If you have a complaint about some aspect of your studies, or if you have not been awarded the degree you sought and wish to appeal against the judgment, you should refer to the University's Student Complaints and Appeals website, which gives full details of the procedure as well as important background information.
Your Department should provide you with details of the local Responsible Officer to whom complaints can be raised in the first instance.
