I too bitched interminably when I failed the SCPL exams time and again in the 1960's. Then years later I went to England and bitched interminably. This time about the idiotic Air Law exams which asked me about the lights on tethered balloons. A lovely old English lady former school teacher with whom I was boarding at the time, had heard it all before with her students. She ever so gently told me to stop bitching and get on with it. She was right, of course. It was the best advice I ever had.
I realised then that my interminable bitching was never going to help me pass exams. People simply weren't interested in my problems. They had enough of their own.
My advice? Realise that most readers are genuinely sympathetic towards you. But try to stop bitching on Pprune because no one can pass the exams for you. You will get there eventually. Perstistence always pays of in the end.
