Am surprised to see Australia rates highly. 40% of students don't know it takes about a year for Earth to orbit the Sun.
I would guess that half the population doesn't understand compound interest.

I would guess that 20% of locally born Australians would not know how to use punctuation or grammar for clear expression.
Is this a worldwide trend? The rise of flerfers suggests it is.
Aren't ads dispersed throughout the discussions? If not, then why not?
