Common failure modes
These are the patterns that cause most candidates to lose marks on this topic. Recognising them in advance is half the work.
- !Confusing elastic vs inelastic demand questions — misidentifying the decision boundary (PED = 1)

- !Mixing up GDP and GNP definitions in national income questions
