The Future of Self-taught Examination: I'm glad to answer your question: Seriously, in this society, ability is the most important now, so self-taught examination is still a good choice, because self-taught examination requires an examination by yourself, and only those who have passed all courses can have a diploma and apply for a bachelor's degree certificate, so if a person gets a self-taught undergraduate certificate, it means that his professional knowledge is very good, which is very important in foreign companies. So it's better to take the exam by yourself. You can continue to ask questions, hehe … If you are satisfied, please adopt it, thank you!
