2. Basis for choosing a major for cross-examination:

First, look at your own interests, because interest is the driving force of learning.

The second is to look at the difficulty of self-study, otherwise it is useless to get online.

3. I suggest you choose a university you like, and then go to official website to check the professional catalogue of graduate students, and learn about the majors you may be interested in and may be admitted. The key to cross-examination is to choose a suitable school.

4. If you are interested, you can apply for the exam across majors, but you must prepare for the exam as soon as possible. After all, you can take the exam and see the scores. But as long as you prepare carefully as soon as possible, I believe there is a way where there is a will. Work hard.
