I am very sorry to hear about the disappointing result. If you feel you have enough evidence of academic ability / mitigating circumstances you can have a go at appealing. Have a read of the following:http://www.elevenplusexams.co.uk/forum/11plus/viewtopic.php?t=8255
Do you happend to know of his score / rank results ? - this may give you some idea about how far away he was from passing. Obviously you tend to have more succwess at appeals if you are fairly near the pass marks / marks of last child admitted.
Thanks for your advise , I have read the link .
The problem is that his results were very poor 277 weighted score , when absolute min for grammar school is 303. His percentage scored worked out at 43% , and his regular average is 80% for the last year with school and 90% with tutor.
This is one of the main reason its so shocking and unbelieveable , thts why we know something is definetly not right.
