In fact, I have graduated from graduate school for many years, and I may have the same concern about the topic. At that time, I was worried that I couldn't get into the exam, or that my scholarship would be affected and my grade point would be affected.
In fact, no matter in study or in life, the mistakes made in the past are gone forever, and it is generally difficult to go back and make up. It is better to take it calmly and wait for the result than to be unhappy and worried all day. If you don't hang up, then it is the god of luck who patronizes and is grateful; If you fail, then review your own shortcomings and try not to make the same mistakes in future study.
Maybe you will say, say a lot of words, but none of them are comforting and affirmative. It's all true, but it really works. These principles, which were ignored in the past, will gradually become the true meaning of the heart, whether in future study or in work after graduation.
