Or is that something just engineers do?
No, I only had to take one. I took Chem waaaay back when I started community college because we thought we might have to persuade the school district I was still being edumacated, but it turned out since I was sixteen they didn't care.
Then I just ran out of time, I'd have had to take two maths and a physics class in the same semester. Plus my programming courses. I did think about doing it.
I took both chemistry and physics... couple of years on the chem side, and I was an accounting major.
I hated chemistry. Mostly because of the Rohr model. Really ticked me off, that. :-)
