There are also requirements for the selection of mathematics remedial classes in senior high schools. First of all, we should make clear the students' own learning level and choose the class that suits them. Secondly, we should choose according to our own schedule. Third: just make an appointment for an audition. Only after listening can we judge whether the teacher is good or not. I don't know if you have seen (Southeast Mathematics). They are really nice. Many students were introduced by classmates, and Yangpu also has a campus. You can consult and see.
