2. The content of the postgraduate entrance examination is an independent proposition of the school except for several national unified examinations such as education. The major you want to take is not the national unified examination, but the independent proposition of the school, so you have to buy the target major of your target college, that is, the previous examination questions of China politics, civil and commercial law, and the ideas and test sites of the research topic.
3. First-class schools will not publish the list of tutors before the initial test, and so will Zhongzheng. Don't worry about the problems of tutors, you can learn slowly. Find or drag classmates, acquaintances, relatives, etc. Find the elder brothers and sisters admitted in the past on the BBS of Zhongzheng to introduce you to the tutor. The tutor's books and opinions may only be involved in the second interview, but generally not in the first examination (with few exceptions).
I am here for the time being. I wish you an early review and good luck!
