First of all, the mentality should be correct. Secondly, according to the college entrance examination mathematics, high school mathematics is the content of chapter 14. The first task we have to do is to sort out this knowledge point as big as a piece of paper, and then the basic knowledge points mainly involve two series, one is arithmetic difference and the other is equal ratio. The first part is their definition. The second is the general image formula. By enumerating five aspects, the basic knowledge of the whole chapter is summarized. Corresponding questions, two frequently asked questions in the series. How to find the formula leading to it? To sum up, there are five common methods. The first is to use the definition of arithmetic sum ratio directly. The second rescue series includes formulas suitable for any series. And this method is the most commonly used when testing the formula of the image. Then there are accumulation method, cumulative multiplication method and construction method, which are summed up and written in another article on this paper. Knowledge comes first and methods come last, so that each chapter will be more convenient to review and get twice the result with half the effort. This is the first point.

Secondly, I think that when we review our mistakes now, we should say that students have done a lot of problems so far, especially the students in Grade Three. One is that teachers at school give students questions every day, and the students themselves don't give up. Some even buy some simulation questions and start doing them. We should pay special attention to the questions we have done and the wrong questions we have done, because this wrong question reflects the loopholes in students' knowledge and methods. By summarizing the wrong questions, you can improve your ability in all aspects.

Thirdly, I think it is also beneficial to read five textbooks carefully when reviewing at this stage. Because the college entrance examination questions can be found in the textbooks every year, the examples, exercises, theorems, properties and proof methods involved in the textbooks will be reflected in the college entrance examination. Therefore, returning to textbooks in this last stage is also advocated by most teachers.

Finally, in the college entrance examination, students are required to have four necessary ideas, namely, the idea of function and equation, the idea of classified discussion, the idea of calculating problems, and the idea of classified transformation.
