20% duplicate checking means that after your paper is submitted to the duplicate checking system for testing, the repetition rate is 20%. If the repetition rate required by your school is less than 30%, then your paper duplicate checking rate has reached the standard. You can check whether there are typos or grammatical errors in the paper later, and everyone needs to pay attention.
Paper duplication checking is a very serious matter, and everyone needs to take it seriously. If you haven't checked the copy yet, you can use the paperless first draft detection system to check the copy of the paper.
