I think junior high school mathematics is still quite critical. As one of the three major subjects, my math scores are not good, and my grades are too serious. The level of mathematics I teach is getting higher and higher. They have Jiege deciphering mathematics in the middle school entrance examination. When I first came here to study, some of them couldn't keep up with the rhythm. At first, I was not sure. Later, I followed the teacher's arrangement and was willing to ask questions on my own initiative. Slowly, my grades began to improve. I just passed math before, and now my math scores are among the top in our class. Some students specifically asked me what class I enrolled in, and now several students want to study in higher education.
