Biology grade boundaries
Every AQA A-level Biology boundary set we hold —3 awards across 3 series. Marks are raw marks for the whole subject, and every table links to the document it came from.
Grade A 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.
