Show modesty, such as "I didn't think too much about this question, I really don't know, you just made it up when I met the teacher today" or "I was confused about this question at that time, so I asked it, hoping the teacher could explain it."

This is for instructors and an important part of defense. Don't think that just guiding the thesis and not participating in the thesis defense will have little influence, but it will have the greatest influence. Even if the defense team teacher thinks it's not good, but is willing to give it, it can still pass.

So it is very important to give the tutor a good impression of positive efforts. Talk to him more, brush your sense of existence from time to time, know that you are working hard, and don't let him feel that he doesn't work hard every day and it is difficult to reply. In short, give the teacher a good impression.
