Yes, normal college pace is similar to calculus BC (including AB material) in one year, while calculus AB covers material more slowly.
What is the context of this notion, and the notion that calculus 2 versus calculus 1 or AB is significant for this purpose? It may be helpful to mention the desired colleges and intended major.
Note that only a few US colleges and universities require or recommend calculus while in high school for frosh admission (and they do not specify calculus 2 or BC).
While accelerating an additional semester of math may be less essential than you might believe, one advantage of taking a college course (at an actual college, not “college in the high school”) while in high school is getting experience with how a college course runs (meaning less supervision and requiring more self motivation and time management) before jumping into the deep end as a college frosh.
