(so did I, *sardine! HM was PP)
Blu their academic ability isn't being speculated on, I think that, knowing the school, we're commenting more on newspaper's blithe assumption that all the boys will be going there when it's a very competitive school with high academic standards and if they don't pass the exam I'd be quite shocked if they were accepted tbh. Also, based on knowing it, it really is not a school which would compromise academic standards and the girls equivalent has been known to turn down very substantial (I'll buy you a new swimming pool) 'donations' by parents desperate for their children to get places. If they get in it'll be on academic merit but my first thought honestly was 'they'll have to pass the exam first'.
I would have loved to go to Haileybury - used to do MUN conferences there.
