Would the OP have to report Math 16A as a “repeat” of Math 1A on the medical school application?
Math 16A (calculus for business majors) is considered a subset of Math 1A (calculus), and UCB gives no credit for 16A after 1A.
Math 10A and 10B are the usual math courses recommended for pre-meds and biology majors, although 16A and 16B are usually considered acceptable for pre-meds (but the big biology majors require 10A and 10B).

UCB Physics 8A and 8B (physics for biology majors and pre-meds) requires some calculus (prerequisite Math 1A, 10A,or 16A).
