Use the duplicate checking service provided by the school: most schools will provide free duplicate checking service for papers, and generally provide VIP, Wanfang and other duplicate checking systems. Students can check the specific operation methods and requirements in the school library or the academic affairs office.

Use independent duplicate checking systems: Some independent duplicate checking systems, such as HowNet and paperfree, can also provide duplicate checking services for papers. Students can check the duplicate by themselves through these systems, but they need to pay attention to choosing a formal platform to avoid revealing the contents of the paper.

Online paper duplicate checking websites: Some online paper duplicate checking websites, such as Turnitin and iThenticate, can also provide paper duplicate checking services. Students can upload papers to the system through these websites for duplicate checking.

Manual duplicate checking: Manual duplicate checking is a traditional way, which requires students to find duplicate content and mark it. This method needs more time and energy, but it can avoid possible mistakes when using the duplicate checking system.

No matter which way is adopted, students need to pay attention to the requirements of the school and the tutor and follow the specific steps to avoid unnecessary mistakes. At the same time, students also need to know the basic knowledge of paper duplicate checking, such as the principle of duplicate checking and the calculation method of duplicate checking rate, so as to carry out duplicate checking operation better.
