Until North London Collegiate was set up in the 1800s girls just weren't properly educated - they learned to play the piano and have social graces which is why you don't have the same traditions. NLCS is pretty good as someone mentioned (day school though). Similar academic standard to Eton. Oftne beats it. St Paul's girls but again day school. Cheltenham LC probably beats Harrow in terms of exam results. Downe House? Whycombe Abbey - academic girls boarding.
