OCR A-level Biology A H420: November 2020
Everything OCR publishes for the November 2020 series of H420: 9 files, grouped by the component they belong to. The board hosts every one of them; nothing on this page is a copy.
Checked against OCR’s own listing on 31 August 2026.
There was no June 2020 series. The summer exams were cancelled and an autumn series was sat in their place, so this is the 2020 paper.
The 2020 series was held in November rather than June.

Every sitting of H420 examines the same structure; what changes is the questions. The H420 past papers page has the whole list of series, and the OCR Biology A specification map says which headings this library teaches.
