IGCSE, A Level, IB & GCSE Grade Predictor

Pick your subject from the directory below — each subject has its own dedicated predictor page with the right paper structure, mark totals and historical grade boundaries pre-loaded. On the subject page, enter your mock or practice marks for each paper. The tool combines them, compares against the historical average boundaries (2019–2024), and tells you your predicted grade with a confidence level plus the exact marks needed for the next grade up.

Predictions are based on historical average grade boundaries from official board publications across six recent May/June series (2019–2024). Actual boundaries vary each year — typically by ±5–15 marks depending on subject. Use the prediction as a guide for revision planning, not a guarantee of your final grade.

Yes — on each subject's predictor page you can enter marks for the papers you've sat and leave the rest blank. The tool scales your total proportionally to the full paper total and shows a partial-prediction warning so you know it's an estimate.

"Likely" means your mark is comfortably above the historical average boundary — within the typical year-to-year variation. "Possible" means you're in the range but could shift if boundaries move. "Borderline" means you're very close to the boundary and could go either way.

The Grade Boundary Tracker tells you what grade a specific mark corresponds to in a specific year. The Grade Predictor takes marks from multiple papers, combines them across the full qualification, and gives you a forward-looking prediction with marks-to-next-grade guidance.
