What has been your most influential/useful course?

[Kaz]

If you had to narrow it down to one course that you use daily in life or have been the most influential and beneficial which one would it be?

Not used in my daily life, but definitely most influential would be Calc1. I failed it the first time I took it. I was stunned because it was the first thing in school I cared about and tried to do yet still failed. That moment got so "in my head" that I switched majors to math (formerly I.T.). You read that correctly: I went completely away from the classes I was acing (English, history) and instead invested myself in something that apparently was my worst subject. The result was I stuck with it for a very looooooong time and graduated with a bachelor's in math (and psych, funny how life works out lol). I have no idea if that was the right way to go, but it definitely was the most influential course I ever took.
