In college, B.S. stands for "Bachelor of Science" and refers to one of the many types of undergraduate, four-year degrees that students can earn. A B.S. program includes courses in liberal arts, sciences and mathematics, and partially covers general education coursework as part of its curriculum.
Coursework that is required to attain a B.S. degree can be divided into core coursework classes and general education classes. Core coursework classes depend largely on the major chosen by the student. An engineering major, for example, requires engineering courses as a pre-requisite to graduate. General education classes can cover a wide variety of topics, such as economics or psychology, and are typically taken during the first two years of a four-year B.S. program.
