Hello, the new world is as crowded as you said, and the learning effect is not good. Only small and medium classes, generally about 20 people, can also explain. In particular, their system of transferring classes, making up lessons and transferring schools is very intimate, and they are all handled free of charge. There is no invisible consumption, and the pass rate is quite high. There were several full marks last year, and Warburg. They are very cheap, but there are fewer courses, nearly 65,438+doors less than Only.
