Professors teaching more than one section of the same course may choose to have a meta-course created to simplify the management of duplicate and cross listed courses.
Once you have requested your meta-course (see Moodle Help Form) and received confirmation it has been created, you will need to add your courses to that meta-course.
From within your meta-course, in the Administration block click Users to expand that section and click Enrolment methods
On the Enrolment methods page, from the drop down under Add method, select Course meta link
On the Course meta link page, from the drop down next to Link course choose the course you'd like to add to the meta-course and click Add method.
You will repeat this process for each course you'd like to add to the meta course.
