Only children who live in Bucks and qualify are guaranteed a GS place but not necessarily their nearest.
Many children qualify from out of area and do not get a place.
Thank you Guest55 for your response. I wanted to know how literal 'guaranteed' a GS place is in Bucks as it has been said a number of time on Bucks forum. From what I've learnt so far, it's actually not guaranteed but best endeavours (from speaking with Bucks admissions).
Sally-anne was able to provide the answer what I was looking for, so thank you Sally-anne. Very informative as always.
And it looks like I need to move within 3miles of SWB to stand a chance of getting in!!
