Failure to complete the minimum credit requirements in one semester (generally less than all credits in this semester) is a warning to drop out of school, and you will be ordered to drop out of school after three consecutive warnings. Generally, after two warnings, a teacher will advise you to fail, but you don't have to fail. At the beginning, the dean asked me to fail, saying that I couldn't keep up. I said I wouldn't repeat the grade, so I read it, no problem. The choice is in your own hands.
So in your case, all you have to do is take the failed course again, no problem. However, it should be noted that if you are already a graduating class, but you still fail this semester, you will be in danger if you don't take this course and make-up exams next semester, and you may have to take another semester or even a year.
