Before students submit their papers, the school will double-check the papers to ensure their originality and rigor. However, some students have questions: will the paper be checked again after it has been checked? In fact, there is no definite answer, because the regulations of each school are not exactly the same. In some schools, if the paper passes the initial investigation and no problems are found, it will not be re-examined. But in other schools, every paper will be rechecked to prevent it from being missed.

In addition, we need to know the application of duplicate checking system in graduation thesis. The duplicate checking system was originally designed to prevent students from plagiarism, but with the development of technology, it has been widely used to judge the quality of students' graduation thesis to ensure the accuracy and authority of graduation thesis. Graduation thesis duplicate checking system can detect irregular quotation, plagiarism and other behaviors in the thesis, and put forward evaluation and improvement suggestions on the quality of graduation thesis. Therefore, in graduation thesis, we should develop good academic habits. When writing a paper, we should pay attention to clearly citing the paper, rationally using the literature, standardizing academic terms, and reviewing the manuscript as fully as possible before finalizing the paper to ensure that the responsibility is public. Avoid repeated inspection or missing inspection.
