When doing exercises at ordinary times, whether you are doing homework, making materials or doing test papers, you should mark them in time.

Mark what? Mark who? Problems that can't be done, problems that can't be done wrong, and problems that are difficult to do (if you can't do it well, you may do it, just think about it for a long time). Mark these three questions. What do you decide to mark, such as drawing a five-pointed star.

These marked questions reflect the loopholes in knowledge and the lack of analytical ability. Solving these problems is the key to improving grades.

At the weekend, do these marked questions again from beginning to end. Circle the five-pointed star if you can. If you can't, draw another five-pointed star next to it, and continue to brush it next weekend.

Second, seriously study the problem, the more you learn, the easier it is.

Learning mathematics well is inseparable from doing problems, but there are endless problems. Although there are endless problems, the knowledge of investigation is limited and the types of propositions are limited. By classifying problems, 70% of them can be reduced.

How to summarize the problem? In the process of doing the problem, it feels like the same kind of problem. Write the question numbers together. You can give this type a name and write it next to the question. It can be classified according to the knowledge points of investigation or the skills of solving problems.

Key issues, difficult issues, big issues and error-prone issues should be carefully studied and then studied. What knowledge should be studied in this question? How to analyze from known information? What are the two analytical processes of pushing forward and pushing back? What are the steps to do the problem? What are the problem-solving skills? Where is it easy to get stuck? After the research, find the same type of questions and draw inferences to consolidate the application. From examination questions to knowledge, from the unknown information of known information, from the past to the bridge thinking. From examination questions to personal thinking, after repeated research, we can truly understand this type thoroughly, so as to achieve the effect of mastering one hundred. Knowing a type will lead to 100 questions of the same type. It seems to take a lot of time, but in fact it saves time.

Thirdly, if there is a third secret to being a top student in mathematics, it is "carefulness".
