Pre-defense of master's thesis is a preliminary examination of master's thesis by the school, which aims to help graduate students find and solve the problems existing in the thesis and further improve the quality of the thesis. Under normal circumstances, graduate students need to participate in the pre-defense, and make amendments and improvements according to the opinions and suggestions put forward by the pre-defense Committee in order to successfully pass the final defense. If graduate students do not participate in the pre-defense, it may affect the quality of their papers and the passing rate of the final defense, but it will not be postponed.
