Is it true that there is a Chinese education self-study exam opposite Zhengzhou University?

No, it's a fraud agency. I suggest you find the correspondence station of the School of Continuing Education of xx University. If you take the self-study exam, you will pay more attention to the official account of WeChat, and there will be a push. Information and things 100, registration fee 15 (taking Henan as an example). There are also classes, and even some apps are better than this institution. The institution will charge seven or eight hundred ordinary subjects for eight or nine thousand.
