Exam questions by topic for focused revision

The EduNinja Question Bank brings IB, A-Level, IGCSE and AP topic questions into one syllabus-based directory. Match your course, then choose a chapter, topic or learning objective instead of searching through questions from a different qualification.

Topic practice gives you a focused starting point when you know what needs work. Attempt a question without looking at the answer, then compare your response with the answer or mark scheme available for that question. Use what you missed to decide which idea to review next.

Choose an IB subject and SL or HL level, an AP course, or the CAIE or Edexcel branch for A-Level and IGCSE. The curriculum pages help you find a subject bank; the course and topic pages provide the questions for your selected syllabus.

Match the command term as well as the topic: a question asking you to describe needs a different response from one asking you to explain or evaluate. Compare the points in your answer with the guidance provided, then practise the reasoning you missed rather than memorising a model response.

How to use the question bank

  1. Choose your syllabus

    Match your curriculum, exam board, subject and available level to your school course. Open that question bank and choose the topic you want to revise.

  2. Attempt before checking

    Work through an available question and write down your answer or calculation. Then open the supplied answer guidance to compare the steps and points in your response.

  3. Review the gap and retry

    Return to the matching Notes or Course material when you miss an idea. Try another question on that topic, or use Practice or Diagnostic where available to continue your revision.
