Chemistry grade boundaries
Every Edexcel GCSE Chemistry boundary set we hold —4 awards across 2 series. Marks are raw marks for the whole subject, and every table links to the document it came from.
Grade 7 boundary over time
Shown as a percentage of the maximum mark, because the maximum changes when a board reforms a specification and raw marks stop being comparable.
