1. Mathematics learning focuses on thinking, and the highest level of mathematics is to draw inferences from others. It is not easy to reach this state. My method is to compare different questions applied to the same method and summarize their similarities and differences. After thinking, I will naturally have an extraordinary understanding of it. 2. Set up a set of wrong questions to collect your own mistakes. Take it out when reviewing, and you will get good grades in the exam. 3. Make a simulation paper before the exam, the test paper is almost the best as the real question, increase your self-confidence and better adapt to the examination room; 4. Turn over the books frequently, recall the vague concepts immediately, and mark them well.
The above is the math learning method I gave you. As for your question, I think most people can't answer it responsibly. I have used the materials of Longmen Bookstore, and I feel that its books are difficult, a little divorced from the college entrance examination, and many places are particularly complicated in calculations and so on. If the college entrance examination is not good, it is not recommended. I heard the latter information for the first time. Without practice, I have no right to speak, so I can't evaluate. I recommend you to use the star series "Research on Test Questions", which is close to the college entrance examination, keeps up with the trend and explains it in place, only a few yuan each.
We can communicate again if we have specific questions. Good luck!
