Highgate school for girls vs city of london for girls

[Aa78]

Any views on these two compratively speaking?

There's a Highgate School if that's the one you mean? It's co-ed.
Depends on whether you want single sex. CLSG's results are considerably better as well. Given the choice, I would always go for them. However, lots of competition for both schools. City (not sure about Highgate) have past papers on their website.

It’s not a straight forward question with one answer that fits all.
Depends on so many things.
Starting with simple logistics. Age of the kid. Etc.
And ending with the kind of girl you have.

Some would do better in Highgate. Others - at City.

Highgate is co-ed or do you mean Channing? In any case the schools are quite different so really depends on the girl.
