Ok, the all-round classroom test center training mathematics junior high school all-round classroom is good. Extracurricular knowledge. Class A is rich in extracurricular knowledge and has a good expansion, while there is little extracurricular knowledge and expansion in test center training, so class A is good. Question type. There are many types of questions in straight-a classes, which is beneficial to children's thinking, while there are few types of questions in training centers, which is not conducive to children's thinking. The top class is good.
