The series either side
June 2018, the series after. June 2017 is the oldest series OCR lists for H420.
Every sitting of H420 has the same structure. Only the questions change. The H420 past papers page lists every series, and the OCR Biology A specification map shows which headings we teach and where.
We checked these links against the exam boards’ websites on 31 August 2026. We do not host or reproduce past papers or mark schemes. If a link has moved, go to the board’s own past papers page.
