The problem

If you have several questions inside a single exercise, the display does not feel very nice for students that have only answered a subset of the questions so far: missing questions are displayed in red as "wrong".

Wanted solution

It would be nice if the grader could detect that the question is not "wrong" but "missing", and display it in a more neutral style (gray ?) in the report.

Considered alternatives

It is possible to use different exercises for each question, but not so pleasant. This is what @smdsousa does to avoid the issue.
