Does the subject want to ask, "There are more credits after the required courses in the university are rebuilt than before. Is the course replacement calculated according to the original credits or the current credits?" Now According to the website of the Ministry of Education of China, the courses re-taken by the university are duplicated with the courses passed before, and the credits of this course are usually counted repeatedly. In-school courses are replaced by specific courses and credits in the training program, and courses can replace corresponding courses in the professional training program. The excess credits are recorded in the total credits of students, so the course replacement is calculated as re-taking credits. The number of retakes of the same course shall not exceed a certain number, otherwise the credits of this course will no longer be calculated.
