First of all, let me explain that these should not be called self-study exams, but belong to the category of adult re-education. The Ministry of Education divides China's higher education into three categories: full-time, self-taught and adult higher education. First of all, what the state does not recognize is that as long as it meets the graduation certificate officially issued by the Ministry of Education, the state will recognize it. However, in some places, or in some fields, such as the recruitment of civil servants, such as the recruitment of some large state-owned enterprises and banks, it is usually divided into two types: full-time colleges and universities and state recognition, among which the above-mentioned categories mentioned by the landlord belong to the state recognition, which are not so hard compared with full-time brands. Secondly, the self-taught brand is hard. Then there is the adult college entrance examination (adult college entrance examination needs to take the national unified adult college entrance examination, and then you must attend classes at school). Other kinds are similar. In many places, the adult college entrance examination is similar to the general college entrance examination, especially the adult college entrance examination for technical majors you study is similar to full-time college entrance examination.
Secondly, explain the problem that you need time. The self-taught exam is generally about 14 subjects, and you can take 8 subjects every year. If you have the ability, it may be about a year and a half. But if it is an undergraduate course, it usually takes two and a half years from registration to getting a diploma. But the self-taught exam is true, and there is no fraud at all, because the topic is the Municipal Education Commission (the public subject is the Ministry of Education)
I wish the landlord success in his studies!
