<p>If I recall correctly a few years ago the GSB, now Booth, began an undergraduate access initiative to open up some courses at the graduate school to undergraduates. I also seem to recall these were somewhat limited, but it might help one get to know the faculty at Booth, which might allow one to take or audit a course. It has been my experience that almost anything can be accomplished at Chicago if one really wants to pursue it and can find the right people.</p>
<p>I looked at the MSFM program. I looked up a couple of the courses and they seem to have some hefty prerequisites. I noticed that some of the courses are cross listed with other disciplines, Statistics for example. It might be possible, assuming one had the right background, to at least enroll in some of the courses featured in the program if not the program itself as an undergrad.</p>
