I remember that math was poor in junior high school. Our head teacher is a math teacher and a very simple and honest teacher. Because she teaches fast, we math idiots don't understand it. One lesson after another is a failed test paper!

So some of us just want to make amends. We asked the math teacher if there was a teacher who could introduce us, and the teacher said I would make it up for you. Later, I went to make up lessons for my teacher, and I went all day and afternoon on Saturday, and I made up nights from Monday to Friday. Teachers also help students in other schools with their lessons. Together with the five of us, there is a team. We asked other schools how to calculate tuition fees. They said that one hour is 15, and we will give the teacher money after one month. We were embarrassed that the teacher refused to accept it. After all, there are five people who go to make up lessons every day. I didn't expect the class teacher to say that you are my students, and my poor grades are my responsibility. How can I accept your money and get it back quickly! Later, we worked hard, always in vain. The teacher helps us make up lessons. Few teachers are so conscientious now! I will never forget having such a good teacher. ...
