However, don't be too nervous. There should be no problem passing the exam. Just do what the teacher says.

The topic selection of graduation thesis is very important. You can't choose a topic that is too hot, lest there is no novel point of view, while a topic that is too cold may lead to nothing to say.

The topic of your defense usually comes from your paper, especially some of the points you quoted need attention. Usually the questions come from here, and the teacher will give you two or three questions. Then you have a few minutes to prepare. During this time, you should sort out the main points of your answer. Don't be cold when answering. As long as the answer is almost smooth, it is estimated that there is no problem in getting a good exam. Even if you don't think the answer is very good, pass it. In short, don't copy the paper.
