How IGCSE Grading Works
From raw marks to grade boundaries to your final grade — the 9–1 and A*–G scales, Core vs Extended, and why boundaries move.
IGCSE Grades Explained: What Each Grade Means The 9–1 and A*–G scales side by side, what each grade signals, U/ungraded, tier caps, and the rough equivalences worth memorising.
What Is a 9 in IGCSE? (And How to Get One) The top grade in the 9–1 system, roughly what percentage it takes, how it compares to an A*, and how to realistically aim for one.
IGCSE Grade to Percentage: Why There Is No Fixed Number Why no grade equals a fixed percentage, how boundaries move it session to session, ballpark ranges, and how to find your subject's real figure.
What Is a Good IGCSE Grade? Passes vs strong grades, what sixth forms and universities actually look for, and a sane, plan-based way to judge your own results.
IGCSE Grade Boundaries Explained What boundaries are, why they change every session, when each series is released, and how to read a boundary table with a worked example.
How Predicted Grades Work for IGCSE What predicted grades are, who uses them, how teachers set them, and how to estimate your own from past-paper marks and real boundaries.
Core vs Extended: How to Choose Core protects your floor, Extended raises your ceiling. Real boundary differences, who should take which tier, borderline cases, and switching.
IGCSE vs GCSE: What Actually Differs? Boards, exam sessions, tiering, coursework and grading scales — the real differences, and why universities treat the two as equivalent.
IGCSE Results Day: What Happens & What to Do Release dates for each series, how statements of results work, what to check first, and your options if grades disappoint.
Remarks & Appeals: A Practical Guide Clerical re-checks vs reviews of marking, strict deadlines, costs and risks — and how to judge whether a remark is worth it.
