OCR A-Level Computer Science Exam Dates 2027
Both A-Level Computer Science papers are sat in June 2027. These dates come from OCR's final (not provisional) timetable, so they will not move unless the exam board invokes its contingency plan.

Key facts
- Paper 1, Computer Systems (H446/01): Monday 7 June 2027, afternoon session, 1:30 pm – 4:00 pm. 2 hours 30 minutes, 140 marks, 40% of the A-Level. Covers specification sections 1.1 to 1.5.
- Paper 2, Algorithms and Programming (H446/02): Tuesday 15 June 2027, morning session, 9:00 am – 11:30 am. 2 hours 30 minutes, 140 marks, 40% of the A-Level. Covers specification sections 2.1 to 2.3.
- Programming project (NEA): 70 marks, 20% of the A-Level. Submitted through your school before the written papers; there is no exam for it.
- Contingency day: Wednesday 23 June 2027. Exam boards reserve this date in case of national disruption, so you must stay available until then.
- Eight days between papers. Plan Paper 2 revision (algorithms, programming, computational thinking) for the gap rather than trying to cover both papers at once in the final week.
