OCR As Level Computer Science Paper 2 Question Paper

Download the official OCR AS Level Computer Science H046/02 Algorithms and Problem Solving question paper for the June 2025 examination series. This examiner-authentic OCR PDF contains the complete OCR AS Algorithms and Problem Solving paper covering arrays, searching, sorting, stacks, queues, pseudocode, software development methodologies and algorithm design.

The paper includes practical programming and computational-thinking questions based on gym-class booking systems, reusable program components, arrays, loops, searching algorithms, stacks, queues and pseudocode functions. Students are required to analyse, test and extend algorithms using structured problem-solving techniques and OCR-style pseudocode.

Programming tasks include rewriting while loops as for loops, outputting data from 2D arrays, insertion-sort trace tables, implementing linear-search functions, extending stack operations and designing algorithms using strings, arrays and validation. The assessment also covers binary search, bubble sort, black-box versus white-box testing and software-development methodologies including agile and waterfall.

Extended-response questions require evaluation of agile methodologies and the waterfall lifecycle within a team-based software-development scenario. Students must discuss benefits, drawbacks and real-world application of software-engineering approaches while demonstrating structured technical reasoning and computational understanding.

This OCR H046/02 June 2025 question paper is ideal for timed exam practice, mock examinations, pseudocode revision and OCR AS Computer Science preparation. It helps students understand OCR question structure, command words, mark allocation and examiner expectations for algorithms and problem-solving topics across the OCR specification.

Perfect for students preparing for the 2026 OCR examination series, teachers creating classroom assessments and tutors supporting OCR Computer Science revision. Pair this paper with the official OCR H046/02 June 2025 mark scheme for complete examiner-guided preparation and assessment practice. Fully compatible with desktop, tablet and mobile PDF viewing.

This document is designed for OCR AS Level Computer Science students preparing for the 2026 examination series, especially candidates studying algorithms, pseudocode and problem solving. It is particularly useful for learners aiming to improve computational thinking, programming accuracy, algorithm-tracing skills and understanding of OCR examiner expectations.

It is also highly valuable for teachers, tutors, revision-course providers and independent learners who require authentic OCR exam material for classroom assessment, timed coding practice, mock examinations, algorithm testing and targeted OCR Computer Science revision.
