MPhil and PhD are research degrees and are awarded after the examination of a candidate's thesis, produced following a period of research. While most candidates pursue research degrees on a full-time basis, in certain circumstances it is possible to offer them on a part-time basis. You may register for these degrees at the beginning of any month. The usual period of registration for research degrees is:Full-time: MPhil 2 years / PhD 3 years, Part-time: MPhil 3 years / PhD 5 yearsIt is possible for you to complete the MPhil after studying for only one year full-time or two years part-time. If you are a PhD candidate with a relevant Master's degree or at least two years' relevant experience, your period of registration could possibly be of only two years' duration full-time or three years part-time. This arrangement would have to be agreed by your Head of Department and Supervisor before your research is started. We expect PhD students to produce and submit a thesis for examination within four years of starting a three-year programme.
