Roles and permissions

Hi all,

i am using moodle 1.9.3 and 1.9.6.

In a course there are 3 groups and each group has one non editing teacher.

i dont wont to allow non editing teacher to see the grades of other group students.


i 've overriden the permissions- (given prohibit in override permissions - non editing teacher)
Manage groupsmoodle/course:managegroups and
Access all groupsmoodle/site:accessallgroups
but still non editable teacher can view other students grade(of other groups)

Regards,
