How we work this out
What it does
Every June Edexcel GCSE Chemistry grade boundary from 2018 to 2026 as a percentage, and the 2027 exam dates.
Edexcel GCSE Chemistry: the board's published June qualification boundaries from 2018 to 2026. No summer exams were sat in 2020 or 2021.
Method
- Each boundary is the published mark divided by the qualification's total marks that June.
- The range is the lowest and highest of those percentages across the years shown, rounded to the nearest whole percent.
- Where the board sets different boundaries for different option papers, each option has its own line.
