When you read the AMCAS instructions, it'll tell you to put down everything and be honest because if they catch you lying, they'll kill you. I believed them, and I put down courses that didn't appear on my transcript (I'm an Oberlin grad).
HOWEVER... AMCAS won't accept the tiniest discrepancy between your official transcripts and what you wrote. So even though they tell you to put this stuff, in fact your application won't even be processed. Mine was held up forever. My advice: Shell out the $5 and have an "official" transcript sent to yourself. Don't use online records of your grades or a "student" transcript, because they may have slightly different info than your official, and it will BITE YOU IN THE BUTT.
