Study Tips
- 1
Use precise scientific vocabulary; examiners award marks for correct terminology used in context.
- 2
Review required practicals and data-analysis skills — experimental questions appear on nearly every paper.
- 3
Make concept maps connecting topics — modern exam questions frequently cross unit boundaries.
- 4
Review class notes within 24 hours of each lesson — quick review dramatically improves retention.
- 5
Use homework as diagnostic practice: redo any problem you got wrong until it feels easy.
Past Exam Questions
Define Amino Acids & Proteins and state the key facts a student must know, using precise scientific terminology.
Explain the mechanism behind Enzyme Kinetics: describe what happens and, crucially, why it happens. Include a labelled diagram where appropriate.
Design an experiment (or interpret given data) to investigate Carbohydrates. Identify the variables, describe the method, and explain how you would analyse the results.
Common Mistakes to Avoid
- ✕
Describing what happens instead of explaining why — extended questions grade the mechanism, not the observation.
- ✕
Using vague everyday language where precise scientific terminology is required.
- ✕
Ignoring units and significant figures in calculations.
