Bachelor's degree
Until the 19th century, a bachelor's degree represented the first degree in a particular faculty, with Arts representing undergraduate study, thus the Bachelor of Civil Law (BCL) at Oxford and the Bachelor of Laws (LLB) at Cambridge, for example, were postgraduate degrees. Vestiges of this system still remain in the ancient universities, with Oxford and Cambridge awarding BAs for undergraduate degrees in both arts and sciences (although both award undergraduate BTh degrees through associated theological colleges, and Oxford awards BFA degrees in addition to the BA) and defining other bachelor's degrees (e.g. BPhil, BCL) as postgraduate awards equivalent to master's degrees, although many postgraduate bachelor's degrees have now been replaced by equivalent master's degrees (e.g. LLM for the LLB at Cambridge and MSc for the BSc at Oxford). The same historical usage of indicating an undergraduate degree by it being in the faculty of arts rather than being a bachelor's degree gives rise to the Oxbridge MA and the Scottish MA).
Bachelor of Arts
A student who first achieves a general Bachelor of Arts degree with a sufficiently high overall average may be admitted to a "postgraduate" Baccalaureatus cum Honore degree in the same field; it requires a minimum of one year but may also take longer; it typically does not exceed two years. Students may be required to undertake a long high-quality research empirical thesis (Honours Seminar Thesis) combined with a selection of courses from the relevant field of studies. The consecutive B. cum Honore degree is essential if students ultimate goal is to study towards a two- or three-year very high research master's degree qualification. A student holding a Baccalaureatus Cum Honore degree also may choose to complete a Doctor of Philosophy (PhD) program without the requirement to first complete a master's degree. Over the years, in some universities certain Baccalaureatus cum Honore programs have been changed to corresponding master's degrees.
