Drawing diagrams without labelling the new curve, new equilibrium price and new equilibrium quantity
“However, some candidates did not label either the shift in demand or the new equilibrium price/quantity and so did not achieve full marks.”— 4EC1 Paper 1, June 2023
How to fix: Every diagram is worth 3 marks: 1 for the correctly drawn shifted curve with a NEW label (e.g. D1, S1, SL1), 1 for the new equilibrium price (Pe1) marked on the y-axis, and 1 for the new equilibrium quantity (Qe1) marked on the x-axis. Arrows are NOT acceptable as labels — you must write the new curve name next to it. Use a ruler. Always check axes are labelled before moving on.
