I brought in AP Stats credit but never took any straight-up math courses during my time as an undergrad (though I wish I had). No econ, no nothin'. Was going to audit econometrics, but my schedule was too packed. That said, my thesis, which was accepted for a panel discussion at a national conference, was based around an fsQCA analysis, which combines quantitative and qualitative methods (see the work of Charles Ragin). I worked one-on-one with a professor to learn everything about fsQCA in order to effectively use it. So, what I had in "methods training" wasn't formal or exclusively quantitative. Then again, I didn't get into a number of schools that are known for their quant-heavy approaches.
