2025 Pearson Edexcel GCSE Computer Science Paper 2 and Mark Scheme Combined (1CP2/02: Application of Computational Thinking)

Paper 2 is the Application of Computational Thinking component of the Pearson Edexcel GCSE Computer Science qualification (1CP2/02). This paper assesses students’ ability to apply computational thinking skills, including problem-solving, algorithm design, and programming concepts, in practical scenarios.

It complements Paper 1 (1CP2/01: Principles of Computer Science) and forms 50% of the total GCSE Computer Science grade.

✔ What the Paper Covers

Paper 2 focuses on the following areas:

🧠 Computational Thinking and Problem-Solving

Analysing problems and identifying computational solutions
Designing algorithms, including pseudocode and flowcharts
Decomposition, abstraction, pattern recognition, and logic

💻 Programming Concepts

Writing and interpreting code in a high-level programming language
Understanding variables, data types, operators, and control structures
Functions, procedures, and subroutines
Input, output, and error handling

📊 Data Representation and Manipulation

Arrays, lists, and other data structures
Searching and sorting algorithms
Handling and processing data efficiently

📋 Application and Evaluation

Applying computational thinking to solve real-world problems
Evaluating the effectiveness and efficiency of algorithms
Debugging and testing solutions

✔ Structure of the Paper

Short-answer questions testing knowledge and understanding of algorithms and programming
Scenario-based questions requiring application of computational thinking
Extended-response questions including algorithm design, pseudocode, flowcharts, or evaluation of solutions

The paper assesses the following skills:

AO1 – Knowledge and understanding of programming and computational thinking concepts
AO2 – Application of knowledge to practical problem-solving tasks
AO3 – Analysis and evaluation of solutions, efficiency, and correctness

✔ Mark Scheme (Included in the Combined Document)

The combined question paper + mark scheme includes:

Model answers and accepted solutions for short and extended questions
Guidance on marking pseudocode, flowcharts, and programming tasks
Allocation of marks for problem-solving, algorithm design, and evaluation
Examiner notes to ensure fair and consistent marking

The mark scheme emphasizes logical reasoning, correct application of computational thinking, and clarity in solution design.
