Each school has different requirements for duplicate checking rate. Some schools have stricter requirements, while others have looser requirements. When you check your own papers, you must first find out what the duplicate checking rate of your school's papers is.

Generally speaking, a loose school paper is qualified as long as the duplicate checking rate does not exceed 30%, so it is a normal paper, but the duplicate checking rate of some strict school papers is generally 10%- 15%.

In some schools with relaxed requirements, those with duplicate checking rate below 20% can apply for excellent papers at the school level, and those with 10%- 15% can apply for excellent papers at the school level, but those with strict requirements cannot.

The higher the degree of paper duplicate checking, the stricter the requirements, such as:

If the repetition rate of undergraduate thesis is less than 30%, you can apply for defense; < 15% can apply for excellent papers; < 10% can apply for excellent papers at the school level; > 25% have the opportunity to revise it within 5 days, and the revised test failed to pass the extension defense.

If the repetition rate of master's thesis is less than 20%, you can directly apply for defense; If the repetition rate is less than 40%, there will be an opportunity for revision within 2 days. If the test fails after revision, the defense must be postponed; If the repetition rate exceeds 40%, it can only be directly extended for half a year.

If the repetition rate of doctoral thesis is less than 10%, you can apply for defense; > 20% directly extended for six months to one year.
