How to practise biology.

  1. 1

    Learn diagrams by drawing them

    Sketch the cell, the heart or the nephron from memory, then check. Drawing fixes the labels better than reading.

  2. 2

    Link structure to function

    For every part, ask what it looks like and why that suits its job. It turns lists into reasons.

  3. 3

    Say it in one sentence

    After each chapter, write one sentence for each process. If you cannot, that is the part to revise.

  • 4

    Watch the exact words

    Many wrong options differ from the right one by a single word, such as 'always', 'only' or 'all'.

  • 5

    Redo your mistakes after a week

    Repeat the questions you got wrong after a few days. That is when a fact either sticks or fades.
