Twyford CoE Sixth form in West London: strengths and weaknesses?

[ingok]

Hi, I would greatly appreciate comments and up to date feedback on Twyfords''s Sixth form. The school is rather large but has overall very good reputation and results but is the sixth form truly outstanding academically? What are the key strengths and weaknesses of the Sixth form? Is it a better school than Lady Margaret or Maryleborne which are smaller and have also excellent results? The head of sixth form recently left, is this a positive development? Many thanks.
