sometimes results should not be visible directly to the other, but on a certain time all together.
in the assessment form and the the overview of a course element in the assessment tool, in can be decided, if the result is directly visible or if it not yet visible.
by default all results are directly visible, expect a test with manual correction. the eye symbol (fa-eye-slash) visualizes the users, where the result is not yet visible.
If the "Set to 'done' status" is chosen, the status changes to assessed and does not have any impact on the visibilty
