Question 1: Like your liberal arts major, you should choose two professional courses, politics and English. Politics and English are subject to the national unified examination, and specialized courses are generally set by schools themselves.
Question 2: which specialized courses to study and what reference books are there. It can be found from NTU Graduate Admissions Institute, which also contains information such as the number of applicants and admissions each year.
Question 3: You can ask students questions about textbooks. In fact, NTU College publishes reference books for postgraduate entrance examination every year, so it is good to use them. There is a shop specializing in buying second-hand books in Nantah headquarters. You can ask!
Finally, good luck to the landlord! Be admitted to an ideal school!
