Students can work towards a first degree at either ordinary or honours level. A general or ordinary degree (BA/MA or BSc) takes three years to complete; an honours degree (BA/MA Hons or BSc Hons) takes four years. The ordinary degree need not be in a specific subject, but can involve study across a range of subjects within (and sometimes beyond) the relevant faculty, in which case it may also be called a general degree; if a third year or junior honours subject is included, the ordinary degree in that named discipline is awarded. The honours degree involves two years of study at a sub-honours level in which a range of subjects within the relevant faculty are studied and then two years of study at honours level which is specialised in a single field (for example classics, history, chemistry, biology, etc.). Not all universities in Scotland adhere to this, in some you study in several subjects within a faculty for three years and can then specialise in two areas and attain a joint honours degree in fourth year.
