How long is "long"? Is nine questions "long"?

Nine questions didn't seem too long when I made the quiz but now it seems a bit much. Mostly because I just graded 7 more.

Since a Moodle quiz tend to be graded in percentages, it might be good if the number of questions was a nice factor of 100. Like 1, 2, 4, 5, or 10, for example.

i should make my long 9 question quiz longer?!

It might not matter, since all of you students seem to score 100% on every quiz they complete.

well its more of participation. i grade and give the points. some are wrong but the main thing I am looking for is the doing and the trying.
