<p>You don’t have to relate NY State terminology to anything else (mercifully). </p>
<p>There is a certain body of knowledge that needs to be mastered before the student takes calculus. That body of knowledge is also, more or less, what’s on the SAT Math II Subject Test. So if the student has completed whatever courses are the prerequisites for calculus, the student is ready for that Subject Test. Waiting and taking the SAT Subject Test during the calculus course is not a good idea. There is no calculus on the Subject Test, and kids tend to forget material that was taught in previous years.</p>
