Ok, thanks, but then that begs the question and introduces the 'Catch-22' for me of:
If I make it that the 'of X' is the number of enrolled 'students' on the course that are eligible but may / may not see the quiz then the total will be correct, however the teacher will complain that 'they are missing some students' from the total and the missing students say 'but we can't see the quiz'.
I leave as is and you have this issue.
Alternatively, I don't publish 'Attempted' etc. if the module is not actually available. But then if I do that then completed and hidden from student activities
will not show this and the teachers will probably complain.
What's the real word answer to this?
