When I was going back in to put my coursework into AMCAS I saw that there was a clean breakdown in the psych classes between those that are bio-oriented (neurophysiology, biopsych, psychopharm, abnormal psych, sensory psych) and those that are purely psych oriented (animal psych, methods in psych, social psych, etc). It should be pretty evident once you are in these classes into which category it falls (bio or non-science) and like was previously mentioned psych stat falls under math . Understand that this grey area is one of those regions that AMCAS may actually be flexible I have heard of people having some psych classes taken off their BCPM and put into non-science but never the reverse. Although I did not do this myself since I performed better at the bio-pysch courses, it may be of some advantage to play with the margins and if you underperformed in a bio-psych course you could include it in your non-science and if it isn't moved back then it will not be there to harm your BCPM.
