1, junior math major, math is not very good, I want to take the postgraduate entrance examination. If you plan to be a high school math teacher in the future, it is better to take the subject teaching (math) research.

2. Subject teaching is a professional degree of Master of Education, which mainly trains middle school mathematics teachers.

The difficulty mainly depends on the reputation of the school and the city where it is located, because the applicants are different. If it is a major, it is not too difficult to apply for subject teaching.
