Most general bachelors' degrees and many of the specialised bachelors' degrees have honours degrees associated with them (e.g. Bachelor of Arts and Bachelor of Arts with Honours). They usually require you to take extra papers in the subject of the degree and submit a research report or dissertation.
In most subjects, the honours degree is a postgraduate degree, requiring an additional year of study after you have completed a general three-year bachelor’s degree. In other cases (particularly professional programmes), the honours degree is an undergraduate degree requiring additional work but taking the same time as the corresponding ordinary degree.
You can undertake honours degrees in more than 1 subject, or to take a combined honours degree involving a blend of papers from 2 subjects.
