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).
Education in the United States
Some students, typically those with a bachelor's degree, may choose to continue on to graduate or professional school, sometimes attached to a university. Graduate degrees may be either master's degrees (e.g., M.A., M.S., M.B.A., M.S.W.) or doctorate degrees (e.g., Ph.D., J.D., M.D., D.O.). Programs range from full-time, evening and executive which allows for flexibility with students' schedules. Academia-focused graduate school typically includes some combination of coursework and research (often requiring a thesis or dissertation to be written), while professional graduate-level schools grants a first professional degree. These include medical, law, business, education, divinity, art, journalism, social work, architecture, and engineering schools.
