A bachelor's degree is the highest level of undergraduate degree and can typically be completed in four years, depending on the institution. Bachelor's degrees cover a particular discipline of your choosing and consist of a mixture of required general education courses, program-specific courses and electives.
Bachelor's degrees are typically categorized as either a Bachelor of Science (BS or BSc) or a Bachelor of Arts (BA). There are additional bachelor's degree classifications, such as a Bachelor of Fine Arts (BFA), but these tend to be more highly specialized to a particular field.
