What are common errors in E2E stub topic exams? (2)

Incorrectly labeling the y-axis as 'price' and x-axis as 'demand' instead of 'quantity'

E2E stub topic

OCR

A-Level

This subtopic focuses on market equilibrium, where the forces of demand and supply interact to determine price and quantity in a competitive market. It explores how changes in market conditions lead to new equilibrium points and the efficiency of resource allocation via the price mechanism. Students apply these concepts to analyse real-world markets and evaluate government interventions.

Common Mistakes

Pitfalls to avoid in your exam answers

Confusing a shift in demand/supply with a movement along the curve when price changes
Incorrectly labeling the y-axis as 'price' and x-axis as 'demand' instead of 'quantity'
