Chances for a junior (Columbia, NYU, Barnard, Uchicago, Umichigan, Syracuse, Duke)

Does an A- average put you in the top 1/2 at your top boarding school? Also, may I assume there are not more than 10 AP classes offered at your BS. Taking out your father’s relationship (hard to gauge), I like you for the NYU/Michigan level. Chicago, Columbia, Yale, Barnard and Duke seem to be different degrees of reaches.
