This is a common phenomenon, not just Mr. Tang. If you are just in good shape, you have worked hard but have spare capacity, no matter how high the upper limit is, you should try to add something. However, I also have some views on strengthening Mr. Tang. Because I don't like his lecture notes and complete works, I recommend that Mr. Tang's lecture notes be combined with the complete works of Li Yongle (or other teachers' counseling books).
Some students say that the problem is more intuitive, but this is only a framework. Compared with the lack of analysis, it can be considered as yoga. For example, I have seen many teachers Wu Zhongxiang neglect exercises because Wu Zhongxiang's lecture notes are not detailed enough. It was not until I showed him the handout of Tang that he burst into tears and said that Wu's handout was really a conscience. Can't I do it? In short, although I don't quite understand why there is an upper limit, the problem of the topic can be solved by adding a set of counseling books. Even if there is a reinforced ceiling, there are books such as Li Lin 108 Zhang Yu's retreat to strengthen the transition of the real topic, and there are simulation questions behind the real topic. There are so many opportunities to break the upper limit, and now I'm afraid there is an upper limit.
In response to this problem, Mr. Tang said: What suits you is the best. If you like my class and think it can really help you, you can be alone with me. As long as you follow me closely, I believe you can achieve satisfactory results. If you think my course can't help you or achieve the desired effect, you can also find a course that is more suitable for you. My attitude is to work wholeheartedly for the children, and I believe I can lead everyone to success.
