Self-taught college entrance examination is the most difficult way from university to university. The self-taught college entrance examination is a national examination, and it is all a test. It's the same all over the country, not which school, but which teacher gave the question. Unlike the general college entrance examination, teachers in the province usually write their own questions. Before the exam every year, schools or social counseling institutions lead students to review, tell them the key points and exam contents, and even tell them some exam contents. Students can pass the exam in the first half of the year. Whether it is the school, the students themselves or a responsible formal counseling institution, they hope that students will pass the exam, otherwise it will affect the employment rate of school students and their future. Self-taught examination is not only a question bank, but also generally no one gives lectures, reviews and focuses. More importantly, there are many self-taught courses, whether it is theoretical examination, practical course or graduation thesis. As long as you fail one course, you won't get a diploma, which is very difficult (of course, there is no limit to the number of make-up exams). Therefore, although many people have applied for self-study exams and passed many courses, they often fail to get diplomas because of individual courses. When they are busy after work, they don't care. Many people have to take the exam for many years and can't get a diploma. In addition, they don't understand many policy links. Many people have to give up the self-study exam halfway.
