In the past six years-1977, college students were students of workers, peasants and soldiers and were recommended to go to college. These students are generally radical and generally perform well. Although they have less cultural knowledge, relatively healthy political thoughts and stronger professional ability and quality than ordinary employees, their professional quality is lower than that of college graduates who resumed the college entrance examination. Finally, most of these college students were replaced by later college students! The country also recognizes their academic qualifications, and some people with strong self-study ability will also improve their quality and obtain new academic qualifications through correspondence courses at Night University.
