. Most universities require the duplicate checking rate of undergraduate engineering papers to be 25%, while some universities require it to be less than 20%.

In order to ensure that undergraduate engineering papers can successfully pass the duplicate checking test, students are advised to reduce the duplicate checking rate as much as possible, do a good job of citation and annotation, and avoid plagiarism and over-citation. At the same time, the specific requirements of the duplicate checking rate need to be subject to the relevant regulations of the school.
