Dude, you have no damned idea what you're talking about.
You are extrapolating from N=1 to a state of 36,000,000 people. Your experience is not the guiding star for state-wide policy.
Also consider this... the people who work on this stuff, have spend years and years on this stuff. Perhaps... they... know what they are talking about?
As someone with a kid, introducing subjects before kids are ready for it is counterproductive. It can cause confidence issues later, and doesn't help them learn earlier. By way of a small example, try to teach a 3 month old how to walk. Good luck, you aren't doing anything useful.
Now back to the immigrant thing, by now you surely must have realize you are in the upper X percentile of your peers from India. There are many many many, in fact most, Indians, who cannot do what you can do. Not even close. Basing educational policy on what you found easy with your Xth percentile intelligence is not going to be a great idea.
I am sorry but I don't think you have any idea of what you are talking about. No, I am not N=1, nor was I upper X percentile of my peers in India.
CBSE and ICSE boards, 2 of the major boards of education in India had calculus in grade 11 and 12. This wasn't me being exceptional, it was standard practice and millions of us learnt it. The millions of kids in India in CBSE and ICSE board education is much higher than CA's population.
You can check out the syllabus for grade 11 for ICSE board:
Very basic differential calculus was introduced in grade 9/10 and then by grade 11, we were performing decently advanced differential calculus. In grade 11, integration calculus was also introduced and it went on to pretty advanced level by grade 12.
Calculus was also used in our Physics classes, so it was pretty much needed.
