Bazzaman96 please read the entirety of this thread; you will hopefully understand then that employers are not interested in your exam results.
The job situation is probably better in UK than in most other parts of the world, with the probable exception of China. When the US finally sorts out its dire airline industry, it will once again be a big consumer of pilots, but that won't be for a while yet - and you would have to be a naturalised US citizen with a Green Card and a good few thousand hours flying in commuters before you'd get a look at jet airliners.
There are contract opportunities in many nations around the world for experienced pilots from Europe and North America, if what you're interested in is flying overseas. If your interest is purely in improving your chances of employment, you're probably best off staying here.
