Everything is fine. I personally like this style. Bai Ge's class style is lively, the class is clear and easy to understand, the lecture is mainly based on problem-solving methods, and he is good at summarizing questions. Teaching is difficult to some extent, with difficult problems, finale questions and error-prone as the core. Jiang Mumu's teaching style is rooted in writing logic and English language logic, and based on the law of college entrance examination, helping students to accurately attack the test sites of college entrance examination.
