Well i have taken the following courses:
Calc 1,2,3 (includes multi-var calc)
Linear Algebra
Differential Equations
Intro. to advanced math
Intro. to econometrics (from econ dept)
Prob and Stat (non-calc based)
what other courses would be useful?...and how practical/feasible would it be for me to take econometric courses (w/ econ dept. of course) once i get into a poli phd program?
