AQA GCSE Computer Science 8525 Code Reading & Analysis Workbook | Trace, Debug, Predict, Grade 9

Stop losing marks on the questions students dread most — code they’ve never seen before.

Every AQA 8525 Paper 1 has them: unfamiliar code that students must trace, predict, debug and explain without ever running it. This is the single biggest skills gap in GCSE Computer Science and this workbook closes it, question by question, until it becomes second nature.

39 professionally formatted pages. 25 fully-resourced tasks. Zero prep required.

• 10 progressive sections Read the Code → Predict the Output → Trace the Variables → Complete the Code → Identify the Error → Explain the Algorithm → Debug the Code → Analyse the Logic → Compare Solutions → Grade 8–9 Code Analysis

• Full spec coverage — variables, data types, I/O, selection, iteration, nested loops, strings, lists, functions, Boolean logic, operators, validation, searching, sorting, testing and debugging, all in clean, exam-style Python

• A complete Grade 8–9 Code Reading Mastery Assessment 5 extended, multi-stage programs (46 marks) that stretch your highest attainers to genuine top-grade standard

• Every single task includes the code, structured questions with marks allocated using AQA command words, expected output, a full model answer, a clear explanation, an examiner-style mark scheme table, and a “Common Errors and Misconceptions” box that pre-empts exactly where students go wrong

• Built for real exam conditions students train to trace and reason on paper, with no computer needed, exactly as they’ll be tested

Whether you’re using it for lesson starters, homework, revision sessions or as a structured intervention for Paper 1, this workbook is ready to teach from the moment you open it no adapting, no writing your own mark schemes, no hunting for good practice code.

Give your students the one skill that separates a Grade 6 from a Grade 9: the ability to read code like an examiner does.
