If you have missed the date to defer/cancel your exam (6 weeks from the trimester start date), then you will need to re-register for the module when you wish to complete the exam. The re-registration fee is €180.

Alternatively, depending on the reasons, you may be eligible to apply for extenuating circumstances. You can view the extenuating circumstances policy and application form in the 'After the exams' section here: https://iob.ie/info/student-info#exams-and-regulations
