We offer both GCSE and IGCSE Science courses. Both are excellent qualifications, but there is an important difference in their practical assessment requirements, particularly for students who are home educated or studying independently.
Before you start, check that you can complete the required practicals. Ask your exam centre:
This applies to every GCSE Science in England, not just AQA, because it is a national rule for GCSE Sciences.
Brainy Lemons Recommendation: Choose Pearson Edexcel IGCSE if you are home educated or sitting the exam as a private candidate.
Every lesson, quizzes, progress tracking, custom timetables and fun games.
