Study Tips
- 1
Make concept maps connecting topics — modern exam questions frequently cross unit boundaries.
- 2
Draw and label diagrams for every major process — reproducing them from memory is a powerful test of understanding.
- 3
Focus on explaining why things happen, not just what happens — exam questions reward cause-and-effect reasoning.
- 4
Practice with past papers from your specific exam board (AQA, Edexcel, OCR) — question styles differ meaningfully.
- 5
Learn the command words (describe, explain, evaluate) — each demands a different type of answer.
Past Exam Questions
Define Earth, Moon & Sun and state the key facts a student must know, using precise scientific terminology.
Explain the mechanism behind Planetary Systems: describe what happens and, crucially, why it happens. Include a labelled diagram where appropriate.
Design an experiment (or interpret given data) to investigate Stars & Stellar Evolution. 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.
