Re-taking courses can change the grade point, but it can be divided into two situations. The first premise is that there is no re-examination of failed courses. If the final grade is higher than before, the grade point will be higher. If the final grade is lower than before, the grade point will not change. The second is the second interview after failing the course. Since the re-examination, it means that there is no re-examination. After the re-examination, the final score of this course will be shown as the final score, and the record of failing this course will be left. Of course, in either case, there is a charge for reconstruction.
