sticky absolutely.
Though so much is cultural; I attended a state of a school, really awful pit closed down soon after I left. I think of the kids there from my estate only two of us got GCSEs full stop (I am 38 so you know, a fair few eyars ago now....). Were we encouraged to even consider anyhting academic? nope. Not until I went back in my early thirties and took an Access anyway, just to get abck into the swing of things, at which point one RG university approached me on the suggestion of my Lecturers, another offered me a palce without interview.... and I took the far less competitive one becuase I felt so out of palce and just inherently wrong there.
I am doing my MA now though and ahve been told that they would support me for a PHd should i ever choose to follow that path so I got there eventually but damn it took a long time! Same experience for my sisters- one just got her defree, a first, at 36 studying PT and working FT becuase she was led to believe she had no ability, and the other has risen to the top of her field without a degree after sheer graft because she had to elave university for financial reasons (basically degree emant shift work so she could not get PT work, and parents couldn't help).
I've been taken out by other factors but whilst sister-with-a-first drives a Sabb and has six bed house so is definitely doing well, I still wonder what they might ahve been capable of if they'd had a decent education to start with.
