No explanation. Because after the defense, the jury needs to comprehensively evaluate the content, academic level, research methods and other details of the paper, which takes some time. Usually, within 2-4 weeks after the defense, students will receive a notice from the tutor or college to tell whether they have passed the defense. Therefore, before the second defense of the VIP thesis system is over, it can't be said that they have passed the audit of the defense team, and they have to wait for the notice from the school or the teacher.
