Failing a compulsory subject at the University of Wu Han would affect the graduation certificate. According to the graduation requirements of the university, the compulsory courses had to meet certain requirements before the graduation certificate could be issued. If the results of the compulsory courses are not satisfactory, you may need to retake or retake the exam to meet the graduation requirements. However, it was important to note that if one failed a compulsory course, even if one achieved excellent results later, it would not make up for the previous failure.
