Medicinæ Baccalaureus & Baccalaureus Chirurgiæ (MB BChir or MB ChB or MBBS or variations thereof) are the two degrees awarded after a course in medicine at a university in the United Kingdom and other places following the British tradition. In theory they are two separate degrees, but in practice the two are usually treated as one.
The MBBS is usually an undergraduate degree that requires five or six years of undergraduate study. Graduates are entitled to use the title Doctor and are elegible for membership of professional institutions such as the Royal College of Physicians.
