In the Course Group Requirement settings, I can note the requirement value, but an option to set a maximum number of courses does not exist.
To improve open-enrollment, it would be helpful to be able to prevent students from registering for courses that exceed the degree requirements. As an example, we had a student who was able to enroll himself in a seventh elective, although the requirement for his degree is only six.
The ability to place a limit on the number of courses required in a course group would benefit us.
