Econ majors and course lists on the AAMCAS

I'm not sure if this has been mentioned before, but I was wondering how I should classify my Econ courses on the AAMCAS?

Some are clearly not meant to be BCPM courses (i.e. environmental economics) whereas others are less clear (economic statistics, econometrics, intermediate microeconomics, etc). The last three in particular are math-intensive and would technically be 'applied math' courses. However, they are not cross-listed in our math department, so should I list them as 'AO' courses?

A minor technicality I realize, but it will affect my BCPM GPA significantly either way.
