Make-up exams are generally not too difficult, but they also depend on the subjects. If the subject you fail is not the key subject of your major, it is quite easy to think about it. If it is the core course of your major, you still have to work hard.
You don't have to ask if you make up the exam again. If you still fail in any subject when you graduate, but you don't have a degree certificate from our school, so should other schools. By then, your university will be basically white.
