I left grammar school in 1964 with just 5 O Levels, because I failed all my A levels. I preferred playing guitar in my band which was infinitely more fun than studying. However, I did eventually pass Institute of Chartered Accountants' part 1 Final exams but became time barred before retaking part 2 for the 3rd time I think it was - so that gives me roughly 8 A* passes at A level by 2017 standards!!

I have been out of work for no more than 3 weeks in total since September 1964!
University is a complete waste of time for the majority of wasters there.
