That’s a good point. Taking calculus and other courses definitely helped to provide a good foundation. But, for anyone struggling in those courses and wondering if they can make it in this industry: a barely-passing grade in Calculus II won’t be a career-ender. :-)
Eugenia Cheng has a funny quip about how the US is the only place that studies calculus as hard as we do. It sounds like she would like it to be a footnote, and not the main course.
