Is IGCSE the British curriculum?

IGCSE is the international version of the British GCSE curriculum. It follows the same academic standard but is designed for students outside the UK, with content that's culturally and linguistically international.

How is IGCSE different from GCSE?

GCSE is taken by students in UK state schools; IGCSE is taken worldwide. IGCSE is graded A*–G (or 9–1 in Edexcel), assessed mostly by final exams, and accepted by universities everywhere — including all UK universities.

Is IGCSE harder than KCSE?

IGCSE and KCSE are different systems, not directly comparable. IGCSE is subject-flexible, exam-focused, and internationally recognised. Many Kenyan families choose IGCSE for the direct route into UK, US, Canadian, Australian and European universities.

Can you take IGCSE online?

Yes. Accredited online schools like Brainybay deliver the full Cambridge IGCSE curriculum with live teachers, small classes and formal exam registration at approved centres worldwide.
