Just to reiterate what the above posters said, you have to submit all transcripts of postsecondary classes. I know this for a fact because I didn't think I needed to submit a transcript from a community college where I attended ONE P/F athletic class, and my AMCAS application was held up for a month because of it. 🙁 I didn't use this class for credit at my university but AMCAS was still able to track it down.
