Hi OP - congrats and what a nice position to be in.
IMO you do need a straight forward school journey - if Trinity not close by then you won't be able to get the school coach and the journey is not really doable - scholarship or no..
Dulwich - if they were offering you a scholarship they would have mentioned it in the email. The letter won't bring any revisions on that front? It's a great all round school with an inspirational head who believes in an education that's wider than the GCSE and A level syllabuses. That's pretty rare these days?
The same, tired stereotype of alpha males always comes from that poster. There are alpha males in every single one of these schools (and indeed in every single school nationwide!) - they're both big enough to attract all kinds of different boys who all find their own niche.
The Eltham head is v ambitious and exam results have improved massively with him in charge. He always tempts high performers with generous scholarships (50% is standard) and the new co-ed environment will be interesting to see. Did you want coed as all your other options seem all boy?
The comment about Dulwich and Eltham both taking kids who don't meet the grammar school 11+ level is also an odd one. Seriously don''t know a single kid who failed Bexley or Kent and then went on to get a place there?
Olaves seems to be chilling a bit after that awful old head who really was only focused on exam results and league tables - but clearly won't have the same small classes/level of funding that the others have?
Don't know anything about Westminster as never wanted to put ds into the London commute at 11. Clearly a great school with an amazing history.
No easy decision - but remember that it's down to what suits him best. The ethos and the commute. He will end up with similar grades at any of these schools IMO.
