In fact, it is not difficult to take the unified examination at the initial examination. As long as you review carefully, there will be no big problems. High marks are king.

Every school is different in the second interview, but you will definitely ask questions related to your major. However, you will know some basic knowledge of pedagogy in the process of preparing for the preliminary examination, and the rest depends on you to read more professional books under your major and understand the cutting-edge trends, especially the papers and works of professors related to your school before the second examination. Often the questions related to your major in the second interview come from these places.

I can't give you a more specific answer because your question is too general and you don't know which school you want to go to. You'd better judge according to the school you want to apply for.

In addition, I suggest you go to the forum of the school you want to apply for, and find out whether there is any information about the past few years and whether there are people who have been admitted, which will help you communicate with them.

I hope I can help you.
