GCE Mathematics builds on the skills, knowledge and understanding that students have developed in their previous study of mathematics up to GCSE level. A study of GCSE Additional Mathematics is beneficial but is not a requirement.

Students with a qualification in GCE Mathematics have experienced success in further and higher education as well as careers in accountancy, finance, statistics, computer programming, engineering, medicine, psychology, dentistry and teaching among others.
