What is Pre-International GCSE?

The Pre-International GCSE is an online programme developed for 12-14 year olds that provides a knowledge base for the academically rigorous International GCSEs. The programme is specifically designed for CGA by our teachers based on Pearson’s iLowerSecondary curriculum. There are two stages in the programme with Stage 1 serving as a foundation for Stage 2. Formative assessments prepare students for an internal examination at the end of the course.


The International GCSE classes course is suitable for students 12-14 years old. In some countries students divide studies over two years.


The Pre-IG courses can be taken as a full-time or part-time option along with other subjects. Students can also take a combination of levels at CGA.


Each stage of the Pre-IG course is a one-year class with an internal examination at the end of the course.
