A merged course is a site in which multiple subjects are merged into one site. It is then possible to work in one site instead of having to manage student interactions and grading across multiple sites.
Merging copies the student enrollments from one or more "child" courses into a "parent" course. In the subject listing, Parent and Child subjects are displayed together. Content and teaching is managed from the parent site. After merging the child course will be unavailable.
After merging occurs, all enrolments in the child site are replicated in the parent site.
Students will not notice any difference when accessing the subject site. Students will have access to the subject outline for their particular cohort.
