When the visible mode (Groups) is switched on, teachers are able to see the marks of students in other groups (though they can't see the submissions). I imagine this does the trick for people who use the grouping function to split up marking (no need to hide grades) but I'm using it to separate differnt schools (1 group = 1 school) who participate in a common course. I need to keep marks private (teacher only sees marks from her/his students. Has anyone created a work-around for this? Suggestions, anyone?
Thanks,
Fernando
