If you can't be bothered reading the thread you started like post #32 by Taildragger67 then you have no chance of getting an 'A' level in anything due to having to research the subject yourself.
Get your GCSE's and find a job in a company where you can start from the bottom and work your way up the ladder on merit. Become an office monkey for a corporate company, become a runner for the BBC, Join the Army as a front line soldier ... actually scrap the last one - I don't think they would trust you with a penknife never mind a rifle.
