Chemistry grade boundaries

Every OCR GCSE Chemistry boundary set we hold —31 awards across 8 series. Marks are raw marks for the whole subject, and every table links to the document it came from.

Shown as a percentage of the maximum mark, because the maximum changes when a board reforms a specification and raw marks stop being comparable.
