DS is at Holland Park School in Year 10 and doesn't want to stay on for sixth form (the school has all sorts of problems although the new Head is beginning to turn it around). He is bright (already got 3 GCSEs at grade 9 and on course for 8 more top grades) and will want to apply to Oxbridge. With that in mind, we were thinking Harris Westminster or Tiffin? Chestnut Grove is also a lovely school - and less of a hot house! Any further suggestions would be most welcome. We live in SW11
