Judging a child of 11 on one mornings test was so unfair!!! The 11+ examination had ruined many lives.
Some recent posts on my Facebook Old Girls' group reminded me that there were 12+, 13+ and 14+ exams for entry to my grammar school. I wonder how many educational authorities offered these? DH is pretty certain that the 11+ was your only chance to get into grammar school in his area. My school had a designated form in each year for the girls who joined us later - I'm assuming they had different lessons to catch them up with the curriculum.
To answer the question, I'd say I was one of the popular ones at my small primary school, but tootled along with my own friends, like Niobe, at secondary level, and was very happy with that. I was never going to be head girl!
