For example, the open education of China Central Radio and TV University implements a flexible academic system. After students at all levels take the fifth semester exam, the provincial power-saving organization will mark papers, make statistical scores and re-examine, and then review whether the students who graduated in the current period meet the graduation conditions, and then submit them to the Central Radio and TV University for review. It takes some time to save electricity, grade, check and audit, and then go to the Central Radio and Television University for audit according to the unified arrangement of the Central Radio and Television University, and then the Central Radio and Television University will feed back the audit results to TV universities at all levels for proofreading. After the audit by CCTV, please ask the Ministry of Education to assign the electronic registration number of graduates, print the graduation certificate, and then send the graduation certificate to TV universities at all levels in turn. The whole process, strict and serious, takes some time. However, once a student has finished his studies and passed all the subjects, the graduation time is determined.
