Ana most pupils took 9 'O' levels at my school, although I dropped Art for some reason.
However, I took up art again in later life and passed a B Tech.
I think the standard for getting into university is probably lower - simply because there were far fewer universities in the 1960s, and many students went to Technology colleges and polytechnics, as well as those who went to Technical College, then entered the world of work and carried on at night school.
And in those days many parents expected a child to start contributing to household expenses as soon as they could. It was markedly noticeable that, although grants were available, it was the few who had more wealthy parents who were able to stay on for 6th form and then university.
To suggest that someone should have declined a place earned at a grammar school at age 11 because they may not stay on after 'O' levels and offer that place to someone else is ludicrous.
Some children took the scholarship again at 13 and could move schools then. A couple of my friends did that.
Having said all that, I do believe that comprehensives should offer all children a fair and equal opportunity to be educated and learn to the best if their abilities, and no, my view of comprehensive education has not been learned from the tv as I have never seen any programmes about comprehensive schools (apart from a couple of episodes of 'Big School').
My knowledge of them is from real life but only relates to the schools in the areas where we have lived.
It depends where you live as to whether they are good, mediocre or have been put into special measures and if you have no choice then DC and DGC have to take their chances.
