why i didn't do well at school

During recovering from a heavy night out last night i sat down and watched one of the many music channels... it was playing non stop 80's tracks, now i see myself as a child of the 80's even though i was born in the late 70's, i spent a significant amount of my life growing up in the 80's. It was also during this decade that i was most impressionable... now i haven't heard some of these recoards for a while i would say for some of them I haven't heard them since they were realised and yet i could sing allong perfectly word for word.
Now i wasn't great at school and until now i put that down being dyslexic, being bullied, crap teachers etc. But now i wonder if Duran had sung about the Battle of Culloden - 1746 or if Wham had made refferences to the periodic table maybe I would have done better.
