Review before the exam can systematize and deepen the knowledge in the first stage, make up for the defects of knowledge, and further firmly grasp the knowledge learned.

(2) carefully examine the questions.

Careful examination of questions means that the conditions and problems related to the information given in the questions should be clarified first, and the problems should be visualized and concretized. We should not only find out the known conditions revealed by Chu, but also try to find out the hidden known conditions; We should not only find out the problems exposed by the demand solution, but also find out the hidden problems of the demand solution. Only by knowing the known conditions and problems can we solve the problems correctly.

(3) Seriously sum up

Through review and analysis, we can find out the defects and weak links of knowledge, make mathematics knowledge more consolidated and complete, find out the causes of mistakes, improve learning methods, and clarify the direction of efforts, so as to make future exams more successful.

Extended data

Review refers to the process of relearning what you have learned. Review includes after-class review and systematic review. The main purpose of after-class review is to understand and consolidate the knowledge learned that day. The main purpose of systematic review is to make a comprehensive and in-depth review of the knowledge learned in the week, month, semester or school year, with the aim of mastering the system of subject knowledge. Systematic review is essentially a relatively concentrated reprocessing process of the knowledge learned in the early stage.

The methods of reviewing after class include:

(1) Review the content and process of teachers' classroom teaching, with the aim of finding out which ones are fully understood and which ones are not, so that further review will have distinct pertinence and purpose;

(2) Review textbooks to deepen;

(3) sorting out notes, supplementing and correcting the incomplete or inaccurate places in the class, making it more systematic and complete and easy to review;

(4) consult reference books or reference books for difficult problems that you don't understand or understand. If you really don't understand, you can ask the teacher or learn to solve it with your classmates.

The methods of systematic review are also diverse. For example, the cycle review method refers to reviewing in time after learning one unit, and then learning the next unit. After learning the second unit, review the two units systematically, and so on. The distributed review method refers to reviewing the learned content in time, and then reviewing it every once in a while, but gradually lengthening the time interval. For example, review what was said in the last unit in time, review after one week, review briefly after two weeks, and review after one month or one quarter. Facts have proved that the effect of designated review is better than that of centralized review. Of course, concentrated review also has its advantages. For example, when reviewing at the end of the term, it is very important to systematically review the key points, difficulties and key breakthroughs in the learning content.
