Each major takes the postgraduate entrance examination in English, and the mathematics department takes the postgraduate entrance examination. If you are still majoring in mathematics, then take four courses: politics, English, advanced algebra and mathematical analysis. If you take other majors, you will take politics, English, mathematics and specialized courses. As for employment, it depends on whether you study well or not. Students majoring in mathematics usually focus on programming or financial securities, but now they are quick in statistical analysis and data analysis. I am also a math major. Forty people in our class graduated and have been working for four years now. The average monthly salary of the whole class is about 12 thousand.
