asian/chinese families play the system. U cannot say our kids are smarter, but surely they work really hard. I personally know many white kids, chinese kids are smarter than my son, but my son got better scores on gpa, act, sat; he works harder than other kids, including some chinese kids. One cannot say: ok, I am smarter than u (my son here), and so u should not study hard, and I can do better than you in test to reflect our IQ difference.
So I truly believe, even if there is a difference in IQ, that difference should be overcomed by efforts.
