Bachelor of Medicine, Bachelor of Surgery (Latin: Medicinae Baccalaureus, Baccalaureus Chirurgiae; abbreviated in many ways, most commonly MBBS, but also MB ChB, BMBS, MB BCh, MB BChir and BM BCh), is the primary medical degree awarded by medical schools in countries that follow the tradition of the United Kingdom. The historical degree nomenclature states that they are two separate undergraduate degrees. In practice, however, they are usually combined as one and conferred together, and may also be awarded at graduate-level medical schools.
