Online education is an independent enrollment and examination for colleges and universities, and 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. In addition, if you meet the relevant regulations, you can also enter the school without examination. Those who do not have the exemption conditions need to take the entrance examination organized by the network college. The test sites are all registered in the learning center, which is generally an online computer test. The subjects of the senior high school entrance examination are Chinese, mathematics and English.
