Submitting empty mathematical expression is considered "answered" #1093

Closed Spruce8913 closed 3 months ago

Minimal working example here

In a multipart question, students rely on the "Answered" or "Partially Answered" overview for the exam, to see what questions still need attention. When submitting an empty answer for a number entry, the part is marked as unanswered; when submitting an empty answer for a mathematical expression, the part is marked answered. image

Would it be possible to check for empty submissions of all part types, to make partially answered labels more reliable?

The difference isn't that part a is a mathematical expression part: it's because it's a gap-fill.

So gap-fill parts should not be marked "answered" if any of the gaps failed to be marked. (this is for me to fix)
