I don't know if you're talking about the self-study exam of Su Da or the self-study exam. If it's a student aid, it's run by Suzhou University, but half of it needs to take the national self-study exam, and the other half is given by Su Da himself. It's a little difficult, but you still have to rely on yourself. Your diploma is Suzhou University. If it is not a self-study exam, it is a big self-study exam in society, and it has nothing to do with Su Da. I think you should take a self-study exam. This diploma is valid all over the country. I took the English class in 2008. At present, there is no one in our class, and I am still struggling. . . .
The teacher's words are basically graduate students of Soviet University!
