mit's opencourseware has quite a few classes up from course 15 (sloan school of management). worth a look.

15.010, maybe 15.060, 15.062, maybe 15.063, maybe 15.223/15.224, 15.351, 15.352, 15.356, 15.358, 15.369, maybe 15.391, 15.394, 15.402, 15.414, 15.431, 15.433, 15.616, 15.617, 15.628, 15.963, and 15.997 look interesting.

15.501, 15.511, 15.514, 15.515, 15.516, 15.518, 15.521, and 15.535 look like particularly interesting classes on finance.

i should also peek at 15.070, 15.075, 15.081, 15.084J, 15.085J, 15.093, 15.094J, 15.098,15.099, just to make sure i haven't missed any of the math there.
