Hey everyone, 
 
Im looking to join an MA program, hopefully in Fall 2012.  I have an undergrad BA from a state school (a fairly decent one, though) with a double in Econ specializing in Quantitive Analysis and Political Science, but only a 2.7ish GPA.  Graduated in May 2010.  There isnt really a trend in the grades either, all over the map with major GPA's around 3.0.  My GRE scores from the one time i took it are 760Q and 600V. 
 
I got an email reply from an adcomm, and after reviewing some of the post here, it seems that my best course of action is to take some upper-level classes through open enrollment prior to appyling.  So here is my question to you -  
 
What would be the best three courses to take before applying in Jan?  
 
I AP tested out of Calc I in high school, so I have credit for that.  I signed up for Calc II my second semester of undergrad, but forgot I did, never went, forgot to drop it before the deadline, and have a nice, colorful F on my transcript (my first one!!)  I also have intro to econometrics, grad-level class mathematical economics (which covered some linear and some multivariable calc), and the first stats class. 
 
I have one summer class, and two classes in the fall that i can finish before application time.  Would I be best served to take all math?  Or what i'm leaning towards now - two math and the first grad-level microecon course?  And the bigger question I guess, would I be best served in the eyes of adcomms to take calc II and calc III, or intro to linear and linear? 
 
Any help would be greatly appreciated, I want to get into a decent (gpa, i know) school and have NO idea what would look best.  Thanks!
