I just attended the course introduction of the remedial class yesterday. Listen to the introduction. This course should be effective. The child took part in a language test to test the mastery of knowledge points, and then said that targeted counseling can be given according to the child's shortcomings. But the cost is really too high. The fees in the form are for single subjects, that is, Chinese, mathematics, English and physics are charged separately. Our small county town on the 18th Line has a limited family income and simply cannot afford it.
