it's not actually a problem, the 13+ entry; after a bit if swaggering both sides, they settle down. They do take a rigorous look at GCSE results and some have to leave if they don't get the required points, but there's usually four warning befire then. There's another entry therefore in the sixth form, usually outstanding mathematicians...
If you can get into eg St Olave's you'll have no problems at DC. Even if you can't, you won't have problems, they're good at bringing boys on.
The scholarships go up to about 30% of the fees. Thereafter you apply for bursaries, up to about 95% but it is done case by case and yes, some get more. They are quite rigorous and you need to declare all your income and assets; they are v keen to avoid parents gaming the system which in effects removes resources from other needy children. I think about 30% of the school gets some support; you can look it up in their annual report.
They are v good at rugger and chess...and debating.. they used to have a hen club...I mean a poultry club...if you want music I'd prob aim for Trinity if ds is a v good musician, or a music school; for acting Alleyns. DC isn't bad, just it plays less if a part in the thinking imv. That said, they encourage the boys to audition left right and centre and quite a few do fit their school round eg filming. I think their art is rather good. It's the sort if school where if you want to start a new activity or society they say why not rather than no.
the Headmaster has, in my view, a v balanced view of the world. It comes out in how he deals with the inevitable issues. It means that I think they emerge quite emotionally mature usually quite nice young men. He's been working to push standards up but there is, in my view, still some way to go in a few areas. But one of the joys of the school is that it is hugely inclusive, across the social spectrum, wealth, religion, class, background, housing, nationality. It is so not a school for just one or two types of parent or boy.
Pastorally, although it's a huge school, they divide it up into lower, middle and upper. Lower is in its own area. So you never feel it's so huge. It's an excellent way of doing things; basically when you are a small unconfident new shrimp you don't get trampled on by huge hairy monsters.
