School Levels · Secondary
We develop learners' skills in creative thinking, enquiry and problem solving — through the Cambridge IGCSE, the world's most popular international curriculum, and on to AS & A Levels.
The International General Certificate of Secondary Education (IGCSE) leads to globally recognised and valued Cambridge qualifications. It encourages learner-centred, enquiry-based approaches — excellent preparation for the next stage of education.
Students choose from a wide range of IGCSE subjects grouped into five curriculum areas:
Cambridge ICE Award
We encourage students to pursue the Cambridge International Certificate of Education (ICE): at least seven IGCSE subjects across the five areas, including two languages from Group I, one subject from each of Groups II–V, and seven passes (Grade A*–G).
AS & A Levels
Upon completing IGCSE, students further their studies at AS and A Levels for entry to universities across the globe — choosing core subjects across Sciences, Social Sciences and Mathematics over two years, with close supervision from our teachers and counsellors.
