I am a student in Shandong, and my study content may be different. For reference only. First of all, you should know what you are good at. For example, the big questions in the exam are generally trigonometric function, probability calculation, solid geometry, conic curve and so on. Relatively speaking, trigonometric functions, probability and geometry should be as correct as possible, and there will always be steps to write all the big questions you can write. So your focus is on trigonometric functions, probability and geometry. These three parts are relatively basic. You can master the basic types by doing more questions. After all, there are so many problems that it won't expand any more. After all, this is a basic problem.

If you choose, the absolute basic questions of the first three questions are generally inseparable from the transformation of complex numbers, basic geometry and trigonometric functions. It's a bit difficult to ask a few more questions, and you can do it right if you do it carefully. The last one or two questions are high-level questions, so we can give them up and talk about them later. Fill in the blanks on the basis of the same first two questions, the middle is a little difficult, and the last question is high.

70%-80% of a total paper can generally be worked out, and these questions are the first two or three sections of each chapter of mathematics, which is very basic and can be understood if you listen carefully. Obviously, if you are in Grade Three, you must sort out what you learned in Grade One and Grade Two at the beginning. Usually two or three months, you must do it well, and then do the problem. Do the first 60% of each big question carefully before doing other questions. Don't give up, write as much as you can, and there will always be progress. Don't worry, take your time, you can't eat hot tofu with impatience.
