It's simple. At the beginning, I wrote that the exam was very general, who was my goal and how many points he scored, but how many points I scored. I analyzed it. I learned this part very carelessly and seriously. I don't know many details and I'm not very good at it. As a result, I didn't keep up with the teacher in class. If I don't understand it, I will forget it. I was too lazy to ask my teachers and classmates, so I didn't ask. ..... Yes, I am very sad myself, so I challenged my target classmate, and I must surpass him next time to get a high score ... Finally, I promised myself that I would study hard next time and I would put myself in such an exam ... You can look at some places again, and I can only help you in this way.
