In the United Kingdom, the degree of bachelor is the most common type of "undergraduate degree", even when some master's degrees can be undertaken immediately after finishing secondary education (but the latter would not be considered as undergraduate degrees); however, these courses are 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.
