If you are unhappy with the outcome of an examination you, or your College Tutor acting on your behalf, may be able to request a review of that outcome (particular criteria and strict deadlines apply). You can find out about the procedure for this at https://www.studentcomplaints.admin.cam.ac.uk/examination-reviews.
Higher Doctorates
There is no procedure in University regulations for appeal or review of decisions in respect of applications for Higher Doctorates; the decisions of the Postgraduate Committee and of the Degree Committees concerned are final.
