It's a good point about remarking, the chance of a lower mark that is.
I was one of the rare ones where DS's paper in VR gave a revised score (upwardly) by hand marking, although it was only a single question it gave 2 points higher in his standardised score. The LA are clear to state that all papers are marked in the same way so others may have equally had the odd question missed by the machine
All papers viewed by parents are currently hand marked, not sure if that extends to all appeals though if you don't want to see them prior to the hearing.
We also were able to view the questions at that time and I think this was something that KCC withdrew last year, as capers said there is no legal obligation for them to let you even see the multiple choice sheets and to be honest they now don't offer much information as it's essentially a list of boxes.....
