Mathematics is actually very complicated, and there is no physical and chemical system, so you have to sort it out yourself. My classification falls into two categories: tools and key points.
Tools are sets, logics, inequalities, vectors, limits, trigonometric functions and combinations, and probability and binomial generally do not cause big problems. It is characterized by scattered knowledge points and strong applicability. It is not difficult for a single problem, but once it is synthesized, it is not simple. For example, analytic geometry and vectors, series and binomial, series and inequalities, derivatives and vectors are all finale problems. Don't do too difficult questions in this kind of review, do more to achieve proficiency, and at the same time ensure that you can fill in the blanks quickly and lose less points.
There are four key points: sequence, function and derivative, analytic geometry and solid geometry. If you learn space vectors, it will be difficult to synthesize them. I suggest you have a notebook to write down the teacher's conclusions and questions. Although these conclusions can't be used directly, they can provide ideas. After remembering the proof, they are equivalent to direct use. At the same time, it is best to consult the teacher and do the questions that suit you, because these questions are as difficult as them.
As you have just entered the third year of senior high school, I suggest you keep up with the teacher's progress and pay attention to the foundation. Don't just ask, don't press. You don't have to use the wrong questions, but you must write down the questions and conclusions in the wrong questions, but don't do the same questions over and over again, but do the same questions over and over again.
If you have a calm mind, the college entrance examination is a top-notch exam, and the questions used are not for people. I suggest you look at the math scores of your classmates in the same ranking. If the average score is still the same, then don't be nervous, study hard and use the right method, and you can improve completely. If you are dragging your feet, don't worry. If you drag your feet, you must be top notch. You should learn to transfer the learning methods of superior disciplines to inferior disciplines and make progress.
Good to see that you really want to improve. Only when you have a goal can you be motivated, but don't be impatient. Rome wasn't built in a day. If you fail, don't deny yourself. I suggest giving myself exams constantly, that is, doing problems in a limited time. Doing well can motivate yourself. If you don't do well, you will find shortcomings and you can constantly improve.
Finally, believe in yourself and wish to be admitted to an ideal university!
