One of my granddaughters lives in a 11 plus area and, being all of 8, her parents should be agonising over schools, exams, tutoring.
She is brilliant at art, dancing, gymnastics but not academic, she's never read a book willingly, so thank heavens no worry or stress or disappointment over the iniquitous out-dated 11 plus for her.
Where I live there's one comprehensive school and all the children go there.
I went to grammar school when they gave a good education to any child with brains. It didn't depend upon your parents' class and income as it does now.
