That sure would be nice. However, if you did not take the AP exams - or even if you DID take them but failed to report your to your undergraduate registrar's office - then no cigar. In short, if the credit for an AP course does not appear as transfer credit on your collegiate transcript, it cannot be listed on AMCAS. Your second quotation says this fairly explicitly.
As regards the instructions cited in your first quote, my high school offered specialized "CollegeNOW" classes whereby you were issued college credit for some advanced math and science classes. These were taken at the high school, but grades were reported to a local community college, and all participating students received a transcript from that college detailing the pertinent credits. I think that's the sort of non-AP college coursework they're referring to.
Ah ok, that makes sense. I wasn't familiar with any type of program like the one you described.
Thanks!
