Your ability to add and change coursework and settings in a course or section depend on whether you created the parent course and the child sections in it, or if you were only added to a child section as an instructor. The chart below will help you understand what you can and cannot do.
Parent Course Instructor= the person who created/ set up the original parent course
Child Section Instructor= the instructors who lead the individual sections
Note: if the 'Grading' settings are changed at the parent course level, they will take effect at the child section level. If these changes are made after students have worked in any section of the course, any recorded grades will be automatically and retroactively updated to be in line with the new grading settings.
