Southbank vs ISL

[HKinLondon]

We have found out very last minute that we are moving to London. My DD (Grade 10) has been accepted to both schools. My DS (Grade 8) has been accepted to ISL and is waitlisted for Southbank. I would appreciate any information that would help us make a decision on which school to select.

Hi OP, I only know of Southbank but I hope someone with kids at either school will come along to advise you.

I suppose my question would be where do you want to live? ISL is quite far out west (Chiswick) compared with Southbank. Do you feel strongly about this?

If your DS doesn't get into Southbank (and that is the one you go with for your DD), do you have a back up option? You don't have much time before the next term.

They are in two different parts of london. If your DS won't get place in southbank it would be hard to have DS and DD in these two schools purely from practical point.
I don't know much about ISL. southbank is considered to be a good school but they did have a scandal with paedophile teacher recently - you can google news.
