Hi Martin,
It was thinking if it is not possible to make a counting of time for the quiz, being been that, when it finished the time that is defined by the professor the page would save the answers of the pupil and came back toward the page of the agenda. Ooutra thing would be the estatistica of entrance and saida of the pupil in moodle it was computed and shown in the grating.
In more I continue developing the manual and divulging the Moodle idea.
Been thankful
