It’s all the same.
The grading examination is only a third-party testing test to prove the staged results of learning music. The grading examination is the same no matter which school holds it. In a practical sense, the grading examination certificate has no gold content. Only music competitions on the whitelist have a certain gold content.
The national music grade examination is divided into two major categories: one is the special music performance skills examination for vocal music and instrumental music. The second is the basic music knowledge test.
