does the decision depend on haw far are you off the final cut-off score ?
Generally speaking I would have thought that the further away you are from a qualifying score, the stronger your case would need to be - and the closer you are, the better.
I suggest you contact the clerk/administrator to raise your concerns - to see what response you get.
Alternatively you could write to the clerk/administrator requesting a copy of the clerk's notes, but be prepared for the fact that they may try to resist providing them. See:http://www.elevenplusexams.co.uk/11plus ... ers.php#d4
