1. The question of thesis defense is that the teacher asks questions according to the content of the thesis topic you choose.
2. My thesis defense experience is to introduce myself first, then introduce your thesis title, and summarize your thesis for 3 minutes.
As long as you read your paper thoroughly, it is easy to read the outline and abstract of the paper. The questions asked by the teacher are all aimed at your paper.
Take it easy. Good luck with your defense.
