I really don’t understand the issue, state/private are not personality types?!
This is true, but the make-up of the student body does have an impact. As a state school student in Edinburgh fifteen years ago, studying an arts subject with a high % of private school pupils, it did affect me.
The sheer confidence drummed into private school kids, and the ££££ spent on making them as articulate as possible meant they could dominate lectures and seminars and sound intelligent. I spent my first year panicking they were so much cleverer than me.
I also remember random things which made me feel like an outsider like the first seminar after the Easter holidays when they all turned up tanned and well-rested as they’d been skiing or to somewhere exotic. While I’d been working full time in a shop!
And, as someone mentioned above, the questions about what school I’d been to, which completely baffled me at first. Until it slowly dawned on me that their world consisted of fifteen or so private schools, and either you’d been to one of them, or you were irrelevant.
