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
A Bachelor of Arts is entitled to the designation B.A. for an ordinary/pass degree and B.A. (Hons) for an honours degree. Students who completed an honours B.A. sometimes style themselves by '(Hon)' or '(Hons)' after the degree abbreviation in parentheses. An honours degree is always awarded in one of four classes depending upon the marks gained in the final assessments and examinations. The top students are awarded a first-class degree, followed by an upper second-class degree (usually referred to as a 2:1), a lower second-class degree (usually referred to as a 2:2), and those with the lowest marks gain a third-class degree. An ordinary or unclassified degree (which does not give the graduate the right to add '(Hons)') may be awarded if a student has completed the full honours degree course but has not obtained the total required passes sufficient to merit a third-class honours degree. Typically these degrees lack the last year requirement of a dissertation.
