All courses taken on study abroad must be for full credit and a grade. Courses may not be taken as an auditor/listener or on a pass/fail basis.
If you're a UD student, pay tuition and register for classes as you normally do.
If you're a student from another university, who has already completed the Biographic Info Form, go to your program's web page for course information. Send an email to the CFIS or FLL contact by the deadline, stating which courses you'd like to take. When you get back from overseas, remember to order a copy of your transcript from the UD Registrar's Office.
