The General Certificate of Secondary Education (GCSE) is the name of a set of British examinations, usually taken by secondary school students at age 14–16 in England, Wales and Northern Ireland (but not Scotland, where the equivalent is called Standard Grade).
GCSE was introduced for teaching in September 1986, and replaced both the O-level GCE (Ordinary level General Certificate of Education) and the CSE (Certificate of Secondary Education) qualifications, which suffered problems due to the two-tieredness of the system.
Introduced in 2000 was the Vocational GCSE, which encouraged students to take the work-related route and included courses such as engineering, applied business, ICT and leisure and tourism.
GCSE courses can be started at any time to suit you, and contain about 100 hours of study.
Biology is a fascinating subject, and by taking this GCSE you'll not only gain a valuable insight into the role of humans, plants and animals in the environment, but also give yourself a head start when it comes to working in the field of science.
