Eloethan You did NOT Fail the 11+ ! The way it works is that there are so many places available to fill at any Grammer or High school. Then a line is drawn and those above the line go to the Grammar School or High School, those under the line do not and are given a place at the Secondary School or the Comprehensive School. It is NOT about whether you were clever or not. It is about school places and school politics. Sometimes some of the brighter children are not put up for a place because the school wants to show that they accommodate all religions, or say need more boys/girls, or they want a certain school to go up on the stats. We had a situation where the local town had a failing school, so they kept the brightest back in the failing school to make it look better. Not fair on the children but good for the school stats. All decided between the different Headmasters/Headmistresses and the Education Board.
You DID NOT FAIL the 11+ so never tell yourself that again!
I've got another 'keen'... Ouch!
