Thanks for this enlightening post. I am on the same boat as I am still not sure if I would like to pursue a Master's Degree in Econ or an MBA.
I am leaning towards Econ as it seems more interesting.
As you said, a grad econ is mathematically challenging and I come from a completely different background. I was thinking maybe take some undergraduate courses in calculus etc. I am very much willing to learn though. What do you think, do have I lot to catch up on and would it be realistic for me to pursue Econ?
