The real papers
OCR sets two papers, each 1 hour 30 minutes, 80 marks and half the GCSE.
Paper 1 (J277/01), Computer systems, covers systems architecture, memory and storage, networks, network security, systems software and the wider impacts. Paper 2 (J277/02), Computational thinking, algorithms and programming, has Section A on algorithms, programming, Boolean logic and languages, and Section B, where you write, refine and test code in OCR Exam Reference Language or a high-level language such as Python.
