Postgraduate courses are any courses at a level above undergraduate, such master’s degree or Ph.D. courses. Depending upon the postgraduate degree sought, courses derive from disciplines similar to any that occur during an undergraduate degree program, such as math, science, arts and humanities, although the distribution of requirements according to discipline is slightly different.
In a typical breakdown of curriculum, a course level number distinguishes postgraduate courses from undergraduate courses. At many postsecondary institutions, undergraduate course numbers fall between one and 499, with postgraduate courses beginning at 500.
