Personally, I think it's better to have a fine layout and clear and comprehensive problem-solving methods ... If you want to lay a foundation, the math paper is quite basic. I also borrowed textbooks from high school and junior high school to read relevant content, just like that ... I think classics and voluminous books are good if they are logical. Some formulas in the summary volume look intuitive, and there are relatively many questions in the volume. I have also used some published by the National People's Congress. In fact, there were only a few logical questions in the past, so it doesn't hurt to do more. The key is to repeat. It's hard to say anything until the score comes out. It depends on the situation this year. Many people have deducted a lot from their writing … I guess I won't be spared. I haven't practiced writing at all ... Let's pay attention to this aspect.
