AS & A Level
Advanced Subsidiary (AS) qualifications are achieved after earning 1, 2 or 3 units (out of 2, 4 or 6, respectively) at GCE Level 3. They are commonly understood as the first year of the GCE A level. Students usually take a year to complete the AS and a further year for the A2 to complete the full A level qualification.
From September 2015, AS levels will be stand-alone qualifications and will no longer contribute to an A level grade.
A levels – sometimes called General Certificates of Education (GCE) or Advanced level – are normally studied after GCSEs or International GCSEs, but you can take them at any age. They mainly involve studying the theory of a subject combined with some investigative work, and are usually studied full-time over two years at school or college.To study a subject at A level, you’ll normally need to have studied it already at level 2 in a BTEC or GCSE.
