Readers of this blog know that I had little math training coming out of my undergraduate program and my selection of grad programs was narrowed. I ended up getting into Mizzou largely because the director of undergraduate studies at Mizzou knew one of my references from the University of Nebraska, Omaha. My reference remarked that although I my academic credentials didn't show it, I thought about things "the right way."
On this subject, there is a very interesting discussion going on over at Marginal Revolutnion regarding the level of math necessary to succeed in graduate economics programs.
