Mathematics is not a compulsory course, only some science and engineering majors will take the exam, and calligraphy is definitely not.
The postgraduate entrance examination for calligraphy majors, like other majors, is divided into initial examination and second examination. The total score of the initial test is 500 points, including 100 points for two public courses (foreign language politics) and 150 points for two specialized courses. Professional courses for calligraphy majors generally take the general examination of fine arts and the history of calligraphy or fine arts in China. After passing the initial test, those who pass the results and rankings can enter the second test. There are still some colleges and universities that may try to test the theory of the first and second times, but in general, these are all the subjects. The specific medicine depends on the general arrangement of the college you apply for.
At present, there are many colleges and universities offering calligraphy majors. I will only say what I know: Beijing Normal University, where Qigong once taught, has a tradition in this major; The Capital Normal University, where Ouyang Zhongshi teaches, is also very traditional, and it is also the first doctoral calligraphy program in China. These two calligraphers should be regarded as the best calligraphers today. Secondly, there are some calligraphers such as Wang Yong in the Central Academy of Fine Arts.
Calligraphy major belongs to fine arts, and it is a subordinate discipline of fine arts, so the score line is also in accordance with fine arts. This year, the national total score is 320, the foreign language political minor score is 42, and the professional minor score is 68. You have to cross the line to qualify for a second interview. Beijing Normal University is one of the 34 independent marking institutions, and its score line will be higher than the national line. If your culture class is not strong, it will be more difficult to take the exam.
