I took the 13 postgraduate entrance examination for mathematics, and then I enrolled in Wenhai's mathematics class. Wenhai's postgraduate teachers are all well-known universities in China. Wenhai's math teachers are Tiejun (like, focusing on advanced mathematics), Dr. Zhao, He Xianzhi, Ye Shengbiao (cute little old man, focusing on advanced mathematics, unique passion) and Zhang (focusing on linear algebra and advanced mathematics). You can go to official website to see this. Wenhai's teachers are all from China, but each teacher has a different teaching style. For example, in the summer vacation, this teacher talks about advanced mathematics, this teacher talks about linear algebra, and another teacher talks about probability theory. Wenhai has no internal unified teaching materials (except politics), and each teacher is an independent handout. This is one of the reasons why I like Wenhai best. Every idea, method and problem-solving skill is different, and the gains are different. In addition, Wenhai's lectures are particularly efficient, and every teacher can grasp the key points in a short time and improve the ability to answer questions. It is also required not to advocate crowd tactics and wheel warfare, and the total class time is not very long, which is conducive to reviewing the arrangement of the plan. In addition, when I was an undergraduate, many other students took the postgraduate entrance examination in other mathematics counseling institutions, but they only focused on mathematics, so the time for reviewing other things was greatly reduced and there were many notes. Personally, this is not conducive to the coordinated use of time. In addition, if there are partial subjects in the postgraduate entrance examination, you can allocate your time to the weak subjects appropriately. Politics and professional courses can be taken after September, and the basic review of mathematics and English can be advanced to March and April. The front line should not be too long, otherwise it will be easy to get tired, so pay attention to the combination of work and rest.
