How to Use Past Papers Effectively
1
Master topics before full papers
Attempt topic-wise questions first — stoichiometry, bonding and organic chemistry decide most grades. Then move to full papers.
2
Mark with the official scheme
IGCSE marking is precise — learn the exact keywords examiners reward, especially for 3-6 mark extended answers.
3
Drill the practical paper
Paper 6 (Cambridge) and practical-based questions need exam technique, not just theory. Practise describing experiments step by step.
4
Sit full papers under time
Once comfortable, do full papers under strict exam timing — the multiple-choice paper especially rewards speed and accuracy.
