Teachers are very strong. Du Wen has been a postgraduate tutor for so many years, and has trained many excellent postgraduate teachers. As mentioned above, many famous teachers have jumped ship from other institutions. But in fact, Du Wen has trained a group of teachers himself. The standards for recruiting lecturers are very high, and they must graduate from prestigious schools and go through layers of screening. In the end, only 2% people can be hired.
In fact, it can be seen from their lecturers' resumes published in official website. I applied for a comprehensive course. Chen Jian, a math lecturer, is a doctor of mathematics in Tsinghua University, and has more than ten years of postgraduate counseling experience. Tian Ran, writing lecturer, master of Guanghua School of Management, Peking University. Although he is young, he has been doing postgraduate counseling for several years.
Therefore, in fact, the better postgraduate institutions have strong teachers, so you can see which training method you are suitable for. I think Du Wen's service is excellent in postgraduate institutions, because they are a dual-track teaching mode of large class teaching and one-on-one tutoring. Outside the normal class hours, there will be 24+7 one-on-one tutoring by teachers. This is beyond the power of many large institutions in the market.
