Had some difficulty signing in, so late to this. I would like to say, that whatever happens, I do think that the most important thing is to be positive about the school.
Obviously it's important to appeal on travel grounds, and indeed some local authorities appear quite mad in their allocations - we could write a book on the idiocies. I had friend whose son was allocated a place similar to gillybob's, but (of course) there is no public transport for evening events, and my friend does not drive (and can't afford a car).They thought it quite reasonable that any parents' evening / school performance should entail a parent on minimum wage paying £20 for a taxi.
But, whilst appealing, I really do think everyone around the child needs to be positive about the school itself. All of my kids went to their local comp, shunned by some parents. Their colonisation of the 'good' school across the border was part of the reason my friend's son couldn't get in to his local school - why take the rather average child of a poor parent when you can get affluent ones driving their children in and contributing to whatever fund you want to name.
I noticed a huge difference in the kids who regarded their school as something inferior - 'if only they had got into the posh school, they would have got better grades, been able to enter a profession etc.' and those who got on with their work, got on with the kids around them and made the most of what was offered.
