When you request a combined course, you also designate one of those sections to be the primary (PRIM) course. Requests for combined courses are completed immediately; the primary course is designated with PRIM in the course name.
Student rosters from My麻豆精品 will be automatically populated into the primary course from all related sections. Drops and additions will be automatically maintained in the primary section with daily feeds from My麻豆精品.
You will find that all sections will appear in your Blackboard course list. You only need to add new content to the primary course and make only the primary course available to students.
