2, fast and accurate computing ability, which is a necessary condition, depends on usual practice;

3, the familiarity of the postgraduate entrance examination questions, the laws summarized by yourself, and the practice to maturity and stability.

4, the mind is flexible and the problem solving is not fixed.

5, psychological control ability

Among them, 1 and 2 are necessary, but this is a slow job, which needs to run through from beginning to end, and there will be no big improvement in a short time.

If you can't remember the formula, you will make mistakes. If the calculation is incorrect, an error will occur. If the calculation is accurate, but it is slow, it will take an hour for the multiple-choice exam, and there will be no bottom behind it. Without a bottom, you will panic and make mistakes.

The tension during the postgraduate entrance examination will greatly affect the speed of solving problems, and the problems will not be solved smoothly, which will naturally lead to more tension and a vicious circle. So you must be able to control yourself and calm down. And don't set too high before the exam.
