Value: 1- Check the missing parts. Through the review in the past few months, the students have basically mastered three knowledge points, but there must be some unfamiliar weak links in some chapters, some knowledge points and some questions. Therefore, through the practice of real questions, you can find your own shortcomings. At this time, you can read the wrong notes or review the notes to strengthen the weak links again and practice again.

Value two-strengthen key problems and improve the proficiency in solving problems. Systematically study the real questions in recent ten years, compare them repeatedly, eliminate the knowledge points with the highest repetition rate, and strengthen the understanding of the corresponding basic concepts and theorems. Cultivate the "feel" of doing problems and ensure that you can go to the examination room in the best state.

Value three-study the real questions and summarize the rules of the questions. We should not only strengthen our knowledge through practice, but also study the law of real questions in recent years, consider the ideas of the questioner and boldly predict the test sites.
