Graduate students register first, then seniors, etc.
By the time freshmen register it is usually difficult to get into some of the classes they want and class schedules reflect the necessity to take what is left. Honors students are allowed priority registration because it would be virtually impossible to arrange their schedules around the required Honors courses without it. Because priority registration is such a prized commodity, there are eligibility requirements that must be met. You must be taking an Honors course in the semester during which you are registering, and, if you are a first-semester freshman, you must be requesting an Honors course for the semester for which you are registering. Thereafter you must be only be registered for an Honors course when you are registering for the next semester.
