An important form of organized, prepared, planned and evaluated papers. In order to do a good job in the defense of graduation thesis, the school, the defense Committee and the respondent (the author who wrote the graduation thesis) should make full preparations before the defense meeting.

Students who participate in graduation thesis defense must meet certain conditions, namely:

1. must be fresh graduates who have completed all the courses prescribed by institutions of higher learning and previous students who meet the relevant regulations and have been approved by the school.
