Freshman failed the make-up exam last semester.
Study hard during the holidays, memorize the key points and exercises that the teacher said in class, buy relevant materials, especially go to the copy shop around the school or review the materials with high scores. Don't cheat in the exam. Once caught, you will basically be expelled from school or cancel your degree.
Make-up exams are more difficult than normal final exams, because there are no usual grades. If you haven't passed the exam, you have to retake it, and take it with your juniors until you have passed it, even within 2 years after graduation.
Study hard in the future, the university is mainly self-study, laying the foundation for independent study after graduation. The most important thing for universities is to cultivate the ability of autonomous learning and lifelong learning. If they don't adapt, they will be eliminated in the future society.
