well, in some ways as someone who would most definitely lie, cheat connive and stretch the mortgage to get my kids in a better school if possible, I'm not going to judge this dude for that.
I went to comps of varying quality myself - no better way to know how much difference a good school can make to how happy your kids are.
and no, bright kids don't do well if you park them just anywhere - funnily enough teachers do actually make a difference. If a teacher is pitching their lesson at C-grade, to engage the majority of the class, the A-grade student is not going to be pushed - they may not even be taught everything they need to know to get that grade.
I will judge him for his tone, the fact that he is making out it was all terribly difficult - i mean, all he did was move house then apply to a school by the normal mens...and it doesn't sound like he ws short of the wherewithall to make that happen.
I don't know anything other than the details on this thread about the schools in question though!
