Um ... I haven't studied this. I'm not sure. However, you should go to the website of the school you want to enter and look for the recruitment information of graduate students. Some schools have designated examination materials, while others don't. You can go to the forum or find your classmates in that school, ask the seniors and sisters who took the exam in that school before, and ask what books to use. Every school is different, and professional courses are generally given by our own school.
