Of course, the test is very difficult, not to mention the difficulty of the content. Even the all-English topic is a strong test of English level.

This certificate has a high gold content, which should not be particularly high in China, although it is said that capable college students have also passed the exam.

But after all, it is a minority, and the registration fee for the exam is also very expensive, which can be found in the CDCS examination area of Tian Hui Forum.
