This mentality should be adjusted slowly. Even if you don't study in the future, you can't be too anxious when you encounter unsatisfactory things in your life, which is easy to cause problems. Some problems are not clear at a glance. Get into the habit of telling yourself you can do it. Calm down and read the questions several times, analyze the knowledge points to be examined in the questions, and then recall the types of knowledge points that are often tested at ordinary times. If you manage it well, you will have a clue. If you really can't calm down, you can skip this question first and come back later to reconsider.
