Distance education courses from conventional universities

The image shows for boxes connected through arrows.
In the top left corner the box reads "The University - Faculty, Courses, Lecturers, Students". Adjacent to the right of it is a smaller box "distance education department". From the first box an arrow points to this latter box reading "adaptation by consultants".
From "distance education department" an arrow reading "tutoring by consultants" points downwards to the box "distance education students". From this box an arrow points left towards the box "examination subsystem" in the bottom left part of the picture. The circle is closed through an arrow pointing from "University..." at the top-left downward to "examination..." at the bottom-left.
