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BCL) as postgraduate awards equivalent to master's degrees, although many postgraduate bachelor's degrees have now been replaced by equivalent master's degrees (e.g. LLM for the LLB at Cambridge and MSc for the BSc at Oxford).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).
British undergraduate degree classification
Regulations governing the progression of undergraduate degree graduates to postgraduate programmes vary among universities, and are often flexible. A candidate for a postgraduate master's degree is usually required to have at least a 2:2 bachelor honours degree, although candidates with 2:1s are in a considerably stronger position to gain a place in a postgraduate course and to obtain funding, especially in medical and natural sciences. Some institutions specify a 2:1 minimum for certain types of master's program, such as for a Master of Research course.
