It was launched as part of British educational reforms in the 1950s along with the more in detail and academically thorough A-level (Advanced Level) in England, Wales and Northern Ireland. England, Wales and Northern Ireland swap O-levels with GCSE and IGCSE exams in 1988. The Scottish equivalent was the O-grade (replaced, following a part process, by the Standard Grade). O Level directs to globally recognized qualifications, acknowledged by leading universities and employers worldwide as verification of academic skill. Assessment takes place at the end of the course and comprises written, oral and practical examinations. This offers students a diversity of ways to demonstrate their knowledge and skills, principally when their first language is not English. Grades are bench marked using six globally recognized grades, from A* to E, which have apparent guidelines to clarify the standard of achievement’s Level examination series come about twice a year, in June and November for Cambridge. They are academic courses which engross rigorous independent reading, thinking and essay writing. Students, who select subjects they like, are the ones who get the most out of studying A levels.
