You have no proof that the top 10% of Garfield High were of superior heritable intelligence.

I'm getting the feeling that there is no level of evidence that will convince you, but here goes:

Do you suppose that the least intelligent students took the calculus class? Would he have allowed anybody who had not done well in the prerequisites (Algebra 1 & 2) to take the class?

No level of evidence will prove to me that average kids cannot do excellent work. You're right. Obsessing about IQ and genetics is a waste of human talent when there are many other variables that can overshadow differences in that metric. I had seven year old kids factoring quadratics in their heads and doing calculus at 11 years old.

I don't buy this BS about IQ.

Would he have allowed anybody who had not done well in the prerequisites (Algebra 1 & 2) to take the class?

Indeed he did, depending upon his intuition about the will of the kid and the barriers to be overcome. In some of those cases the barrier was language, so he taught them English.
