How we work this out

What it does

Every June Edexcel A-level Chemistry grade boundary from 2017 to 2026 as a percentage, and the 2027 exam dates.

Edexcel A-level Chemistry: the board's published June qualification boundaries from 2017 to 2026. No summer exams were sat in 2020 or 2021.

Method

  1. Each boundary is the published mark divided by the qualification's total marks that June.
  2. The range is the lowest and highest of those percentages across the years shown, rounded to the nearest whole percent.
  3. Where the board sets different boundaries for different option papers, each option has its own line.
