I was wondering the same thing when I was doing my AMCAS last year 🙂
I entered my AP credits along with my first qtr. freshman year classes, and AMCAS didn't change it, and none of the schools I applied to ever asked me about it, so I am assuming that what I did was OK (they even let me in! :wink: )
Just make it easy for AMCAS/schools to find the AP credit when they look over your coursework. When I read the instruction book last year, I vaguely remember that AP was supposed to go with FR year coursework.
As Spiderman mentioned, we don't take the AP classes in college, but if you are like me, you did get college credits for those AP classes. My the credits posted first qtr., so that is where I put them on my AMCAS - instead of as summer or HS classes.
I think NineSixteen's idea sounds good too, and listing them as OT seems fine. Do whatever you think sounds the best using your own logic.
