First of all, I want to say that it is easy to be subjective to evaluate whether something is good or not. It is better to give advice from others than to experience it yourself. One-to-one counseling institutions will vary from person to person, and people's understanding ability and learning ability will have an impact on the evaluation given. But objectively speaking, 100 education is above average among many educational institutions in the market. What I know is that their textbooks, teaching methods and teaching tools are all developed by themselves, which is different from similar institutions in the market. As for the teaching level, it is still the above sentence, and it is better to verify it yourself.
