Search Algorithms Exam - GCSE Computer Science

40 exam-style questions on linear and binary search, with a live streak and timer — built to drill the O(n) vs O(log n) distinction that trips students up on Paper 2.
Full description:
Linear and binary search look simple until an exam question asks students to justify why binary search is faster, or to trace through a search on a specific list — and that’s exactly where marks get lost. This exam-style game covers both algorithms in depth, including their step-by-step mechanics and their efficiency, with a streak-and-timer format that pushes students to answer quickly and confidently rather than second-guessing.
• 40 auto-marked exam-style questions covering linear search and binary search
• Tests both algorithm mechanics (how each search works, step by step) and efficiency (O(n) vs O(log n) reasoning)
• Live streak and timer mechanic keeps pace high and rewards consistent accuracy, not just single correct answers
• Instant feedback with a full explanation for every question
• Runs as a single HTML file: no login, no install, works on any school device
Use it as timed retrieval practice before a Paper 2 mock, a starter to sharpen recall at speed, or independent revision homework on algorithm efficiency.
