In fact, the defense is generally not too difficult, so don't worry.
Question 1: Where did the data in the paper come from? What about charts or something? Is the data true and valid?
Question 2: the format is wrong, the font is wrong, and the paragraphs are not well connected.
Question 3: Is the scheme design reasonable? Is it feasible? This problem is the most important and one of the main problems. )
Question 4: Does your school require PPT, handouts and the like? If there is, pick a bone. They usually ask why they can't be more perfect.
The above is my personal defense experience.
It's really not difficult to reply. Usually give it. Even so, there are still two chances to argue.
Also, the most important point is that you must answer the questions asked by the teacher. No matter whether the answer is correct or not, you must speak. It's okay to answer irrelevant questions. See? Just can't let him freeze.
Those who don't talk and say they don't know are taboo in reply. Remember.
Finally, I wish LZ a smooth defense! Success!
