Basically, your major is where MOST of your coursework will be focused & should ultimately help you in your career path. Minors (Some schools call them Concentrations.) are often unnecessary, but can sometimes be useful…For example, if you have a broad major like Business Administration, but you want to work in Advertising then you might minor in Marketing, but at some schools you might be better off to major in Marketing, IF you’re certain that’s what you want to do. Another reason for a minor is to show versatility…someone majoring in English who’s good with computers might minor in Computer Science or CIS. (This scenario would also work the other way around.) I have a friend who just graduated & although she majored in Elementary Education, she minored in Spanish, because she knows that Spanish is a marketable skill in the US today.
