Common questions
Where can I find Biology A past papers from OCR?
This page links every Biology A paper OCR publishes for everyone to download, newest first, starting with June 2025. Each link opens the PDF on OCR's own website. The most recent series is usually released a year or so after the exam, and it will appear here once OCR makes it public.
Are there mark schemes for these Biology A papers?
Yes, 24 of the 30 question papers here have a mark scheme, and 23 have an examiner report as well, which is worth reading for the mistakes that cost the most marks.
What were the Biology A grade boundaries in June 2026?
In June 2026, an A needed 176 out of 270 and an E needed 72. The grade boundaries for every series from June 2017 to June 2026 are on this course's grade boundaries page, and each series of papers here links to its own year's table, so you can mark a paper and read your grade.
Where is the Biology A specification?
It is linked at the top of this page: OCR's own Biology A specification (H420), a PDF on its website, which sets out what you can be examined on and how the exams are marked. According to OCR's grade boundaries for June 2026, the course is examined in 3 papers, worth 270 marks in all.
How can I practise more Biology A questions?
Once you have worked through the papers, cookie has a practice deck for this course with fresh questions based on the specification and past papers, feedback on what you write, and spaced repetition.
Can I get help with Biology A?
Cookie Tutoring may have tutors for Biology A. The Find a tutor link keeps the subject and qualification filters from this page, so you can check the marketplace without assuming that a suitable tutor is available.
