Students who pass the examination of graduation thesis must ensure that the repetition rate of their thesis is lower than the standard set by the school before they can be qualified. However, many schools have different requirements for the repetition rate of papers. Some schools require that the examination rate of papers is low and they must be qualified within 20%. If the repetition rate of the paper is above 20%, it needs to be revised and reduced after being signed by the tutor. If the repetition rate of graduate thesis is less than 15%, it is considered as qualified and can be directly applied for defense.
