Donghua University undergraduates need to take CET-4 for graduation. In principle, failing CET-4 does not affect graduation, but many schools require undergraduates to pass CET-4 before they can successfully get their diplomas. Of course, some schools don't require CET-4 or just cross the line drawn by the school itself to get the diploma smoothly. You can go to the student affairs office or the seniors to ask if your school must pass Band 4 before you can graduate.
