Because more than 60% of the questions in junior high school mathematics papers are relatively simple, there is a lot of room for improvement. In the first half of the third semester, the teacher should listen carefully in combination with the general review knowledge points. It's best to learn, but it doesn't matter if you don't understand. You can specialize in modules in the second half of the semester. If the score is above 10, the goal is to focus on simple questions, such as the first seven questions of multiple-choice questions, the first three questions of fill-in-the-blank questions, the big questions behind, simplification and evaluation, practical application and trigonometric function. It's not too difficult, even if there is no foundation, just work hard. Let your classmates or teachers tell you first. I feel that I will start to brush the first question after I get started. If I can't brush it ten times, then I will brush it ten times. I will know the first question and start the second one. Remember to understand the wrong questions in the middle. If you don't understand the wrong questions, it's useless to brush more questions.
