With only a high enough AB AP score plus a non-transferable high school multivariable calculus course, you would still have to start in calculus 2 in college, just like having only a high enough AB AP score (best to check the college’s old calculus 1 final exams, though).
A college multivariable calculus course would generally list calculus 2, or a high enough BC AP score, as a prerequisite.
