Whenever we have MOCK exams, we make a copy of the actual timetable and in that copy I have to remove all lessons from a year group.
Normally I use the subject timetables, but still it takes too much time, going subject by subject to delete those lessons. If it is by pupil it would take me even longer.
That's why I was wondering if it would be possible to have a view year group timetable in a development timetable.
