<p>“Don’t do IOE if you want to do FE for grad school.”
Lol please stick to area you have a clue about. Operations research (the math modeling part of IOE), which encompasses stochastic calculus, linear/integer programming, calc based stats etc, is the foundation of FE. There is a reason the Michigan’s FE program is housed in IOE and more than half of the professors in Michigan’s FE program are also IOE professors</p>
