    004 * Course of a teaching request. If a course is marked as exclusive, all assignments of an instructor must have
    005 * the same course. It is also possible to mark the course as same common, which require all assignments that are
    006 * given to a single instructor to share the same common part of the course (e.g., the lecture).
