For grade, I would just select "CR-Credit", since they don't care what your high school grade in the class actually was...and for term, it seems like some people are doing it differently. Mine is listed on my actual transcript as "Fall A 2006" (I entered college Fall 2006), but since there is no "Fall A" option on AADSAS, I just included it in Fall 2006...but you could probably also create a separate session for the AP classes and call it the summer before you entered college.
