What classes do you use on the job?

<p>For those who are working or have worked in an engineering capacity, are/were there any courses you've taken (undergrad or grad) that you actually use/d on a regular basis in your job?</p>

<p>Put another way, is there a task or responsibility you couldn't perform, or couldn't perform as effectively, without having had taken xyz class?</p>

<p>I realize answers will be major and/or job dependent, but any and all perspectives are appreciated.</p>

<p>I also realize I am probably asking a shortsighted question, so also feel free to lengthen my view.</p>

<p>Ninth grade typing!</p>

<p>Regular basis? Probably not. Having had a class so I know what to look up when? All the time.</p>

<p>I’m not an engineer, but classes I find useful in life are:</p>

<p>Calculus - Understand the relationship between position, velocity, and acceleration (and how the concept shows up in lots of other areas).
Physics and chemistry - how the world works
Economics - marginal cost vs marginal benefit; average cost; utility
Statistics - so you don’t get snowed by them</p>
