You can choose the time to retake classes in college and they will not be repeated.
If you fail a certain course in the university examination (usually a required course), you will need to retake the course in the next academic year and take the exam again, which is called retaking. Most colleges and universities adopt this strategy: when a student fails multiple subjects in the final exam, he or she will be given the opportunity to make up the exam in the first week of the next semester. If the student passes the failed subjects during the make-up exam, there is no need to Retake, but if you fail more than a certain number of subjects, you will have to retake these courses.
Or if you have not passed the subjects after four years, you need to retake them and pass the exam before graduation. A certain amount of repair fees will be charged for re-repair. There are two types of retakes: joining a class to retake the course and setting up a special retake course.
Types and application conditions for retaking elective courses
If you fail to retake all compulsory courses and professional elective courses and fail to obtain credits, you can apply for retaking them. All current students who are dissatisfied with the grades of courses they have taken, passed the exams, and received credits (except for general education courses, interdisciplinary elective courses, and practical courses) can apply for improvement and retake.
Basic requirements for retaking courses
Course selection time: Generally within 10 days of the start of the semester. The courses students apply to retake must be courses offered this semester (including group retakes), and the course credits and teaching requirements must be consistent with the requirements of the talent training plan for this major. The sum of the total number of credits for the courses a student applies to retake and the total number of credits for the courses being taken this semester shall not exceed 34.
