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.
Bachelor of Arts and Science
Bachelor of Arts and Science (B.A.S. or B.A.&Sc. or B.A.Sc.) is an undergraduate bachelor's degree conferred by a small number of American universities and a fair number of universities in other English-speaking countries (including Canada and Australia). Generally, to receive a B.A.S. degree, a student would need to complete the general requirements for a bachelor's degree and also the requirements for two different academic majors (or academic minors) — one that usually leads to a B.A. degree and one that usually leads to a B.S. degree. In the United States, the degree is meant to be a four-year degree, but many students will take five years to complete the program.
