Bachelor of Medicine, Bachelor of Surgery (Latin: Medicinae Baccalaureus, Baccalaureus Chirurgiae; abbreviated most commonly MBBS), 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. It usually takes five to six years to complete this degree.
