<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>
