If you have the aptitude for it, I'd argue that being constrained by clean, cold, infallible logic makes STEM subjects much easier, not harder, than the messy human whirlpool of the humanities and social sciences. Sure, it might be easier to get away with BS in those fields — but what if you actually want to learn something or make a tangible impact? No matter how you slice it, humans live in the world of "fuzzy-logic-based natural language," not bits and bytes. (Incidentally, this might reveal why some engineers struggle with things like UX, technology ethics, or algorithmic bias.)

I also have a mixed education of 1/2 CS and 1/2 Music. I found some of my music classes way harder (and often way more enjoyable) than many of my CS classes, despite the fact that the latter dealt with well-scoped problems.
