Study Tips

  1. 1

    Review required practicals and data-analysis skills — experimental questions appear on nearly every paper.

  2. 2

    Make concept maps connecting topics — modern exam questions frequently cross unit boundaries.

  3. 3

    Draw and label diagrams for every major process — reproducing them from memory is a powerful test of understanding.

  4. 4

    Review class notes within 24 hours of each lesson — quick review dramatically improves retention.

  5. 5

    Use homework as diagnostic practice: redo any problem you got wrong until it feels easy.

Past Exam Questions

MediumMeasures of Disease Frequency2023

Define Measures of Disease Frequency and state the key facts a student must know, using precise scientific terminology.

HardStudy Designs2022

Explain the mechanism behind Study Designs: describe what happens and, crucially, why it happens. Include a labelled diagram where appropriate.

MediumCohort & Case-Control Studies2024

Design an experiment (or interpret given data) to investigate Cohort & Case-Control Studies. Identify the variables, describe the method, and explain how you would analyse the results.

Common Mistakes to Avoid

  • Ignoring units and significant figures in calculations.

  • Cramming content while neglecting experimental-design and data-analysis questions.

  • Describing what happens instead of explaining why — extended questions grade the mechanism, not the observation.
