What this practice covers
These questions are drawn from past AQA A-Level papers and filtered to demand, supply and elasticities. You answer, you find out immediately whether you were right, and you get the reasoning for the correct option and for each distractor. Wrong answers go to a mistakes locker so you can come back to exactly those.
Practice is free. You need an account only so your progress and your mistakes are still there next time.

What examiners see students get wrong here
These are the errors that cost marks on demand, supply and elasticities, taken from our own topic notes. Read them before you practise and you will recognise the traps in the questions.
- Confusing a movement along the curve with a shift. Only the good's own price causes a movement.
- Dropping the sign in elasticity answers, the sign carries the meaning in YED and XED.
- Saying an elasticity is "high" without saying elastic or inelastic relative to 1.
- Treating "inferior good" as low quality; it means demand falls as income rises.
- Adding percentage changes to find the revenue effect instead of multiplying the factors.
- Treating a whole demand curve as having one elasticity.
- Judging PES from the steepness of a straight-line supply curve rather than which axis it cuts.
- Assuming whoever pays the tax to the government bears it.
