2. Do more exercises, summarize and reflect. For a problem, method is very important. When you do the questions, you should take them with you. Is there an easier way? Have I used all the conditions? Ask me why I can't do it without asking the question. What knowledge do I lack, and then make up. Junior high school mathematics generally pays attention to the basics, and you also need to master the textbook knowledge completely. On this basis, do some questions in moderation.
It's important to communicate with teachers more. When you are confused, go to the teacher and ask him what to do. After all, the teacher's experience can help you.
4. Adjust your mentality. Don't find math difficult. Believe in yourself.
I hope I can help you!
