Incorrect value when downloading attempts summary as CSV #367
Description
In one of my exams, a student got 11.2222222 out of 15 marks. When I downloaded the CSV the score is recorded as 14.2222222. All of the other values are correct, there is just this one incorrect value.
On looking further it seems to be part (e) of this question which is causing an error: https://numbas.mathcentre.ac.uk/question/122009/simultaneous-equations-with-3-unknowns-for-exam/
The student got all three gaps wrong and these were marked as zero on the attempt, but have each been graded 1 on the export. I can also see this on the change marks screen, although I did not use that to change any of the marks.
