British undergraduate degree classification
In the United Kingdom, medicine is usually taught as an undergraduate course, with graduates being awarded a master's level qualification: normally the conjoined degrees of Bachelor of Medicine, Bachelor of Surgery (MBBS, BM BCh, MB ChB, etc.) although at Queen's University Belfast (and universities in Ireland) Bachelor in the Art of Obstetrics (BAO) is added, and at some universities only the Bachelor of Medicine is awarded - all of these have equal standing. Unlike most undergraduate degrees, the MBBS is not normally considered an honours degree, and thus is not classified into first class honours, etc. Students may be awarded "Merits" and "Distinctions" for parts of the course or the whole course (depending on the institution) and "Honours" may be awarded at some institutions for exceptional performance throughout the course (as a grade above Distinction).
British degree abbreviations
Primary qualifications in medicine, dentistry and veterinary medicine are taken as undergraduate-entry courses and are denominated bachelor's degrees, but are normally offered without honours These are also qualifications at the same level as postgraduate master's degrees, but retain the name of bachelor's for historical reasons. The Bachelors of Medicine and Surgery are always taken together as the primary medical qualification in the UK, equivalent to the American MD.
