YES. All courses taken in Canberra count towards the ANU graduation requirements. Therefore, failing any course(s) will affect your ANU degree. You should contact and communicate with the ANU CAP Student (cap.student@anu.edu.au) and BAPA (bapa.bell@anu.edu.au) regarding ANU courses and ANU graduation requirements.
If you have inquiries about RU graduation requirements, contact GLA Academic Advisors via the General Inquiry Form or make an appointment with them via the Advising Appointment Request Form.
