2. Never write something you don't understand, pretending to be profound, which is easy to be asked to death by the teacher.
You'd better write something yourself and get familiar with it.
4. The topic scope should be as small as possible, and it is best to be specific to a certain equipment. The bigger the topic, the wider the scope of the teacher's questions. Teachers usually give two or three topics in their papers, and the papers give one or two topics. The topic should be small to ensure that the questions in the article can be answered.
The downloaded papers written by others are useless, because it is better not to hand them in and defend them. It's not your own. You'll die if you ask.
6. Don't simply copy the instructions.
7. When writing an article, there are some difficulties that must be made clear. When writing, you should deliberately write vaguely to induce the teacher to ask questions in these links.
The above is my experience in writing a thesis, and I hope it will help you.
