Postgraduate self-study examination is a form of part-time education, which allows individuals to continue to receive higher education under work or other constraints. Compared with the traditional full-time postgraduate education, this method is more flexible, and there is no need to leave your job or stay in the school for a long time. By arranging time independently, choosing suitable study materials, and taking the entrance examination recognized by the state, you can get a master's or doctoral degree after meeting certain requirements.
