I guess not. You trying to explain to me why Finland is smarter after the studies show that America is like me telling you about why America is better than Finland. It wouldn't really tell you anything you didn't already know. 
What the fuck does the IQ scale have to do with exam grades? Are you fucking retarded?
You've yet to explain how Finland is smarter after claiming they were for 9+ pages.
OK, last few pages have been about the statistics and how they are formed in terms of populations of 5million people vs 300 million people.
Another issue was, if finland is superior in terms of IQ to america, or vice versa.
Now, the second issue is easy to close, as we learned that americans have an average IQ od 97 and finns 96. So you won with a point. Congrats, you outsmart us anytime

Then, the first issue. You have yet to explain how it is easier to get a better average IQ in country where's only 5 million people, compared to US with 300 million people.
