This question is one of your usual basic skills and one of your mentality. Don't put too much pressure on yourself during the exam. I believe that as long as I have enough training at ordinary times, the exam is no problem. In addition, grasp the reasonable allocation of time for doing questions in peacetime and exams, and clarify the problem-solving skills of questions. Improve your computing ability and try not to lose too many points because of carelessness. There should be no problem!
