Common questions
Where can I find Computer Science past papers from OCR?
This page links every Computer Science 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 Computer Science papers?
Yes, 10 of the 13 question papers here have a mark scheme, and 10 have an examiner report as well, which is worth reading for the mistakes that cost the most marks.
What were the Computer Science grade boundaries in June 2026?
In June 2026, an A needed 254 out of 350 and an E needed 104. 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 Computer Science specification?
It is linked at the top of this page: OCR's own Computer Science specification (H446), 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 4 papers, worth 420 marks in all.
How can I practise more Computer Science 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 Computer Science?
Cookie Tutoring may have tutors for Computer Science. 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.
