In fact, I don't think we should take any chances on this issue. Maybe you passed the exam and then felt that the invigilator was lax. If you fail, you may feel that the invigilator is very strict. Actually, strictness is relative. If the invigilator is a serious person, if he catches something and doesn't remember anything, it's hard to say without a degree certificate. But if the invigilator is a teacher, that's ok, but who knows how to invigilate? Therefore, some people want to take the side door, and if there is no problem, it will be fine. If there is a problem, they can't bear it. Whether you have courage or not depends on the individual. However, my friend, I still advise you to study hard. After all, it is very important to get a college degree certificate. Don't take any chances.
