Undergraduate degree
In the United Kingdom, a bachelor's degree is the most common type of "undergraduate degree". Some master's degrees can be undertaken immediately after finishing secondary education; however, these courses are usually extended versions of bachelor's degree programs, taking an additional year to complete. Most bachelor's degrees take three years to complete, with some notable exceptions, such as Medicine taking five years. Often students can initially enroll in a 4-year program then leave after three years and be awarded a bachelor's degree.
Graduate school
Although graduate school programs are distinct from undergraduate degree programs, graduate instruction (in the US, Australia and other countries) is often offered by some of the same senior academic staff and departments who teach undergraduate courses. Unlike in undergraduate programs, however, it is less common for graduate students to take coursework outside their specific field of study at graduate or graduate entry level. At the Ph.D. level, though, it is quite common to take courses from a wider range of study, for which some fixed portion of coursework, sometimes known as a "residency", is typically required to be taken from outside the department and college of the degree-seeking candidate, to broaden the research abilities of the student. Some institutions designate separate graduate versus undergraduate staff and denote other divisions.
