If there is no appeal for the second-instance master's thesis, there will generally be no big problem. Usually, students will pass two rounds of exams before defending their thesis. If the test paper has passed the exam in both rounds, the quality of the test paper should be unlikely to affect the final evaluation result. However, the specific situation still depends on the regulations of various schools and colleges. Some colleges will ask students to complain, otherwise it will affect the subsequent degree granting and other issues. If there are similar disputes, it is recommended to know the relevant regulations in time and make rights protection complaints within the prescribed scope.
