Contrary to popular Belief; We in the West Indies actually have ridiculously high Literacy Standard, due to the fact that we speak so damn bad(according to Standard English);
So I got a measly 12/15 = A+ ("I'm Good at Spelling")
Mind you!
This test seems more European English centered, because there were only options for Common
European English spellings of some of these words; So an American or Non-European taking it would be at an immediate disadvantage.
Thankfully(or not, it truthfully depends);
Colonial Rule left our islands with the British Spelling system, but we have also incorporated American and our own system of Spelling.
That being said; This test is inherently rigged!

lol
I can spell well in all the languages that I know; But Regional standards will
always put non-standard speakers at a disadvantage if not of that region.
