We try to move house and got a little bit overwhelmed by the admission criteria/ catchment area. I'm looking into different boroughs and somebody told me about "walk it" - eg google map, but now I've seen a map of Muswell Hill with lots of circles and I'm not sure anymore how I should roughly measure - one line from school to house or street by street? All the catchment areas seem to be so tiny, and I don't want to be left without school. Thanks for your help!
