Thesis defense is a formal form of thesis evaluation, which is carried out after graduation design is completed. The school will do a good job in organizing the defense in advance, including selecting students who can participate in the defense, organizing the defense Committee, arranging the venue, and passing the standards through consultation. Respondents should be fully prepared in advance. On the day of defense, the school teachers and their defense committees will review the graduates' papers and ask questions on the spot. Graduates need to prove the correctness of their views at a high level and get unanimous approval from teachers.
