Part-time graduate students majoring in mathematics. According to relevant public information, universities offer part-time postgraduate courses in mathematics, which are suitable for people with professional background in mathematics or related work experience. They need to continue studying or improve their skills, so they can't attend full-time study. Part-time postgraduate courses usually arrange more flexible study schedules to meet students' work and other obligations. Part-time graduate students pass the national unified entrance examination for graduate students, and then go to the re-examination organized by colleges and universities themselves. After passing the national unified examination and re-examination in colleges and universities, they are admitted to colleges and universities or other institutions of higher education with the qualification to implement postgraduate education, which belongs to the elimination and selection system of ordinary higher education and gives priority to admission.
