Junior high school is a quadratic function. Girls are generally not interested in mathematics. If the training course is one-to-many, the effect is not very good. I think we should find a tutor or a one-on-one teacher to cultivate her interest and inspire her to think. If we simply take exam-oriented education and instill knowledge, it will only be counterproductive and make her hate mathematics even more. When I was in college, I worked as a part-time teacher in an educational institution in Zhou Pu, Shanghai, and met many classmates. Some students take the initiative to study, and the learning effect is very good. Some are coping, and a lot of knowledge is not really understood and applied. Later, I took three students. Personally, I think we need the patient guidance of teachers and the motivation and initiative of students to learn by themselves, because the education in China is not perfect at present, and the quality of a student is measured by scores and achievements. It is important to advise her to study happily.
