Admission to online education generally requires an examination, and unless it meets the relevant regulations, it can be exempted from examination. Colleges and universities recruit students independently and take exams independently. Colleges and universities will arrange entrance examinations according to their own training requirements and teaching conditions. But this kind of exam is a level exam, not a merit-based exam. Mainly to understand students' basic knowledge and learning ability, so as to ensure that students can adapt to the requirements of their major after entering school, and also to understand students' learning ability with the help of network and multimedia, so as to help students learn in a targeted manner. Most schools adopt the examination strategy of "lenient entry and strict exit". As long as they meet the basic learning conditions, it won't be too difficult to enter school.

Distance education, also known as online education in some documents issued by the Ministry of Education, is a kind of adult education qualifications. It refers to the teaching mode using TV, Internet and other media, which breaks through the boundaries of time and space and is different from the traditional teaching mode of staying in school. Students who use this teaching mode are usually amateurs. Because you don't need to go to a specific place to attend classes, you can attend classes anytime and anywhere. Students can also learn from each other through various channels, such as TV broadcast, internet, special counseling hotline, class research club and face-to-face teaching (correspondence). It is a new concept after modern information technology is applied to education, that is, education by using network technology and environment. Enrollment targets are not limited by age and previous academic qualifications, which provides opportunities for people who have entered the society to improve their academic qualifications.
