Teaching material recommendation
The teaching materials only need the Guide to the National Postgraduate Entrance Examination for Master of Laws (Illegal) published by the National People's Congress (hereinafter referred to as the Guide) and the Analysis of the National Postgraduate Entrance Examination for Master of Laws (Illegal) published by the Ministry of Education (hereinafter referred to as the Analysis).
subject of examination
It's just the national unified examination and the unified proposition of the Ministry of Education. You don't need to choose a direction. Just choose the school you want to take. After the second interview, each school will give its own questions, and generally take the contents of the initial test (except for cattle schools such as Peking University).
Exam preparation experience
As for other teaching materials, experiences and so on, I suggest you go to the major postgraduate forums and have a look. They are all comprehensive. You can download some materials from previous years, as well as the audio of various remedial classes, which is very useful. It is suggested that Baidu visit the LLM Alliance, the knowledge treasure house and the Postgraduate Entrance Examination Forum to find the corresponding sections.
