Exam Tips
Use the Full Hierarchy
When asked to "describe the levels of organisation," always give a specific example at each level — not just the name. For instance: cell (muscle cell) → tissue (cardiac muscle tissue) → organ (heart) → system (circulatory system) → organism (human). Generic answers lose marks.
Link Back to Unit 1
Specialised cells from Unit 1 (root hair cells, red blood cells, palisade cells) are the building blocks of tissues. Examiners reward students who make this explicit connection — mention specific cell adaptations when describing tissues.
Always Include Plants
Questions often ask for examples from plants AND animals. Have at least two plant examples ready: leaf (photosynthesis organ) and xylem tissue (water transport tissue). Answers limited to animals alone are penalised on higher-mark questions.
Explain Consequences, Not Just Descriptions
For 4–6 mark application questions, simply listing facts scores 2–3 marks. To reach 5–6 marks, explain the chain of consequences: how does damage at one level affect the next level, and why? Use the word "therefore" to force yourself to explain rather than just describe.
