I have only skim read, but I have friends with DC at EC and they have chosen the school because it’s less of a pressurised environment (apparently) and also their kids are very sporty. Schools in this part of London (SW area) are ridiculously competitive entry (some are more competitive than Oxbridge at 11+ in terms of numbers of applicants to places). An ‘average’ child (in terms of national standards) may struggle to get into any schools at all. This has been the case for some years and it’s getting worse, year on year as competition for limited places increases. The Oxbridge process is nothing really for kids who have gone through competitive exams and interviews for 5+ schools (some are sitting many more) when they were aged 10 / 11. Rejection is something they got used to early, in the majority of cases. Also, it’s hard to feel outstanding in a school where all 9s at GCSE just makes you average. Some thrive on this, but for others, it can knock their confidence. This is why many families have to go for ‘flexi boarding’ out in Surrey. St John’s in Leatherhead is a similar set-up to EC and kids either get school buses out from places like Putney daily, or they flexi-board. I know quite a few families with kids who do this.
As for the super-selective schools in London, I can only be honest and say that there is no special or discernible ‘extra coaching’ going on at all, My DC only ever had a teacher who glanced through the personal statements a few days before it went off. No advice on college choice, apart from ‘go for ind that feels right to you.’ All the ‘extra’ stuff they did, they did it external to the school and the teachers weren’t even aware. There was a talk about Oxbridge applications in the March of Year 12. That’s literally it. I think some people imagine there is some kind of special intervention going on in these schools - well, I’ve seen no evidence of that. What can the school actually do anyway, beyond write a reference?
About 20-30 get in most years, but probably double that will apply - so they can hardly be giving detailed guidance to 60 kids applying across the two unis for a whole range of different subjects. There was only one ‘Oxbridge Advisor.’ Very nice man, but there was nothing he said that was ‘guidance’ really. He just sent out emails about deadlines. The best source of info was TSR and MN!
It’s hardly surprising that SPGS get about 30-40 out of a cohort of 100 in because it’s probably harder to get into that school (relatively speaking) than it is to Oxbridge. But again, it’s not the school ‘getting them in,’ they are exceptionally bright girls to begin with! Still many will be turned down though. It will vary year to year anyway as some courses are much more competitive than others. I think there a great deal of luck involved and the difference between those who get in and those who don’t is wafer thin. Places like LSE are probably just as competitive and they don’t even interview - it’s all about the PS! Is that fair (given some kids will get someone to write it for them)? It’s all a malarkey at the end of the day and all you can do is throw your hat in and see what comes up. EC can’t be ‘failing at Oxbridge’ because EC is not applying! It’s all down to the individual - whatever school they are at. Everything is contextualised. If you’re at an independent or selective, you may need to do a bit ‘more’ than get top grades these days, but so be it. The schools are full of very high-achieving kids and this is not beyond them. Most are doing it anyway off their own bat.
OP, your DC will be judged against the average grade profile in his / her school. If they are above this, then they are not at a disadvantage. Don’t wait for the school to ‘guide you’ - because they won’t. No school can ‘get them in.’ They have to do it themselves and, in this sense, it makes no difference whatsoever who else from the school gets in or doesn’t get in in any given year. All that matters is their application.
