Designed for students studying Biology at upper secondary level. Topics and depth vary between courses and
countries. Use this guide alongside your teacher’s materials and current syllabus.
Understand the process. Connect the ideas. Explain the evidence.
, How to use this guide
Biology is the study of life: how organisms are built, how they function, how populations change, and how living things
interact with their environment. This guide uses plain English and examples to make major topics easier to learn.
• Preview: Read the headings and identify the key terms.
• Explain: Close the guide and explain the idea in your own words.
• Draw: Sketch a cell, a food web, a feedback loop or a DNA process.
• Practise: Answer the questions before checking the answer key.
• Review: For every wrong answer, write what made it wrong and how to improve it.
Exam tip: Knowing a definition is only the beginning. Biology questions often ask you to explain a mechanism, interpret
data, evaluate a method or support a conclusion with evidence.
What the command words mean
Command word What to do
Define Give the precise meaning of a term.
Describe State what happens or what the data show.
Explain Give reasons and link cause to effect.
Compare Identify similarities and differences.
Evaluate Weigh strengths, limitations and evidence before reaching a judgement.
Suggest Give a plausible answer supported by biological knowledge.
