You should have noticed that the problems in mathematics are relatively dead. For example, the question 17 is about taking trigonometric functions, so I suggest you review mathematics in this way: review the textbook according to "topic-content, content-topic" and understand and master it one by one. For example, if you can't do probability questions on a test paper, don't worry, pick up the textbook and slowly learn to understand all the contents of probability, and then go back to the test paper to do probability questions. (It is recommended to fill in the blanks first, and don't do the comprehensive questions later. This is not the right time. Don't worry, we'll talk about it later. The same is true for other topics, one topic, one content and one content. Remember: it is better to break one finger than to hurt it, and it is better to do a good job in a category than to deal with all the topics in general.
It's time to talk about the big topic behind. In addition to mastering the corresponding textbook knowledge, we should also pay attention to understanding and summarizing the problem-solving ideas of big problems. For example, one of the big problems is to find the range of derivatives and parameters (or solve others). Take out all the math test papers, first calmly recall the contents of the textbook (concepts and formulas), and then get to the point. After understanding the question, start to answer. First of all, you must answer according to your own understanding, and write as much as you can. If you can't answer (assuming you can't do it), you have written down the answer), just look at the answer, understand every step of the answer (know why it is like this and what it is for), and then study this kind of question on another test paper.
In this process, you should hold your breath. Mathematics is not accomplished overnight. You should take your time and comb your hair. You should focus on the college entrance examination. Don't pay too much attention to the results of the usual mock exam, although it feels bad after the exam. You should have a mock exam with a purpose, find out your own details from the mock exam, know yourself and know yourself, and win every battle. This is too general. Let's give two examples. Everyone does this problem at a different speed. What is the correct rate if you do it quickly? What should I do if I do it too slowly and don't have enough time? This should be paid attention to and exercised in the usual mock exam; Also, the order of doing the questions also needs attention. Some people like to do big questions first, others like to do small questions first, but what kind of order to do the questions is suitable for them is also something that should be paid attention to and discussed in the usual exams. You may say that these can be clarified in the usual tests. But these are just two examples, and there are many other aspects and details, and details determine success or failure. What I want to say is that it is different from the college entrance examination at ordinary times. Give you a test with last year's college entrance examination paper, and your grades may be better than the last college entrance examination. Then you might think, it's not hard. Why didn't you do well in the last exam? Why? Because of the environment! The college entrance examination determines whether you can go to college or not. In the examination room of the college entrance examination, such a background, two to two and a half hours limit, will naturally lead to such a result. But you don't have the atmosphere of the college entrance examination now, so you'd better exercise in the usual mock exam.
I have been teaching myself since I was a sophomore. The above are my personal and effective learning methods, regardless of mathematics, physics, etc. Here is a reference for you. At the same time, remind everyone that everyone has their own learning methods, and what is effective for others may not be suitable for them. I hope you can find the most effective way to improve mathematics as soon as possible, and don't forget to keep the improvement and stability of other subjects. In short, the weak will make up, and the strong will be stronger!
