"Preferred qualifications for admitted OMS CS students are an undergraduate degree in computer science or related field (typically mathematics, computer engineering or electrical engineering) from an accredited institution with a cumulative GPA of 3.0 or higher. Applicants who do not meet these criteria will be evaluated on a case-by-case basis; however, work experience will not take the place of an undergraduate degree."[0]
So unless that other field is Math or computer-related, then that's not really going to work, which is why I specifically mentioned "another field".
