Actually, you don't have to do this. Since they think you can't do it, you have to work hard and show them. Besides, you laid a solid foundation in primary school. Middle school is a hurdle. At first, you may feel a little uncomfortable. You should have a stable attitude towards the exam, understand it thoroughly, and always think about math. Always use your head to grasp knowledge points in class. Junior high school is not as simple as primary school. Many questions are designed for you to jump in. Don't underestimate any subject, because they are all important. Like you, I am a middle school student. Many of us don't work hard. Why? That's because they don't want to learn, and they don't know if they want to learn. But you are different. You have your dreams and pursuits. You can go up and show them your attitude and spirit. It doesn't matter. You may not be sure about some points. Only don't give up, don't give up, turn learning into learning, and turn learning into learning. Be sure to show your attitude in front of the teacher. Since you want to learn, the teacher won't say anything. If you have any questions, ask me.
