Co-majors are great options to add knowledge, experience and skills. When selecting a major and co-major, keep in mind a combination of what you like to do (your strengths and passions), what types of career you seek (your career goals), and what jobs are offered under each major / co-major (what the job market is like today and in the future).
A co-major means that you must select a “regular” full major in addition to one of the co-majors offered below. Co-majors are typically broader subjects that can provide targeted study to enhance your chosen major, and can also help to differentiate or brand you to recruiters. Co-majors add concentrated knowledge and strengths.
