The main reasons for the pass rate of the Yangyin Level 9 Card are the high difficulty of the exam and the high requirements for candidates.

The Yangyin Level 9 exam is more difficult, including multiple musical instrument performance requirements and complex music design. For many candidates, it is difficult to fully master the various skills and knowledge required for the exam, which affects their performance and results. The Central Music Level 9 exam requires candidates to have high musical literacy, expressiveness, and innovative abilities. It also puts forward higher requirements for candidates' musical theoretical foundation and comprehensive practical ability in the subject. This also makes it difficult for many candidates to achieve the required level in the exam.

In addition, as a high-level music examination, the number of participants in the Yangyin Level 9 exam is much smaller than that of other levels of exams, which also leads to a low pass rate.
