You must pass the make-up exam, but you won't graduate, but schools generally don't embarrass you because they also want the employment rate of students. Regarding the difficulty of the make-up exam, you can contact the teacher who gave you the paper or the teacher who taught you this course before. Some well-meaning people will give you answers and give you the scope of the question, and you can pass it by rote. Mainly depends on the strict management of the school. Some schools will be more relaxed when marking papers. As long as you fill in the paper and work hard, it is said that the make-up exam is the time to release water, but it is best not to cheat. If you catch it, it will be really difficult to graduate. Anyway, review well. Come on.

By the way, if you are not satisfied with the credits, you will get credits for your graduation thesis.
