#31 marking status reported incorrectly

[Neil Strickland]

The quiz review page reports all attempts that a student
made at a particular question, whether each attempt
was valid, and whether the student asked for each
attempt to be marked (or merely validated). In some
circumstances, the page reports that the student asked
for an attempt to be marked, when in fact they did not.
(I think this only ever happens for the most recent
attempt, but I am not sure about that.) In these cases,
the overall mark for the question is also reported
incorrectly on the review page, as is the total mark for
the quiz. On the other hand, all marks appear to be
reported correctly on the quiz page seen by the
student, and also on admin pages that show results for
all students.
