No, it's not. To put it bluntly, it is an opportunity, and so is the exam. Many candidates like to sharpen their knives one week before the exam and begin to recite the questions before the exam. This state is very unfavorable for the exam. Because if you don't review the exam preparation in the early stage, you will think that a set of ordinary test papers is a bet before the exam, and regard it as an artifact of scoring, which is very unfavorable for the exam. The most important thing is to be steady and steady at ordinary times, and don't panic in the exam.
