Thanks for the congrats on the remark. DS was similarly nonplussed about it Kingscote, they really have moved on.
But actually, I do think it’s important for a couple of reasons. Firstly they should ALL get the results they deserve and sloppy marking shouldn’t rob them of their rightful grade (and this was a science, so subjectivity can’t be blamed. The mark schemes are so prescriptive that even I, with no science background at all, can mark past papers, and I could see at least 2 glaring errors on the marking of one of DS’s papers submitted for review even without the benefit of the mark scheme.)
And secondly, there are some universities (eg definitely Oxford and I suspect Durham) who place a lot of importance on GCSE grades for some subjects, probably more so since AS Levels have gone. Quite rightly, given the advantages smaller classes, a full teaching staff etc confer, they expect high grades from DC at selective independent schools and look at the performance of an applicant vs their peers. At the moment DS has no intention of applying for Oxford (he’s seen how hard his sister works 
) but it looks like he’ll be going for a course and universities which have high entry requirements, so that erroneous grade could have made a difference.
And Brainmelt I agree it’s maddening that there are DC who will never know that they actually achieved a higher grade than they were awarded.
Sandy hope your DS had a good night and didn’t keep you up too late. I still can’t go to bed till I know that DS is safely in (although I do tend to fall asleep on the sofa and he wakes me when he gets back!)
whistl it’s so good to hear that your DS is flourishing at his new college. They all find their place eventually but it’s so hard to watch them struggle to get there.
