Edexcel grade boundaries
Put in the marks you think you scored and see where they land against the boundaries Pearson actually published.
What grade is that?
Pick your subject, put in the marks you think you scored, and see where you land against the boundaries Edexcel actually published.
June 2024 boundaries. Grades move every session, and this uses a mark you’ve estimated yourself — treat it as a guide, not a prediction. IAL subjects use UMS and are being added.
How grade boundaries work
A grade boundary is the lowest mark that earns a given grade in a particular sitting. They are set after the exam, once examiners have seen how the cohort performed — which is why a paper everyone found hard ends up with lower boundaries than usual.
That is the single most useful thing to understand about them: boundaries move every session. A mark that was an A last June may be a B this year, or the other way round. Using an older session’s boundaries gives you a sensible ballpark, not an answer.
IGCSE and IAL work differently
IGCSE grades come straight from raw marks — score above the boundary, get the grade. That is what the calculator above does.
IAL uses UMS, the Uniform Mark Scale. Your raw mark first converts onto a standard scale that is recalculated each session, and the UMS totals across your units decide the final grade. It exists so that a unit sat in January and one sat in June count equally, but it means a raw mark on its own tells you less. IAL support is being added.
What this tool is not
It is a study aid, not a result. You are estimating your own mark, and only the examiner knows what you actually scored. Use it to see how far you are from the next grade and where to put your revision — not to decide anything important. Your school and Pearson are the authorities on your grades.
