The registration of CET-4 and CET-6 is also competitive, and the number of places is limited. Many students in many universities have not applied for the exam. Although the number of applicants has increased year by year in recent years, I have never heard of any student who failed to apply for the exam, only those who missed the exam. It's not that the school deliberately restricted it and failed to catch it. CET-4 and CET-6 are national examinations, and there must be a standardized examination room that meets the specifications and is equipped with a perfect video monitoring system. No classroom is used as an examination room, so there are limited classrooms in the examination room and there are not enough examination places.

In addition, there are some people who don't pay attention to CET-4 and CET-6 at first, and fail to pass the exam again and again. Missing the exam will occupy public resources.

CET-4 and CET-6 certificates play an important role in job hunting and continuing education.
