Unlocking the Secrets of Cambridge A Level Computer Science 9618 Paper 3 (P3) – June 2025

Introduction: Why P3 Matters More Than Ever

If you are preparing for the Cambridge International A Level Computer Science 9618 Paper 3 (P3) exam in June 2025, you are not just facing another exam — you are stepping into one of the most rewarding challenges of your academic journey.

P3 tests your deep understanding and practical application of some of the most powerful concepts in computer science. Covering Chapters 13 to 20, P3 examines everything from floating-point numbers to assembly language programming, from Boolean logic to artificial intelligence.

It demands mastery of knowledge (AO1) and application (AO2) — the two pillars Cambridge expects you to demonstrate. But here's the good news: with the right strategy and focus, P3 is not a mystery. It’s a system. And systems can be learned, mastered, and conquered.

This blog breaks down exactly how to do it — drawing on three years of real past paper analysis, prediction insights, and winning strategies. Let’s unlock the secrets together.

The Blueprint: What P3 Really Tests

Paper 3 is a structured theory exam — no practical coding, no program execution. Answers are given as formal explanations and structured pseudocode.

Key facts you must remember:

  • Low-level programming and Assembly are tested here, not in Paper 4.

  • Pseudocode is your language — knowing Cambridge's official style is critical.

  • Assessment Objective focus:

    • AO1 (Knowledge and Understanding) – 60%

    • AO2 (Application and Analysis) – 40%

AO3 (designing and programming) barely appears here — that's Paper 4's territory.
Conclusion: P3 rewards smart learners who are clear, organized, and methodical.

Past Paper Analysis: Trends You Cannot Ignore

A deep analysis of the past three years (June/Nov 2022–2024) shows:

  • Data Representation (Chapter 13) questions, especially floating-point formats, appear almost every time.

  • Boolean Logic and Circuits (Chapter 15.2) dominate — including truth tables, Boolean simplifications, and Karnaugh maps.

  • Network Protocols and Security (Chapters 14 & 17) are constant — covering TCP/IP, SSL/TLS, symmetric vs asymmetric encryption.

  • Algorithm Writing and ADT Operations (Chapter 19) are non-negotiable — queues, stacks, linked lists, often through pseudocode.

  • AI and Machine Learning (Chapter 18) are now regulars — mostly conceptual, occasionally algorithmic like A* searches.

  • Programming Paradigms (Chapter 20) rotate between OOP, Assembly, and Declarative (Prolog-style) logic — be ready for both.

Important: Cambridge does not ignore any chapter — they rotate emphasis, but nothing is off-limits.

Predictions for June 2025: What’s Coming?

Based on trends and syllabus focus, here's what you should prepare for:

High-Probability Topics

  • Floating-point normalization and errors

  • Boolean logic simplification and Karnaugh Maps

  • Network protocols (especially TCP/IP stack)

  • Cryptography and security comparisons

  • Pseudocode for standard algorithms (sorting, searching)

  • ADT manipulation (stack or linked list likely)

  • Assembly language snippet interpretation or writing

Medium-Probability Topics

  • OS Scheduling or Memory Management (paging, segmentation)

  • BNF and syntax diagram questions

  • Differences between RISC and CISC architecture

  • OOP concepts (inheritance, polymorphism)

Speculative (But Worth a Quick Look)

  • Exception handling basics

  • Machine learning examples in real-world contexts

  • A minor question on quantum cryptography

Warning: Ignoring Assembly Language and Declarative Logic could be a dangerous mistake — they could easily surface this year.

Winning Strategies: Before and During the Exam

Before the Exam

  • Revise Chapters 13–20 strategically, focusing most on 13, 15, 17, 19.

  • Master pseudocode — practice hand-writing algorithms until it feels automatic.

  • Practice past papers under timed conditions — spot your weak areas early.

  • Memorize key definitions and terms — Cambridge loves precise vocabulary.

During the Exam

  • Skim the paper first, allocate time wisely (~1 minute per mark).

  • Decode command words: State, Describe, Explain, Write Pseudocode — know the differences!

  • Attempt all questions — leave no blanks. Partial marks can save grades.

  • Use correct pseudocode style — Cambridge is strict about conventions.

  • Review answers carefully — especially long pseudocode or multi-step logic answers.

Final Words: Why You Can Beat P3

P3 is not a battle of genius; it’s a test of preparation.
Students who win are those who:

  • Break the syllabus into daily, achievable targets.

  • Think like examiners — writing exactly what is needed.

  • Stay calm and strategic throughout the exam.

You already have the roadmap.
Now it’s time to drive.

Believe in your preparation. Believe in the process. You are closer than you think to mastering Cambridge 9618 Paper 3.
