I don't think so. CET-4 and CET-6 are different from the certification level examinations in other countries. The theme of CET-4 and CET-6 is college students, and the normal procedure is to register through their institutions, so it will be convenient for them to take exams, pay fees, check their grades and get certificates. Generally, it is very simple to go through the school registration procedures. If you don't want to go back, you can ask your classmates to help you Just choose a Band 6 in the registration system (tell others the password first, and then change it when you go back), pay the registration fee of 17 yuan, and sign another name. Usually no one will verify who signed it. If you really can't, go back, because you have to register in other places, and it won't be much easier to get the certificate later than going back to school. I wish you good grades.
