Bachelor's degree
A bachelor's degree (from Middle Latin "baccalaureus") or baccalaureate (from Modern Latin "baccalaureatus") is an undergraduate academic degree awarded by colleges and universities upon completion of a course of study lasting three to seven years (depending on institution and academic discipline). In some institutions and educational systems, some bachelor's degrees can only be taken as graduate or postgraduate degrees after a first degree has been completed. In countries with qualifications frameworks, bachelor's degrees are normally one of the major levels in the framework (sometimes two levels where non-honours and honours bachelor's degrees are considered separately), although some qualifications titled bachelor's degrees may be at other levels (e.g. MBBS) and some qualifications with non-bachelor's titles may be classified as bachelor's degrees (e.g. the Scottish MA and Canadian MD).
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.
