1, the basic knowledge must be memorized, for example, the theorems used in proving problems must be memorized (it is best to memorize them).
2. Listening to the class is not completely like taking notes on the teacher's blackboard. You should listen first, then understand, and finally write down what you don't understand and ask the teacher.
3. If you can't understand in the course of the teacher's lecture and find out what you don't understand in time, you need to preview it, so that you can effectively complete the second point.
4. You can't just do one kind of problems, but also touch different types of problems, such as the combination of geometry and algebra. Remember that problems with similar methods of solving problems are only used to exercise calculation or familiarize yourself with concepts; Understanding means that if you have more contact and broaden your horizons, you can look down on the topic from a high angle, find more solutions, and even find the irrationality of the topic.
The biggest difference between high school mathematics and junior high school mathematics is systematicness. High school mathematics is very systematic, so it will lead to the first paragraph not being understood and the second paragraph not being understood. About stupidity, it's actually not a big problem. Can be admitted to high school normally and have normal intelligence. The most important thing to solve these problems is to grasp the foundation. Go back to the textbook. Don't look down on textbooks, thinking that things in textbooks are simple and unwilling to learn or write. In fact, most of the topics are adapted from textbooks.
Moreover, after entering high school, the difficulty of textbook topics is not the same as that of junior high school classes, and many textbook topics are still very difficult and worth writing.
From the perspective of thinking, junior high school mathematics is mainly imitative thinking, while senior high school mathematics is mainly creative thinking, which requires students to draw inferences from others and find different and identical laws. Junior high school can get good grades through practice, while senior high school relies on enlightenment on the basis of practice.
