No, I was just comparing exam results listed on individual school sites; a lot of schools withdrew from the league tables this year. Frankly at this level it doesn't make much difference, as all these highly selective schools do well, and I admit that exam results are just one (narrow) indication of the success of a school. However, because I like to check things out , here's what I meant.
(Disclaimer: I don't have a child at either Hampton or Tiffin - I chose Hampton simply because I know more like 1 in 5 get in there.)
Your link's to the GCSE table; I was talking about A-level, which I think is a better guide to achievement. A quick look at the Hampton website tells you that 93% of their exam passes were at A or B this year, compared to 84% for Tiffin Boys (according to The Times' league table Tiffin is something like 63rd place for A-level). Comparably selective private schools (ie fewer than 1 in 10 candidates getting in) are getting 98% A and Bs at A-level.
My point about languages is that not very many Tiffin boys take them - so just 34 exam entries in all modern and classical languages at Tiffin compared to 134 for comparable subjects at Hampton. There are just 24 entries in English literature compared to 54 at Hampton. I think the schools are roughly the same size, with about 10 boys more a year at Hampton.
I'm sure Tiffin is an excellent school and DS2 might well sit the exam in a couple of years' time. You might very sensibly argue, too, that, even if you could afford it, a few points at A-level aren't worth £120,000!
I've wasted far too much time checking my facts now, so must get on with some work!
