Rather than taking a direct and honest approach at answering your question, I'm going to take an indirect and less honest approach which MIGHT not be censored by the education mafia.

If you look at the 2007 TIMSS math scores for 4,208 students in Botswana, 5,294 students in Ghana, and 3,407 students in Hong Kong who participated in this study, you will see that only 6 students in Botswana scored higher than 595 and only 7 students in Ghana scored higher than 585. If you take a detailed look at the Gaussian Distribution of these scores, you will see that NONE of the 4,208 students in Botswana and NONE of the 5,294 students in Ghana scored higher than 597.

So how does this equate to "IQ" that you are asking about?

The AVERAGE score for the 3,470 students in Hong Kong who took this test was 607, and NONE of them scored lower than 401 (37 points higher than the AVERAGE for Botswana of 364 and 92 points higher than the AVERAGE for Ghana of 309).

Professor Lynn graciously puts Hong Kong's average IQ at 107. But he also puts the average IQ of Japan at only 105 and of Korea at 106 even though those two countries score higher than Hong Kong on many of these international tests. So it would be conservative [or perhaps more reasonable] to estimate that a TIMSS math score of 607 is equivalent to an IQ of 105, a score which NO student in either Botswana or Ghana achieved.

Does THAT answer your question?
