We are in exactly the same situation. My eldest son got about the same score as yours and was nowhere near
getting into Camp Hill, the King Edwards grammar closest to us. The school he was allocated (all our choices seeming to have been ignored) was Kings Heath Boys, which I am too frightened to send him to.
So we are going to live on baked beans and he's going to private school until we can move to somewhere with better schools. Australia is my current plan
My friend is currently trying to get her son into a better Comp than the one her boy was allocated, as he didn't get a place at Camp Hill either and she has moved closer to the school she wants.
We thought about appealling, but there was such a huge gap between his score and those of the children who got places, that it seemed pointless. The whole episode has been horribly stressful for him and I didn't want my little boy to be dissappointed any more.
I wish the little toad could have done the test now, as he seems to be doing so well at school and has just told me he got a level 5 in a sats practice for his comprehension, which was his weakest area by miles. But it isn't to be and he can be an Australian surfer instead
