I was a psych major and, as someone said before, I had more than enough credits left over for electives. Although, you might have less since you'll probably have more required classes for you major. Sadly, all the biochem-type courses/electives that I took were through the psych department (biopsyc, psychopharmacology, cog. neuroscience, sensation/perception, etc) so none of them will count towards my BCMP. 🙁
