Steps

• As a teacher or administrator, go to the homepage of the course.
• Click on "Settings ..." from the block "Administration" if the course has been created and has no student enrolled or creating a new course.
• Go to drop down "Is this a meta course?" And select Yes
• Since the course set up, click Administration> Students.
• Use the form to add the course or courses at your meta course (tuition will be imported).

Important

If a course is a meta course, the Administration> Students change the listing or looking for students to list or search for courses.

Must not have any student enrolled as a meta course to enable it. 
If a new student enrolled or unenrolled a student from a course father will automatically be enrolled or unenrolled from the meta course. 

Suggestions

Allows creation of a course that is subordinate to others, eg a common area of different courses that require another course but all students in other courses.
