I was a music history major, and we had to take 2 math courses, and one had to be Acoustics, which we were all afraid of, and waited until we were seniors to take it, and then it turned out to be pretty easy. I ended up working for a classical record label, and used my acoustics knowledge pretty often during recording sessions. I became the guy they talked to about acoustic treatments in the recording halls and such. We even switched recording halls, when I figured out that the hall sounded better when there were pillows in the seats to simulate people. I got an A in that class.
The other math class I took was Statistics. I was terrible in Math during high school, and barely survived Algebra 2. I was not looking forward to more of that, and statistics sounded like it had a real-world use that I could understand, and I was right. I could understand the math because it had a reason that I could see, unlike the abstract nature of most math. I got a B in Statistics, which I was really proud of.
I still use my statistics knowledge to this day, whenever one party or another starts crowing about a new poll, and I see that it had a tiny sample size, and a margin of error of 5%+, and it is essentially useless poll.
