There is no uniform standard for paper duplicate checking and defense order, so the order of paper review in major universities is arranged by the schools themselves, and everyone should follow the specific regulations of their own schools.
Some schools require a group of people to defend their graduation thesis first, and then only those who meet the requirements of duplicate checking can defend their thesis. There are also some schools that require all graduates to defend their graduation thesis after the tutor confirms that there is no problem with it, and then the school uploads the defended thesis to the duplicate checking system for repetition rate detection.
