Hi,
My preferred major at most colleges is applied math/operations research. However, they do not have this major in any of the UPenn schools. Which major is the closest to mine?
I suggest you do your own research. You can find the UPenn course catalog register online (a two second google search found the link below) and then look through the courses in any related major to see which major would be the best match for your interests. https://srfspdf.apps.upenn.edu/srfsPdf/jsp/fast.do?fastStart=courseRegister
