Your college transcript will list all your AP courses. List them as they appear on your COLLEGE transcript, NOT the little one you got from the College Board in high school. You can designate them as AP courses in AADSAS. Make sure you get your own copy of your official college transcript because certain ones like "degree progress reports" may not list the AP credits that transferred over.
Meanwhile, I don't think you have to, but I mailed AADSAS a copy of the College Board's "transcript". It's not really a transcript, but just a listing of what exams you took and what scores you got. Just call the College Board (# is on their web site), pay something like $15, and they can mail the stuff right to AADSAS. After a few weeks, AADSAS said they had received that transcript for the AP credits. Again, you might not have to, but I just wanted to make sure no one could complain that they didn't get anything 😉
