How to read these tables An option is the combination of papers a candidate sits. From 2026 Cambridge lists the papers instead of an option code. Overall thresholds use the weighted total out of the maximum shown, not the sum of raw paper marks. Component thresholds show how hard each paper was, but your grade comes from the overall total. A dash means that grade is not available for that option or paper. Practise for your target grade
