My son is a history major and is in the spring semester of his junior year. His college, while it does of course require that all students have a major, it does not require that the students have a minor.
He is feeling like he should have a minor since "everybody" has one and he does not. He has taken a number of electives but none so far have inspired him to want to persue that field for a minor (a minor would require 18 credits in a certain area).
I think that a minor isn't all that important since your diploma only notes your major and not your minor. When job hunting, I only applied for jobs that fit with my major and no one ever asked me what I minored in. My husband had the same experience when job hunting.
So, it is just fine to not have a minor? I'd appreciate hearing from others who have 'gone before us'.
