Any subject is likely to fail. The investigation conditions of elective courses are not as high as those of compulsory courses. Generally, attendance rate and homework completion rate will be examined. If the check fails, the course will fail.
Failing a course is synonymous with failing or failing. Specifically, it means that one or more subjects fail the exam for various reasons and fail to meet the prescribed standards, which means that they need to retake or retake the exam.
