Well, you've have a couple of people tell you, and a faculty advisor tell you, nearly every school has a full year as a requirement.
EVERY SCHOOL I have researched (dozens) has in their admissions guidelines: 1 year of general chemistry, and 1 year of organic chemistry (or 1 semester organic, 1 biochem).
I have literally never seen anyone list anything differently.
It sounds like the ones you are looking at that do not require it are in the minority?
Even in the link you posted, the two semesters + 2 orgo + 1 biochem was recommended. I understand not wanting to waste time/money, but do you really want to do just the bare minimum of what is required vs/what is recommended?
*EDIT: I think I see what the deal is. Looking a BUCM, Tufts, and a couple of other places, they are willing to accept AP for general chemistry- Provided you still go through two full years of chemistry in some way.
So, even if, for your institution you AP'd out of the first year or part of the first year of gen chem and fulfilled a degree requirement that way, to satisfy admission requirements for medical school, you need to physically take two full years (1 1/2 at Tufts) of chemistry in some combination that includes general and organic, possibly biochem.
