In an effort to keep this question generalizable, I'll try to be as vague as possible.
I'm majoring in a softer science (getting a BA), while doing research in a much harder science which could be considered a super-field to my major. This year, I did a year-long field project in my major field which counts toward a certain sociology minor that's at least somewhat related to my major. I'm interested in said minor and my planning said I could complete it, so I declared it.
However, certain circumstances mean that I wasn't able to complete minor-satisfying courses in a timely manner. If I want to get the minor, I have to stick around an extra quarter. I'm not sure that expense is really worth it to me just for the minor.
I intend to apply to grad school in the harder field, a field in which I have a paper or two and a presentation at a major conference.
How important is an unrelated minor in applying to grad school? Unlike something like music or a language, there's probably not much I could do with it, even in my personal life.
I read this question, but it's about minoring in a related field, not a distant field.
I've tagged this both
United States and
United Kingdom because I'm from the States but looking at a couple programs that would send me to the UK.
