Students may complete postgraduate study programmes at both Masters and Doctorate levels, across all areas of general study. A typical Masters degree for a full-time student is one-two years in length, whilst a PhD may take between two-five years to complete. Specific requirements, course and credit options for postgraduate programmes varies between institutions more significantly than undergraduate studies, and should always be researched thoroughly and confirmed directly with host and home departments. Postgraduate study takes a deeper, more specialised focus upon a field of study than in undergraduate, and so students should be more decisive about their subject choices.
