IGCSE Chemistry 0620 grade thresholds The raw marks needed for each grade in every recent series, copied from Cambridge's published tables. Latest: June 2026.
Find your option (the combination of papers you sat), then read across to the grade. Each series has its own thresholds, so use the table for the series whose papers you practise.

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
