Students are allowed to take more than one section of the same course at the same time.
When a student takes more than one section of a course, all of their grades appear together on the report card.

Report cards will group all sections of the same course under one heading. If students are taking multiple sections of a course, and those sections must appear separately on the report card, the best practice would be to create multiple courses, rather than having students enroll in different sections of the same course.
