Sixth form central/south London

[MissMiaow]

I have a very bright daughter who is currently at a top girls state school. She is about to enter year 11 and is predicted to do well in her GCSE.
She does not want to stay at her current school for A level. She has been very unhappy there with friendship issues. She wants to go to a co ed sixth form and preferably not religious. Although clever she needs motivation to do well and I am struggling to identify schools /colleges for her to move on to. Any recommendations???

Harris Westminster, Pimlico, Greycoats (mixed in sixth), Graveney, or Kings Maths School if she is a real mathmo.

Note the first three are part of a consortium so share some classes.

Agree that King's Maths School is great, but they only offer Maths, Further Maths, Physics and either Economics or Computer Science at AS.

She wants to study psychology Biology and Art at A level.
