The most accelerated the standard curriculum allows students to typically become is at a point where they'll have finished Algebra 2 by Freshman year of high school (this isn't the most accelerated students could be, but to be any more so would require summer classes). Typically students will end up taking high school courses at this point, not CC/Uni courses, because either the option either isn't communicated to them (for a variety of reasons), they don’t have the means to get the nearest CC/Uni, or because they lack the confidence to take CC/Uni courses.
The result of this is somewhat interesting, typically better high schools will offer more AP courses (for obvious reasons), and thus most advanced students will simply take the curriculum their schools sets out for them. This is usually: (Sophomore year) Pre-calc -> (Junior year) AP Calc AB -> (Senior year) AP Calc BC. But poorer schools will not offer one or more of the above, so students at poorer schools, if they want to take advanced class, typically get ahead of better schools due to the semester/year course difference.
I went to a shitty (poor, mostly black/hispanic) high school that only offered up to AP Calc AB which I and maybe ~8 other people from my graduating class took. The usual track at this point (for the people that did well in AP Calc AB) was to take Calc 2 at the local CC and basically be done with math thereafter. I was very lucky to have a few teachers that actually gave a shit about me and parents that could afford to buy me a car/pay for gas and both pushed me to take as much as I could at the nearest Uni. Ended up taking up through Calc 3 and Diff Eq my senior year.
