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BCL) as postgraduate awards equivalent to master's degrees, although many postgraduate bachelor's degrees have now been replaced by equivalent master's degrees (e.g. LLM for the LLB at Cambridge and MSc for the BSc at Oxford).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).
Undergraduate degree
First professional degrees sometimes contain the word "Doctor", but are still considered "undergraduate degrees" in most countries, including Canada. For example, the Doctor of Medicine (M.D.) program in Canada is considered an "undergraduate degree." However, in the United States, most first professional degrees are considered graduate programs by the U.S. Department of Education and require students to already possess an "undergraduate degree" before admission. These degrees are not research doctorates and are therefore not equivalent to the Doctor of Philosophy (Ph.D.) Many countries offer bachelor's degrees that are equivalent to American graduate degrees. For example, the Doctor of Medicine and Doctor of Osteopathic Medicine degrees offered in the U.S. are equivalent to the Bachelor of Medicine and Surgery (MBBS or MBChB) degree.
