Yes, quality extension credit is also a kind of credit that must be obtained and must be completed according to regulations. However, it should be noted that this may be the easiest credit to obtain, which can be obtained by winning the prize in the patent thesis competition of social practice voluntary service, attending lectures, donating blood and so on. Please take a closer look at the relevant regulations in the student handbook and see if there are any students who meet the credit requirements but have not applied. Just complete the credit application as soon as possible. Judging from the actual operation process, I have never heard of such a case in which credit graduation is affected. I believe it should not be a problem.
In addition, it should be corrected: it is impossible for students to fail in the course but graduate, or they have already completed the re-examination, or they have reached the credit requirements of public elective courses by signing up for other courses.
