Three points for strength and seven points for luck in the exam. Listen carefully in class and don't panic when you encounter problems in the exam. At that time, when I was taking a comprehensive literature exam, the teacher posted the bar code to me, and I tore up the answer sheet as soon as I pulled it. Fortunately, I told myself not to panic and play normally, just waiting for the teacher to correct the paper. When I took the math exam, I found that some big questions behind me were unheard of, because I was better at math, so I still told myself not to panic. You can't afford it, and more people can't afford it. I will try my best to do it. I can't dwell on a big problem. The first three or four big questions must be done correctly. The next one is a small problem or a small problem, and the rest is done. If the amount of calculation is large, it will not be the result and earn points. Be sure to choose half an hour to fill in the blanks. The last one or two of the multiple-choice questions look at personality. Do it if it's simple, but don't spend too much time.
