If you fail in the exam, you can only make up the exam. Otherwise, the credits are not enough, and you can't get a diploma after graduation. Generally, after failing a college course, there are plans to make-up exams several times, several times during college and once after graduation. You should make up the exam as much as possible in college and pass it. Otherwise you can't graduate. You can only go to school to make up the exam in 10 of the graduation year. That's just the last chance. If you fail, you don't even have a diploma. Four years in college will be a waste of time.
And even if you pass, you will be a few months later than your classmates. You have gone to work, and you are still worried about your diploma, which is very annoying.
As for the degree of difficulty, I can tell you that it is definitely much easier than the usual exam. After all, the teacher also wants you to pass.
However, even if it is easy, we should review it carefully to ensure that it is passed at one time. Come on.
