I failed my maths O’ level, back in 1969. Maths was always my worst subject.
For some ridiculous reason, I decided, 25 or so years later, to have another go and attended Maths GCSE evening classes.
Why oh why? I was still hopeless at it, but gamely persisted.
One evening, at home, trying and failing to do some of the homework, I just cried. My DH shouted to my son, ( who didn’t take after his useless mother in that department) “Help your mother!!”
He rolled his eyes, reluctantly did as asked, but he knew he was on to a losing cause
I failed the exam yet again!
Didn’t stop me from spending all my working life in banking, and managing perfectly well without my qualification.
