OCR H446 A-Level Computer Science Paper 2: 100 Algorithm Questions, Pseudocode & Model Answers

Stop searching for algorithm practice. This is the whole programme in one pack.

Algorithms and problem-solving is where A-Level students lose the most marks, and where teachers spend the most time writing resources from scratch. Algorithm Problem-Solving Mastery gives you 100 original, exam-style questions (673 marks) aligned to OCR H446 Component 02, with full model answers and a ready-made Teacher Edition. Print it, set it, mark it.

What’s inside

100 original questions in 7 sections: Computational Thinking, Algorithm Design, Searching & Sorting, Recursion & Iteration, Graphs & Shortest Paths, Algorithm Analysis & Efficiency, and Integrated Examination Challenges.
5 difficulty levels, from Foundation to Examination Mastery, so every student starts securely and finishes stretched.
A real mix of question types: flowcharts, trace tables, code completion, debugging, algorithm construction, worked calculations and extended 8-12 mark responses.
Full model answers with OCR-style pseudocode, trace tables, step-by-step reasoning, indicative marking points, common mistakes and alternative valid approaches.
Dijkstra’s and A*, with graph diagrams and fully worked tables. Also bubble, insertion, merge and quick sort, binary search trees, recursion, backtracking and Big O.
Final Algorithm Mastery Assessment: 4 questions, 30 marks, with mark scheme.

Teacher Edition extras
