Asian and Chinese aren’t coextensive. ~25% of US Asians are Chinese and Asian Indians (another ~25% of US Asians) are a fairly high performing cohort as well. Your just presenting evidence the 1965 Immigration and Nationality Act selects on educational performance with respect to Asian immigrants and not much else (and certainly not the everyone learns calc bc in middle school nonsense)
UK results for middle-school GCSE performance below.
Calculus is covered in the GCSE curriculum.
You can see the "Chinese" category is above every other category of "Asian"
And I would expect comparable results in the US, given the similarities with the UK.
