Academic degree
Doctoral degrees or doctorates, such as the Doctor of Philosophy degree (PhD or DPhil) or Doctor of Education (EdD or DEd) are awarded following a programme of original research that contributes new knowledge within the context of the student's discipline. Doctoral degrees usually take three years full-time. Therefore, in the UK it may only take seven years to progress from undergraduate to doctoral level – in some cases six, since having a Master's is not always a precondition for embarking on a doctoral degree. This contrasts with nine years in the United States, reflecting differences in the educational systems.
Bachelor's degree
University admission is extremely competitive, with attendant advantages and disadvantages. Nonetheless, it takes four to five years to complete a bachelor's degree. In cases of poor performance, the time limit is double the standard amount of time. For example, one may not study for more than 10 years for a five-year course. Students are normally asked to leave if they must take longer. Nigerian universities offer B.Sc., B.Tech. (usually from Universities of Technology), B.Arch. (six years), and other specialized undergraduate degrees, such as B.Eng. Science undergraduate degrees may require six months or a semester dedicated to SIWES (Students Industrial Work Experience Scheme) but it is usually mandatory for all engineering degrees. A semester for project work/thesis is required, not excluding course work, during the bachelor thesis in the final year. The classifications of degrees: first-class, second-class (upper and lower), third-class (with honours; i.e., B.Sc. (Hons)) and a pass (no honours). First- and second-class graduates are immediately eligible for advanced postgraduate degrees (i.e., M.Sc. and Ph.D.), but other classes may be required for an additional postgraduate diploma before such eligibility.
