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).
Academic dress of the University of Cambridge
A graduand (someone about to be presented for a degree) wears the full Cambridge academic dress of the highest status degree that they already hold. Graduands who do not already hold a Cambridge degree wear the gown appropriate to their status in the University, along with hood of the degree to which they are about to be admitted. Undergraduates, who do not yet hold a degree, wear their undergraduate gown, with the hood of the degree that they are about to receive. Thus, for example, an undergraduate graduating to a BA degree wears an undergraduate gown and a BA hood. A holder of a BA from Cambridge graduating to a PhD wears both a BA hood and gown, whereas a graduate of another university graduating to a PhD wears a BA or MA status gown and PhD hood.
