When is the calligraphy grade exam? How many times a year? Is there a test center in Hangzhou? What are the requirements?

Hangzhou China Academy of Fine Arts, Zhejiang University and Hangzhou Normal University once a year, probably one month after the Lunar New Year, right? There is Lanting next to Hangzhou, which is a little late, and then Jinan University didn't ask for registration before taking the exam. Lanting and Zhejiang University students don't accept it.
