(Reference Mladen at support) After completing an assignment (acting as a timed quiz) where results and feedback are withheld, a yellow question mark appears by the assignment.
At the moment there is no way to have a completed green check if we don't want to show the result. Some students finds the yellow question mark confusing and the message "Progress Not Disclosed" jarring as they wondered if their submission went through.
I thought it would be better if we could have "Score not available" and a green check. Or at least change the message associated to a yellow question mark to the less shocking message "Results Withheld".
