This stage of the course is an exam-taking course, with a high starting point, a certain intensity, and a combination of lectures, exercises and assessments. Candidates are required to keep up with the pace of the course, and timely preview and review, homework and completion stage assessment standards.

　　Avoid misunderstandings in professional course review

　　Candidates and students can refer to the above review methods to study. At the same time, it is also necessary to avoid the following three main misunderstandings:

　　1. According to the plan of ordinary colleges and universities preparing for the exam, professional courses are reviewed later

　　The depth, breadth and flexibility of the examination are higher than those of ordinary colleges, and the test center is changing every year although it has been represented; the results of professional courses are very important and account for a large proportion of the initial examination and the re-examination, and the late review of professional courses often leads to insufficient time to adjust after discovering the difficulties, and the difficulties encountered in the review are easy to wear out confidence. Therefore, Shengshi Qingbei specially reminds students that making correct preparations for professional courses is the biggest key point for being admitted to Tsinghua University and Peking University. This is a major difference between preparing for the exam for ordinary colleges and universities and Tsinghua University and Peking University, and special attention should be paid to it.

　　2. Pay attention to the intensive question-making stage, but not enough attention to the basic stage review

　　If the review in the basic stage is not solid, there will be a large number of knowledge loopholes and blind spots, which will be reversed to make up for the foundation, which will seriously affect the review effect of the intensive stage, affect the review progress and the confidence of the candidates. In addition, there are more implicit test points in the actual distribution of content in the basic review. When it comes to basic review, some candidates will think that the foundation can be seen by themselves, and the result is often time spent, but in September and October, they still know a little bit about it, and when they do the questions, they either don't know where to start, or they can't answer completely, or the speed can't come up, or the whole knowledge point is not strung together. The exam questions of Tsinghua University and Peking University are not absolutely difficult, but the requirement is to use them flexibly on the basis of solid mastery. Therefore, the three rounds of the three-level curriculum system of Shengshi Qingbei pay special attention to the arrangement of the combing stage of the test center, guide the examination students to pay attention to the foundation, lay a solid foundation, do not think that I understand what I read and read and think I understand, and the inefficient learning that seems to understand is a waste of valuable time.

　　3. I want to focus on revision like I would like to prepare for the exam in a regular college

　　Ditto, although the examination questions of Tsinghua University and Peking University have been reproduced, the depth, breadth and flexible application of the examination requirements are higher than those of ordinary institutions, so it is impossible to effectively deal with the examination of Tsinghua University with the same focus on review as ordinary colleges and universities. If you don't take the test in previous years, you may take it this year, and if you take it in previous years, you may not take it this year or combine it. There should be focus, but there should be no expectation of focusing. Speculative mentality, looking for a relationship to get the question, don't think about the question, everything changes, the more famous the school, the fairer, and a solid and comprehensive review is the attitude that the exam should have. Therefore, in the three-round three-level curriculum system of Shengshi Qingbei, the stage of special questions is planned to help students focus on breaking through and mastering the core test points in the form of special questions, supplemented by practical training of sets of questions, so as to respond to changes.

　　4. Copy the experience of your seniors

　　The seniors who are admitted have their own strengths, but we should pay attention to the application of experience, and the seniors will always have some inconveniences or problems that we are not aware of or lack of systematization may cause us to fail. Why do so many people buy materials, but I don't get in? The situation changes every year, and with fragmented experience, it can't really guide our learning, and even misleads. The price of free or cheap may be our year's time, and we should pay attention to the experience of being open to accepting but dialectically absorbing seniors. Shengshi Qingbei has focused on Qingbei for nearly 10 years, absorbing successful cases and counseling experience over the years, summarizing and refining the three-round three-level curriculum system to avoid detours.
