Hi I went to CSG and it is a really good school, the catchment area is small from what I can remember it didn't go further than the the top of Kentish town/lower Highgate if you know where I mean. Parliament and CSG are very different schools in terms of attitude towards learning and atmosphere I really enjoyed my time at Camden its worth the push or area compromise in my opinion.
The catchment for CSG is pretty small, I'm not sure you'd manage in N19.
It's been a while since I lived in the area so any info I could give on Parliament Hill would be very out of date - others to potentially consider would be Acland Burghley/La Sainte Union? (LSU Catholic)
I am about to move to Highgate n19. I have an 11 yr old daughter just started yr 7 but we have to move! What is the likelihood/unlikelihood of getting a place at CSG? Is Parliament hill as good? Also any thoughts on Elizabeth Garret Anderson school? Thanks!
