I was born in 1944. I passed the 11 Plus and went to a Church school, which covered a large area. It was also a Secondary Modern for the local area. The Grammar side had 3 forms, A, B, & C whilst the Secondary Modern side had two forms, D & E.
After WWII, 'The Bulge' started. By the time I left school, the fisrt year extended to 1H!
Of course, not long after I left school and started work, the bulge started to emerge onto the employment market.
Our Group Scoutmaster used to chat to us older boys after weekly meetings and gave the lads who were on the verge of leaving school a warning.
He worked for Van den Bergh & Jurgens (part of Unilever) who manufactured Stork Margerine in the main.
Their apprenticeships were well respected and sought after and they were now being inundated with applications, so they had found a devious way of reducing the numbers.
They held an examination for all applicant, each of whom was provided with:
A sheet of blotting paper; A rough sheet; An answer paper and A question paper.
At the top of the question paper it said "ALL WORKING MUST BE SHOWN ON THE ANSWER PAPER".
At the end of the exam, every sheet of paper was collected from each desk. If anything had been scribbled on any piece of paper other than the answer paper, it was an instant fail. The answer paper might have been 100% correct but it wan't even marked.
Reason for failure? 'Cannot obey a simple instruction.'
