This is my 1st time, that I've done this quiz, and I had 8/8 correct, with 1:9 remaining. In my class I'm nicknamed ,,The Worldmap", because everyone says, that I'm extremely good, at countries and capitals.
I can do 168 countries and 121 capitals out of 196 nations. (Without Google searching.)
My capitals leave a lot to be desired sadly but anyway.
Also, don't let what these people said about your grammar affect you too much. Just take it as something to work on.
