Supplementary Answer: First, you need to understand a concept called "correspondence education." It is a way of teaching after being admitted through the adult college entrance examination. Correspondence learning means that the school sends you the textbooks, and you study through self-reading, TV lectures, computers, etc. Your communication with teachers is done via correspondence or email, and homework is also submitted through mail or email. Sometimes there will be a few days of face-to-face teaching and exams, and passing the exam will allow you to obtain the corresponding certificate. This is self-study, without face-to-face teaching. Correspondence education is proposed relative to face-to-face education, mainly targeting on-duty workers or students who cannot leave their work or study positions. Teaching is mainly self-study, with face-to-face teaching as a supplement. Students enroll through mail, and the school sends textbooks and other tutoring materials to students by mail. Teachers and students communicate through letters, allowing students to complete their studies without affecting their work or study. Correspondence: After being admitted by a university through the national unified adult college entrance examination, courses for the corresponding major are usually offered within three years, and classes are held on weekends or during winter and summer vacations, with teacher guidance in learning. Then the course teacher sets exam questions, and passing allows you to graduate. Generally speaking, as long as you pass the adult college entrance examination, graduation is relatively simple. There are two other forms of adult education: full-time and part-time. Full-time means attending classes from Monday to Friday all day, just like regular college students. Part-time refers to weekend classes or what we call night school. Second, generally, the lowest academic qualification obtained through correspondence is a junior college degree, and the highest is a bachelor's degree. Third, the academic qualifications obtained through correspondence are ordinary higher education academic qualifications for adults, and those who meet the conditions of the recruiting institution can take the postgraduate entrance examination. Fourth, if you have obtained a junior college degree through correspondence and want to pursue a bachelor's degree, there are two ways: continue to participate in the adult college entrance examination and apply for a bachelor's degree; participate in the self-study examination and apply for a bachelor's degree. Below are the differences between the adult college entrance examination and the self-study examination: 1. Different costs. Self-examination costs about 2000-3000 yuan at most. The adult college entrance examination charges tuition fees annually, with each academic year costing 5000-6000 yuan or more. 2. Different organizers: Each university has a corresponding adult education college or continuing education college, so the organizer of adult education is generally the state, but currently, some adult education is organized by social forces. The organizer of self-examination is generally individuals or private institutions, and some are organized by universities, but they are usually just using the university's name. 3. Different recruitment targets: The recruitment targets of our country's adult education are mainly on-the-job personnel and unemployed people, those who have left formal schools, and professional technicians and managers who have received higher education, which shows that it is truly adult education. However, there is now some flexibility, and more and more high school graduates are joining the ranks of adult education. The situation of self-examination is similar to that of the adult college entrance examination. 4. Different diplomas: The diploma of the adult college entrance examination is issued by the adult education college of each university. If you are admitted to the adult education program of a certain university, your diploma will bear the seal of that university upon graduation; the diploma of self-examination bears two seals, one from the main examining institution and the other from the local self-examination committee. For example, in Beijing, if you study accounting through self-examination, regardless of which school you attend, your diploma will bear the seal of Renmin University of China (main examining institution) and the Beijing Self-examination Committee, and there is no necessary connection with the school you attend; both self-examination and adult education offer bachelor's degrees, and those who meet the conditions can be granted a bachelor's degree by the state. 5. Different examination methods and difficulties: The adult college entrance examination is called "strict entry, easy exit." Students can only enter after passing the national unified adult college entrance examination. Just like the college entrance examination, you also need to fill out volunteer forms. But as long as you pass the exam, graduation is generally not too difficult (this is similar to general higher education); self-examination and academic qualification examinations are called "easy entry, strict exit." Students do not need to pass an exam to enter and can start directly, but if you want to obtain a nationally recognized diploma, you must pass each subject set by the state. The difference is that all subjects of self-examination are set by the state, making it the most difficult. 6. Different learning methods: The adult college entrance examination offers the most learning methods: there is full-time study, night school, correspondence education, and even early TV universities are a form of adult education. This gives learners a lot of autonomy: if you have sufficient energy and financial resources, you can choose full-time study and experience real university life; if you are working while wanting to improve yourself, you can choose night school; if you want to attend a famous university elsewhere, you can study without leaving home—through correspondence. In contrast, self-examination offers fewer learning methods, allowing you to choose between full-time study and part-time self-study (of course, larger cities may also have part-time self-examination tutoring classes). 7. Different value: If you must compare the two, self-examination generally has the highest value. 8. Please remember, the certificates obtained through correspondence depend on the nature of the institution and whether the certificate information can be found on the Ministry of Education's website. Only certificates that can be queried on the Ministry of Education's website are recognized by the state; otherwise, the certificate can only be used as a general learning proof in society and cannot be considered as academic qualifications.
