How about those authoritative training institutions, such as the Science and Technology Training Center of China Normal University, taking the self-taught examination in Guangdong?
I don't think any senior has answered so well. I also took the exam by myself, knowing that he spoke very well on the Internet. After signing up, they are just like intermediaries, just enrolling students. After signing up, they asked me to go to other places and say that I had to go through formalities, get books and get information. I really don't understand what this is.
