We are moving to Bucks as we want our DS to attend a grammar school. We found that some areas (postcodes) cover up to several schools while others cover one or two. For example, a postcode in East Amersham (towards Little Chalfont) will cover only Dr Challoner and Chesham Grammar, while those West will cover RGS and JHG. Are we correct in this analysis, any views or recent experience, as it seems it has all changed past year or so?
