<p>I am at a school where OR is offered as a major, and the CMU program is more inline with what I have taken/will take. I’d say if you plan on going on to do graduate work in OR, it might be better to get a math degree, as at the graduate level OR is quite theoretical and math-y. A friend of mine was a math major and is now getting his PhD in OR at MIT. While NU’s IEMS is great (I have done research with department during the summer and have only great things to say about it), it might be too applied and not as focused on OR (more general engineering and industrial stuff) as CMU.</p>
