In the process of defending the thesis (design) of university graduation (including junior college, undergraduate, master and doctor), for some reasons, the thesis (design) defense failed. In order not to affect graduation, students who fail in defense are given another chance after discussion by the defense Committee (or the degree-granting Committee), which is called "second defense".

If the second defense is successfully passed, it will not affect the diploma and degree certificate, and students can successfully get the degree certificate and diploma; However, if the second debate still fails, graduation may be delayed or delayed for half a year, which means that you can't get your degree certificate and diploma on time.
