Skycaesar,
Its NOT the end of the world, there are other airlines out there apart from Saudia?or LHI .Youre not the first person to have failed the DLR and you wont be the last!
Its up to you now to move on and make your career happen,sitting on here blaming an aptitude test for ruining your life is pretty stupid to be honest!!
Dont give up, youve come this far ok. For what its worth, the DLR is bull

in my opinion.
