There are no basic classes in Fang Hao. Teacher Fang Hao has been devoted to the research and teaching of postgraduate mathematics, and the young representatives who teach postgraduate courses have created a stage review strategy, which has benefited students a lot. No matter how complicated the mathematical theorem is, it will be transformed into simple basic knowledge if it is spoken in a few words. Less class hours, high efficiency, the source of the topic, the evolution of classic questions, and flexible problem solving will make the listeners feel relieved and condescending. Moreover, the types of courses it teaches also include basic courses, and zero-based courses can also participate in registration.
