You can always add/remove Course Sections from the Course Sections page after students have subscribed. However, after making changes you will need to check the following:
- from the Course Sections page, confirm that the correct Instructors/TAs are assigned to the sections. (If not, instructions are here).
- from the Course Sections page, confirm that all students are assigned to the correct sections. (If not, instructions are here.)
- from the Assignments page, confirm that the due dates are correct. (If not, instructions are here.)
