Secondly, the examination status. Some people are not nervous about exams, but they are nervous when they get to the big exam. When they are nervous, they will make mistakes.

Thirdly, it should be the innovation of the question type. Before the college entrance examination, you won't do the original question. In recent years, there are more innovation problems. Maybe you haven't even read the questions or rarely do them, which creates a great obstacle for those who brush the questions instead of understanding mathematics. Therefore, learning mathematics is mathematical thinking, not just brushing questions.

This is my opinion, I hope to adopt it, thank you!
