First of all, when the students come to the school district, the old math teacher will find out the weak points of the students by analyzing the form of the previous test papers, and make a study plan for these weak points. On this basis, through the lack of knowledge in the classroom, let the children know the defects. After class, students are given answers after class through the unique way of one-to-one teacher serving students, so as to maintain their learning behavior and finally achieve the goal of scoring.
