Wallington high school for girls catchment

[AAAY]

Hi
I think I may just be slightly out of catchment for WGHS and struggling to find any websites which can show me exactly 6.7km from my address. I cant check the sutton catchment calculator as we live in Mitcham bordering Tooting.
Does anyone know of any girls that have been given places in the Mitcham area? trying to avoid a move as although WHSG would suit my DD1 there is no guarantee she will get in even whilst being in catchment and also it is very unlikely that DD2 would be suited to this school so im hoping to stay where we are so that both DD's have options but also be in the catchment for WHSG. I know I'm trying to tick a lot of boxes here!
I have emailed the school, unfortunately its half term and not sure how much they would be able to tell me so hopefully looking for some confirmation from any WHSG parents.
Thanks x

If it's your true first preference, then put it first. Your DD will either get a place, or she won't and she'll be on (or at least, be able to go on, whatever the system is for the sxhool) the waiting list. Ditto your second, third, fourth, fifth preference (hopefully you will put your 'banker' school at least as your sixth).

Consider Carshalton Girls as well. More likely to get in to that school as not grammar/based on exam score.
