Under normal circumstances, the qualification standard of the duplicate checking rate of undergraduate graduation thesis is usually stipulated by the school, and the duplicate checking rate is generally required to be below 30%, but the specific requirements may vary according to different schools and majors.

In general, the duplicate checking rate of undergraduate graduation thesis is below 30%, and the thesis is considered qualified and can participate in the graduation thesis defense. If the duplicate checking rate is below 15%, you can apply for evaluation of excellent papers at the college level. If the duplicate checking rate is below 10%, you can apply for the evaluation of excellent papers at the school level.

Therefore, graduates should pay attention to paper writing and duplicate checking. HowNet and VIP are systems used by most schools, and their databases are authoritative. Papertime and paperfree are auxiliary revision references, which provide free weight checking, machine weight reduction, online revision and other functions, covering about 70% of HowNet's data, which can reduce the absolute cost of pre-test fees. To be on the safe side, it is recommended to use the duplicate checking system required by the school or institution for testing.
