The duplicate checking system only detects the repetitive parts of the paper, and does not judge the overall structure, format and grammar of the paper. After duplicate checking, the contents of the paper can still be added, deleted, replaced and reorganized. For the detected duplicate parts, students can also use papertime machine to reduce weight and assist in revision. Common modification methods include changing sentence structure, replacing words with synonyms, and reorganizing paragraphs.

These changes must be based on reasonable logical principles, and meaningless or illogical changes cannot be made in order to reduce the repetition rate. Students need to know the feedback after duplicate checking and communicate with the instructor or relevant departments in time to ensure the quality of the paper and successfully pass the duplicate checking test of the school.
