From what our school said,
These few years,
99% of the students in Singapore that take A levels pass H2 Maths.
More than 50% of the students in Singapore got an A grade for H2 maths.
Is it true?

Plenty of my peers had A for Maths.
So if I extrapoliate this case and take it as a representative sample and apply a weak form of the central limit theorem......maybe.
