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 also guess only 5% could describe the scientific method, 1% could describe the use of normal distributions.

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.
