As far as online classes are concerned, the overall training in Gao Dun is OK. Compared with other schools, Chinese class is ok, but the overall style is old, the average age of teachers is old, and the teaching method is not suitable for young people. The teaching materials and handouts of Dongao are ok, but there are still some shortcomings. The update before the exam is a bit slow. Gao Dun's online class experience is really ok. CPA is a persistent competition, and the time cost paid by individuals is very huge. If I give up halfway, the loss will outweigh the gain, and I am not very active in my study. I want to give up many times in the middle, but the inspector in Gao Dun is very fierce, just staring at you to plan the course for me, whether it is class or service.
