I graduated from primary education (mathematics) and want to take the postgraduate entrance examination. Will my academic qualifications change after the postgraduate entrance examination? Is it easy to find a job in the future? Can I teach math in junior high school or senior high school? Now I have a bachelor's degree, and it is relatively easy to find a master's degree after graduation. Some undergraduates I know can teach high school mathematics after graduation. However, even if you graduate with a master's degree, you should only be able to teach more and more high school doctors, and the level of teachers required for undergraduate courses will be improved accordingly. Even after graduating from a master's degree, it is difficult to teach in three universities.
