Children's math and physics in the second day of junior high school are hovering around 70 points. Relatives recommend going to Huahai Square Campus of Changzhou Happy Learning Education. Is it necessary for us to have a one-on-one meeting in this situation? If the score is around 70, it depends mainly on the progress of children's schools, such as Chen Xing, Zhongtian, Academy of Education, etc. These three schools have made rapid progress and the teaching difficulty is relatively high. For schools with fast progress and high difficulty, one-on-one is recommended. In other cases, one-on-four can be used. Of course, if conditions permit, it is best to go one-on-one, because one-on-one is indeed the closest to the actual situation of children from a targeted point of view, and the effect is also the best.
