I can only speak for me, but getting emails over a weekend giving out detailed plans on what the kids need to be doing on each subject, spending all day getting in emails of digital or scanned bits of paper to mark, then in the evening (and I mean literally every evening) sending out marks, scanned comments & corrections, then arranging calls with parents every week (outside of working hours) to go through progress & responding to emails pretty much at any time- all for each pupil- I think what they're doing is brilliant. If you aren't doing that then thats your call, but from what I see these people are properly going the 'extra mile' to make sure everyone gets what they need to keep making progress & get the right attention.
