The National Open University cannot enroll full-time undergraduate students. The National Open University is an adult higher education institution, which mainly provides higher education for adults from all walks of life. Therefore, the National Open University does not provide full-time undergraduate education, but provides part-time undergraduate education (adult undergraduate education), that is, education and teaching activities are carried out for students with certain work experience and aged between 18 and 60.
