Do it three or five times with your heart, and you can basically understand the knowledge points involved in this set of questions.

If it's a backrest answer, or if you don't use a pen to follow the exam specifications dozens of times, it's a waste of time.

In fact, there are still many knowledge points and various changes in the college entrance examination papers. Therefore, it is necessary to conduct repeated mock exams for many years to understand a considerable part of the college entrance examination papers. However, it is best to go deep into yourself and understand the relevant knowledge groups.
