Generally speaking, it is enough to pass the college exam. The make-up exam is set by the school for students who fail the final exam, and they cannot apply on their own initiative. If you fail in the make-up exam, you must take it again. You need to pay extra to attend classes with the next class. Make-up exams and retakes will be recorded in personal files (some schools don't remember it, which is wrong), and the severity depends on the situation, because when looking for a job, some manufacturers won't care if you take the exam or not.
