Why don't you give advice on how to win appeals?
I do provide some general advice, but (a) So often appeals need to be targeted towards specific schools (b) I am in business to supply such advice. I choose to run this website in addition as a support for parents. There is plenty of general advice on websites such as elevenplusexams (I am happy to refer to them, but they won't mention me, as they make money out of recommending other sites). The website is very much biased towards Buckinghamshire grammar schools where the appeals system is very different, so be cautious about the advice offered. In particular, the Kent Regional Advice page remains factually very wrong, in spite of my protestations that they must change it.
