Will taking a course pass/fail affect me down the line? (already accepted into MS)

[making_waves]

I’m a undergrad civil engineering major in my last semester. I’ll be going for my master’s after graduation. After my masters there’s a good chance I’ll go on to a PhD at another institution, potentially in Europe (if that matters).

I’m currently debating whether or not to take an intermediate CS class pass/fail. At the graduate level, my subfield is fairly computational, despite undergrad civil curricula not being so. While not required for my major to graduate, I thought it’d be nice to get a little more CS experience to prep myself.

I’d prefer to take the course pass/fail since it’s quite difficult and my life is a bit busy with research/work. The grading is a bit hard to predict, but I might end up with anywhere between a B- to an A I think.  Would any graduate schools down the line care about this as I apply to PhD programs? It’d be the only pass/fail course on my transcript and I otherwise have a 4.0 GPA. While not a major requirement or a course most civil undergrads take, it’s still relevant to my field so I feel like it’s a grey area.

Idk if I’m overthinking this, but I’ve gotten this far and just want to choose wisely. Basically, would a pass/fail course or a potential B be better, or does this even matter?
