I think the most useful way is to let yourself think nothing and empty your mind. There are many ways to do this, such as taking a deep breath, running before the exam, and leaving enough time for your breathing to calm down. Another way is psychological suggestion, which is not contradictory to give yourself a beautiful vision and lower psychological expectations. Let's talk about it in combination with our own experience.

Take a deep breath. Some people think that deep breathing is of little use because it is not used in the right way. I used to be like this. Just take a deep breath and sink your breath into your abdomen. Don't look half full of dissatisfaction. This can only be considered as moderate breathing or shallow breathing, and the effect is not obvious if the gas is not enough. As you can imagine, you can practice by increasing the surrounding air, but you can only take one breath, and you will definitely try your best to breathe.

Then talk about running. Jogging is actually a long breathing process, so it will also make people feel relaxed and happy, but you should do what you can and just run casually. After all, there are exams, so the requirements for the world are relatively high, and there must be a certain world.

Positive expectations, such as eating delicious food after the exam, even if you don't do well in the exam, your parents will cook you good food, and your classmates and teachers will encourage you to make progress next time. No matter whether these will come true in the future, at least you will be happy and forget your troubles.

I usually write refueling on the draft paper I send. Nobody cheered for me, so I cheered for myself. This will also ease the tension.
