You need a certificate of reading music. Level 9 is enough. I am also a pipa student. Last year, I took an examination of the art specialty students in several universities. The first item is to play your own songs and prepare two songs, but the general teacher will not let you play them all. The second item is reading music, which can give you a piece of music to play fluently in a short time. I took the exams in Tsinghua, Beijing Jiaotong University and Beijing Institute of Technology, and I will give you a certificate after taking the exam in Tsinghua. A on the certificate can give you a chance to be admitted to other institutions and get lower scores, but I think it's no use taking too many exams. You can only fill in one when you volunteer. This is a good advantage. I think I didn't take the art major of Zhejiang University because Zhejiang is too far from my home, so it is very troublesome to take the exam. Come on, son, you're lucky.
