The document outlines assessment structures and contrasts Paper 1 and Paper 2 content, covering programming, computational thinking, networks, security, data representation, algorithms, and SQL-related topics. It highlights key topic changes, specifying what learners will no longer need to teach in J277 and what must be taught in AQA 8525, including file handling, testing types, IDE features, Huffman coding, and additional computer systems concepts.","Switching to AQA GCSE Computer Science from Cambridge OCR  \nThis guide compares our GCSE Computer Science (8525) specification with the Cambridge OCR Level 1/Level 2 GCSE (9-1) in Computer Science (J277) to help you make the right choice for your learners. At the end of the document, you will find links to further support and helpful resources.  \nAssessment structure Option/entry codes  \n\n| AQA GCSE Computer Science | Cambridge OCR GCSE Computer Science |\n| --- | --- |\n| 8525A (C\\#), 8525B (Python), 8525C (VB.NET) 8525/1A, B or C | J277 |\n\nPaper 1  \n\n| AQA GCSE Computer Science | Cambridge OCR GCSE Computer Science |\n| --- | --- |\n| Title: Computational thinking and programming skills | Title: Computer systems |\n| Assesses computational thinking, code tracing, problem-solving, programming concepts including the design of effective algorithms and the designing, writing, testing and refining of code | Assesses systems architecture, memory and storage, computer networks, connectionsand protocols, network security, systems software, ethical, legal, cultural and environmental impacts of digital technology |\n| Written paper: 2 hours\u003Cbr>90 marks\u003Cbr>50% of GCSE | Written paper: 1 hour and 30 minutes 80 marks\u003Cbr>50% of GCSE |\n| Mix of multiple choice, short answer and longer answer questions assessing programming, practical problem-solving and computational thinking skills\u003Cbr>Learners answer questions using one of the following: C\\#, Python (version 3), VB.NET | Mix of multiple choice, short answer and longer answer questions assessing programming, practical problem-solving and computational thinking skills |\n\nPaper 2  \n\n| AQA GCSE Computer Science | Cambridge OCR GCSE Computer Science |\n| --- | --- |\n| Title: Computing concepts | Title: Computational thinking, algorithmsand programming |\n| Assesses data representation, computer systems, computer networks, cyber security, relational databases and SQL, ethical, legal and environmental impacts of technology | Assesses algorithms, programming fundamentals, producing robust programs, Boolean logic, programming languages and Integrated Development Environments |\n| Written paper: 1 hour 45 minutes 90 marks\u003Cbr>50% of GCSE | Written paper: 1 hour and 30 minutes 80 marks\u003Cbr>50% of GCSE |\n| Mix of multiple choice, short answer, longer answer and extended response questions assessing SQL programming skills and theoretical knowledge | Two sections\u003Cbr>In Section B, questions answered using either the Cambridge OCR Exam Reference Language or any high-level programming language |\n\nSummary of key differences  \nThe following tables give a high-level summary of some key differences between the two qualifications.
