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).
Bachelor's degree
Bachelor's degrees may take either three or four years to complete and are awarded by colleges and universities. In many universities and colleges bachelor's degrees are differentiated either as bachelor's or as honours bachelor's degrees. The term "Honours" is an academic distinction, which indicates that students must achieve their bachelor's degree with a sufficiently high overall grade point average; in addition, some programs may require more education than non-honours programs. The honours degrees are sometimes designated with the abbreviation in brackets of '(Hon(s))'.
