If the junior high school mathematics foundation is solid, it will help to improve the interest and confidence in senior high school mathematics learning. The content of junior high school mathematics learning seems to be function and plane geometry (triangle, circle, etc. ) it has a great influence on senior high school mathematics learning, and I don't know anything else. High school mathematics pays attention to understanding and training, which is theoretical and coherent that junior high school mathematics does not have. Therefore, we need to thoroughly understand the textbooks, deepen the understanding of concepts, and train the necessary points (knowledge points), write down the questions that we will make mistakes or not, and do them again and again. In the end, practice makes perfect, and step by step, I believe your math scores will be improved. According to my own experience, I suggest you go to a math tutorial class for senior one (but it seems too late now) or take a look at this compulsory math class for senior one yourself, so that you will be prepared and begin to explore the learning methods of senior one mathematics. If you are always ahead of others, you will learn much easier.
