Don't worry. If you want to get better grades in your thesis and apply for a degree or something, you can talk to your teachers, who will usually handle it.
Actually, it doesn't matter if I don't say it. I didn't work hard, and even got more than 80 points in my thesis. The key to the self-study exam is the process of the exam. The requirements of the final paper are not very strict. Just don't worry too much, but write well.
Of course, it does not rule out that some colleges and universities are particularly strict with the requirements of papers. Therefore, we must have a correct attitude and write a good paper. Hehe, I hope it will help you a little!
