Needing advice on independent boys schools in North West London. DS1 is very bright, but sensitive. DS2 is bright and hardy. Both need challenging and are competitive but don't enjoy being small fishes in enormous oceans. They need lots of positive reinforcement/encouragement. Any advice? Have looked at Harrow, John Lyon, Merchant Taylors, Haberdashers, Aldenham. But it's hard to get a feel.
