Biology: Diagrams, Labelling and Long Answers

Biology is a subject where good presentation earns marks. A neat, labelled diagram and a well-organised answer often score better than a long one with no structure.

Diagrams

• Practise the important diagrams of every chapter until you can draw them in two or three minutes.
• Use a sharp pencil and a ruler for label lines. Never let the lines cross.
• Label clearly in capital letters or neat handwriting, and give the diagram a title.
• Draw large enough that every part can be seen.

Learn the terms exactly

Biology uses precise words. "Osmosis", "diffusion" and "active transport" are not the same, and examiners expect the correct term. Keep a glossary at the end of your notebook with every new term and its definition, and read it often.

Long answers

1. Begin with a definition or a one-line introduction.
2. Use short points or numbered steps, not one big paragraph.
3. Include a diagram when one helps.
4. End with an example or a conclusion.

Making it stick

• Draw flow charts for processes such as digestion, circulation and photosynthesis.
• Teach a chapter aloud to a family member or a friend. If you cannot explain it, go back to it.
• Revise with questions, not only reading. Turn each heading into a question and answer it from memory.

Last-week tip

Make one page for each chapter with the diagram, five key terms and three important points. These pages are your final revision.
