Oecd' countries japan and korea are successes at pisa' tests, but they also have better potential.
While iq' is calculated so "whatever is average" is called 100, the averages locally in japan and r. Korea tested as more intelligent. For them to succeed at solving math was easier. For them to get 1550 in pisa is expected. For math 527.
But take a country like u. s. Our 15 year olds ARE the average, 100 iq, only a bit above 100, score 1468 surpassing sweden despite average intelligence, still scored high 465! Like 88% of their score.
Isn't that a bigger accomplishment?
And don't even get me started on national quality... called i. c. i. We got the only a+ in oecd by climbing from average intelligence.
Isn't that a bigger accomplishment?
