"Shanghai, participating for the first time, outscored the previous world leader, Finland, in all tests, as did Korea. The top five also include Hong Kong and Singapore, participating for the first time."
With these new additions now participating says it all.
Asian are know for strict schooling.
Without them we would still b ranked as per before.
Thats my take on it.
Oh BTW we the parents need to take more responsibility as per longrunsthefox takes. Good onya longrunsthefox.
