Why did my math major make mistakes in the senior high school entrance examination? I think when it is difficult for the brain to write questions calmly, it is easy to be disturbed by the outside world. The more afraid I am of failing the exam, the more I care. If you care too much, you will pursue perfection and expect all the conditions in the exam to be perfect. Once you can't, you are afraid that those things will interfere with you, and you will pay special attention unconsciously. Relax and tell yourself that you can't always have such perfect conditions. Even in the college entrance examination, if you are not careful, there will be car noise. Students who move too much will creak their chairs and walk under supervision. Everything is normal, because it is too common, so it won't affect you at all. Let's just say these are inevitable. Are you good at math? Well, you don't have to be afraid. I still listen to songs when I do my math homework. Relax and be confident.
