On-the-job study of the entrance examination for master of education degree consists of five subjects: pedagogy, psychology, political theory, specialized courses and foreign languages (English, Japanese and Russian).
Pedagogy, psychology and foreign languages are subject to the national joint examination, unified proposition and unified examination. Specialized courses are proposed by the enrollment units themselves and are carried out simultaneously with the national entrance examination. Political theory shall be organized separately by the admissions unit.
I suggest you buy some of Beijing Normal University's own postgraduate counseling materials. The stupidest way is to buy it at the copy shop of Beijing Normal University. Usually someone will print it out and they will file it.
I hope you go to your favorite school.
