When students get into the upper grades in both US and British schools there are other differences. In most cases, the US students continue on with a broad, liberal arts education with some choices that are of particular interest to the learner, but not a concentration in a specific area. In British education learners pick areas they want to concentrate on with the General Certificate of Secondary Education (GCSE) or International General Certificate of Secondary Education (IGCSE) if outside of the United Kingdom. With the GCSE and IGCSE learners choose their subjects and study them for two years. They then take an exam and receive a certificate and have now completed their compulsory education. Some will then go into university while many others will stay in school for another two years and either do the International Baccalaureate’s Diploma Programme (DP) or A Levels and then go off to university. During these years in the US math and science are usually taught as independent and sequential subjects such as Algebra, Geometry, Calculus, etc. and Biology, Chemistry, Physics, etc. while in a British education system they are taught simultaneously. In the US learners’ grades are cumulated together to form a grade point average, GPA, while in British schools the learners receive their marks for completion of the GCSE or IGCSE and if they remain in school for the DP or A Levels.
