    0478 Study Tips & FAQ

    What are paper variants?

    Cambridge releases multiple variants of each paper (e.g., Paper 11, 12, 13) to accommodate different time zones around the world and maintain exam security.

    Which variant you sit is set by your school's administrative zone: in the November 2026 timetable, for 0478, Variant 1 is sat in Zones 1 and 2, Variant 2 in Zones 3 and 4, and Variant 3 in Zones 5 and 6. Which zones sit which variant differs from subject to subject, so ask your exams officer which zone your school is in.

    All variants cover the same syllabus and have similar difficulty. Practice with any variant to prepare effectively for your exam.

    How to use Mark Schemes effectively

    Mark schemes show exactly how examiners award marks for each question. Understanding them helps you write answers that earn full marks.

    Tips:

    • Look for key words that must appear in your answer
    • Note how many points are needed for each mark
    • Understand the difference between "state" (brief) and "explain" (detailed)
    Understanding Grade Thresholds

    Grade thresholds show the minimum marks needed for each grade. They vary each session based on paper difficulty — harder papers have lower thresholds.

    How to use thresholds:

    • Set realistic target marks based on your goal grade
    • Track your practice paper scores against thresholds
    • Remember: you don't need 100% for an A* — aim for consistency
    • Compare thresholds across sessions to gauge difficulty trends
