It depends on what level of courses and how many courses you intend to take. Generally, applicants are encouraged to apply for the highest level admission status for which they qualify. If you only want to take a few courses, Gateway admission allows you to take up to 9 hours of credit (2-3 classes–graduate OR undergraduate level) at Dallas International. Graduate admission allows you to take an unlimited number of either undergraduate or graduate credit hours. Undergraduate admission allows you to take an unlimited number of undergraduate semester hours and also allows you to petition to take up to 9 semester hours of graduate-level study.
