1, accumulate ideas for solving problems

In addition to the basic knowledge of mathematics and formulas, in fact, every problem has a disintegration idea. The change of problems usually requires you to change your thinking of solving problems, which is also accumulated. For example, if you have been doing a trigonometric function problem, if you have been doing it with the same idea, but suddenly you need to change the method, then you need to write this problem down. These steps are urgent, slowly accumulate and stick to it.

2. Master the basic knowledge.

Some students feel that they have mastered all the knowledge points, but they will never solve the problems in the face. To put it bluntly, they lack the ability to use knowledge to solve problems. Therefore, in the process of mathematics learning in Grade Three, students with weak foundation should take notes, such as the key ideas, methods and skills of the teacher to explain the problem.

3. Reasonably arrange the time and order of answering questions.

During the exam, it is common for many students to finish the exam, and there are still many problems to be done. In fact, the main reason for the 30 points in junior high school mathematics is that there is no reasonable arrangement of answering time. Before the exam, students should put the exam time and the characteristics of each question type.

4. Pay attention to common formula skills.

To understand the ins and outs of commonly used mathematical formulas, it is necessary to further understand their reasoning process and explore some possible changes in the process of derivation. Necessary training should also be given to the knowledge and skills necessary for further study and common sense often used in daily life.
