1, you don't have to worry. The defense is nothing more than a process. As long as you are familiar with the paper, the questions they ask are all around it, as long as you are not scared to speak.

2. 1 handwritten paper, 2 copies.

You look worried. You are so tired that you only earned ten points. Here, give you a hand. Just be specific. It's up to you whether to chase or not.

Defence process:

When you reply, first introduce yourself briefly, and then outline the general content of the paper, but just recite it. Read the content for about 3-5 minutes, and then the teacher will ask questions about the content of your paper. At this time, if it doesn't work, it's best not to leave the rink and try to say something reliable. Teachers usually ask 4-5 questions. Then it's over. If there is anything wrong, the teacher will say it on the spot and ask you to wait until others have finished. Only a few people need a second defense, but the second defense is absolutely passed. Don't worry, it's okay!

By the way, I despise those little whites who talk without nutrition.
