I have 1.9 and groups*. But when a new student register and have no group, when he finish a quiz all teachers receive the notification. It´s possible when a student without group finish a quiz only the admin or nobody receive that notification?
Because all teachers receive e-mail about a tudent that is not their group is borring...
*The way you could do it based on the 1.9 work is to use groups, and create lots of groups that just contain the student, and the parent or mentor. Then set the quiz to separate groups, and set the parent/mentor role to get email whenever someone in their group completes a quiz.
