Do like me. I have a BsC in Economics. No RA, no Stochastics, no ODE, not even Calculus III. What I have is a strong liking in Mathematical Economics. You could see that in the SOP. In the list of my Math courses I put Game Theory, Econometrics and Operations Research as Math. Hell I even put "Macroeconomics of Growth" because we basically covered all of Barro/Sala-i-Martin, which is pretty technical and mathematical. So in total I had 13 math courses in a BsC in Econ, no Minors, etc etc. Not all of the QEM Courses have mathematical names in them.
Also I´m very disappointed with the QEM organisation. They were supposed to find housing for us, it´s what stated in their website. But guess what, they didn´t this year, for 8 of us. And some more comments here make me fear the worst is yet to come.
