A Bachelor of Science (Bc., B.S., BS, B.Sc. or BSc; less commonly, S.B., SB, or Sc.B. from the Latin Scientiæ Baccalaureus) is an undergraduate academic degree awarded for completed courses that generally last three to five years (see below).

In Australia, the BSc is a 4 year degree, offered from 1st year on. A fifth (Honours) year or an MSc is then required to progress on to PhD.

Many universities in Europe are changing their systems into the BA/MA system, and in doing so also offering the full equivalent of a B.Sc. or M.Sc.

Commonly in the Commonwealth and Ireland graduands are admitted to the degree of Bachelor of Science after having completed a programme in one or more of the sciences. These programmes may take different lengths of time to complete.

A Bachelor of Science receives the designation B.Sc. or B.S. for a major/pass degree and B.Sc. (Hons) or B.S. (Hons) for an honours degree. In England, Wales and Northern Ireland an honours degree is typically completed over a three year period, though there are a few intensified two year courses (with less vacation time). In Scotland, where access to university is possible after one less year of secondary education, degree courses have a foundation year (simply known as the First year) making the total course length four years. In Ireland the former B.Sc. was changed to B.Sc. (Hons.) which is awarded after 4 years. The B.Sc. (Ord.) is awarded after 3 years^{[citation needed]}.

Richard Terfry (born March 4, 1972), who uses the stage name Buck 65, is a Canadian experimental artist, MC and turntablist. Underpinned by an extensive background in abstract hip hop, his more recent music has extensively incorporated blues, country, rock, folk and avant garde influences.

Terfry is also a radio host, hosting the weekday Radio 2 Drive show on CBC Radio 2 since September 2, 2008. In addition, he once hosted a weekday program on CBC Radio 3's web radio station.

Terfry was born in 1972 and raised in Mount Uniacke, Nova Scotia, a rural community 40 km north of Halifax. He was first exposed to rap music in the mid-1980s while listening to CBC Stereo's late night show Brave New Waves, and then by listening to Halifax campus community radio station CKDU. CKDU then broadcast at only 33 watts, and he had to climb a tree in his yard to hear the station's hip hop show on his radio. Fascinated by hip hop, the young Terfry taught himself how to rap, DJ, and, later, to produce records. His musical influences include MC Shan, David Lynch, Gitche Manitou and Kool Keith.
