I initially planned to double major in math and computer science, but in order to do that I'd have to spend an extra year at college. My main interest is definitely in computer science. I either want to go to graduate school or get a job as a software engineer. Would double majoring in math and computer science be beneficial or a waste of a year? Well, I know it won't exactly be a "waste" but would it look better to prospective employers and grad schools?
