<p>What are the differences between IE and OR? My school does not offer an OR major, but it does have a Industrial and Systems major. Is this going to be very similar to OR?</p>
<p>What school do you go to?</p>
<p>As one Prof. from Columbia said "IE and OR are the different sides of the same coin..."</p>
<p>i'm pretty sure you're school has OR in it...it should be there</p>
