Does South China Normal University authorize Shenzhen Pengzhong training institution to participate in the training of self-taught independent classes?
This has nothing to do with authorization or not. Authorized institutions can check in official website. You can check in official website, a university. They took the exam here when I taught myself before, and I chose South China Normal University. Now I have finished the exam and got my diploma. The head teacher in charge of us at that time was quite responsible.
