Hi, sorry to raise this issue again, since I am encountering quite similar situation here. If you have been accepted to the MFE, can I know how have you satisfied your condition? I've been accepted to Columbia SIPA, but they required me to take a Calculus class and get a grade of B or higher. In your case, did you take the summer school? If so, do you have any reference for cheaper summer program that provides math/econ courseworks? Any information you provided will be much appreciated! Thanks
