 Edexcel and Cambridge International Examinations (CIE) are examination boards which offer the IGCSE qualification worldwide.Students generally take five to ten subjects, according to their desired program of study and the offerings available at their school; an IGCSE with eight subjects at grades A*-C is considered equivalent to the full high school diploma.Unlike the high school diploma, which is typically studied for in grades 9-12 (years 10-13 in the UK) and awarded in grade 12 (year 13), the IGCSE is typically awarded at grade 10 (year 11 in the UK), after which the A Levels are studied for and awarded.
