Many thanks Tim for trying to clarify the "insanely complicated" quiz module. I hope my remark will not make you insane, but will help clarify things further:
On the diagram you posted to the wiki, are "answer" and "response" actually the same object, namely "the student's answer" to the question? If different, what are they? If not, why not use the same term?
TIA,
Joseph

Oops yes.
One of the things I have come to appreciate in the quiz code I inherited from Gustav, was the fact that it is very consistent. The things entered by teachers when creating the question are answer. The things entered when students attempt the quiz are responses. Diagram fixed.
