My ds is really disappointed with his results. His target was 8, he was regularly achieving 7s in mock etc, put in a lot of revision over Easter and came out with a 5. He can't understand what happened and nor can I! School have advised he is right on the boundary (i.e. just squeaked a 5) so are advising against a remark although they will get the paper back. I'm sure enough that something has gone wrong to wonder if a clerical check would be worth it just in case there was a processing mistake? Does anyone has experience with this?
