Edexcel International A Level Statistics grade boundaries

In short

Raw-mark grade boundaries for every Statistics unit of the Pearson Edexcel International A Level, from June 2025 to June 2026. Each unit is converted to a uniform mark scale (UMS); the overall grade comes from the total UMS.

Unit grade boundaries (raw marks)

International A Level units are graded on a uniform mark scale; the figures here are raw-mark boundaries for each unit, as published by Pearson. Use the source document for the conversion to uniform marks. Where a unit has more than one version in a series (for example 1 and 1A), each cell shows the lowest and highest boundary.
