What is the acronym for a minor in a subject at a university?

I'm filling out a resume and need to list my education. For my bachelor's degree, it's just "B.S. Whatever", no problem.

I also have a minor. What is the acronym that I should use for this?

Solution 1:

If your minor is relevant to the job you're applying for, this site recommends this format:

B.Sc. Psychohistory; Minor: Library Science

There is no acronym or abbreviation necessary.

I have seen it written (more than once) as:

B. Sc. in Somethingorother, with a Minor in Somethingelse.

so I'd consider it correct, without any special acronym.
