Expanding reading: we must master the formula of scoring skills in mathematics for senior high school entrance examination.
Mathematics examination paper, no matter what kind of questions it is, is a flexible use of questions and formulas in books. Therefore, mastering formulas and theorems is the basis of mathematics review. When doing the problem, if you don't have any ideas, you can think about which chapter of the problem is similar to the previous textbook and see if it can correspond to the corresponding formula.
Pay attention to do more exercise.
If candidates want to get good grades in the exam, it is necessary to do more exercises. By doing the problem, we can have a better grasp of the formula theorem, and at the same time, we can analyze from which angles the questioner will investigate, so that we can learn and use it flexibly when encountering similar problems.
It's easy first, then difficult to solve the problem.
The order of doing the questions follows a principle: easy first, then difficult. The structure of a test paper itself is gradually developed from shallow to deep, so when candidates get the math paper, they should try to do it in turn to avoid starting with big questions first. Give up when you encounter a problem that is too difficult, and then do it when you have time to finish other problems.
