Help: If you don't know how to reduce the duplicate checking rate, you can ask your tutor or classmates for help. They may have some experience and suggestions, which will help to revise the paper better.
Regular inspection: During the revision of the paper, it is necessary to regularly check whether the duplicate checking rate has dropped. This helps to maintain confidence and continue to work towards the goal.
Pay attention to invalid labor: don't blindly modify the content, ensure that each modification has a clear direction, and avoid invalid labor.
Following these steps, you can try to check the copy again to make sure it meets the standards. If there are still problems, it is recommended to consult the school or tutor.
