I see MFM/FQF tuition rates posted at http://www.math.umn.edu/finmath/tuition/ but I also found a Graduate School or OneStop website that shows a different tuition rate. Which is correct?
The MFM/FQF tuition website http://www.math.umn.edu/finmath/tuition/ shows the correct tuition rate for students in MFM/FQF. (Note that some of the future rates are only tentative, and are subject to approval by the Board of Regents.) Many graduate programs charge the standard Graduate School tuition rate, but MFM/FQF does not. You may have seen a website that shows an undergraduate rate, or shows the standard Graduate School rate, but these would not be correct for MFM/FQF students.
