I've only ever been in church schools so I don't know what private education is like, but the facilities seem amazing, I gather the teachers are top notch (Oxford and Cambridge graduates), class sizes average 8, and the boarding houses look wonderful.
I want to study art history and I can only find it at private colleges, so I don't have much choice, but as for stigma I kind of understand, but I can't imagine any opportunities only available for state students, if anything it's evident private school students get an unfair advantage at getting into the Russell Group universities.
