I have set up a custom grading scale that has only two values for an assignment is turned in: needs revision and satisfactory.
I make feedback on this assignment automatically visible to the student in the topic module when the assignment is graded and they achieve a rating of satisfactory on the assignment.
Formerly, I was using a numerical grade and could set the feedback's restricted access to a point where they had received a certain numerical grade (get at least this grade and you can see the feedback).
I would like to now change that so that they can see the feedback once they get a mark of satisfactory. However, I only see the capability to restrict access with grades based on numerical values. How would you restrict access based on a non--numerical value?
