What this practice covers
These questions are drawn from past AQA A-Level papers and filtered to the price mechanism and market equilibrium. 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 the price mechanism and market equilibrium, taken from our own topic notes. Read them before you practise and you will recognise the traps in the questions.
- Naming the three functions without explaining how each operates in the given market.
- Saying prices "cause" demand to change, a price change causes a movement along the demand curve, not a shift.
- Confusing excess demand with an increase in demand.
- Claiming the price mechanism always allocates efficiently, ignoring market failure.
- Forgetting that rationing by price is about ability as well as willingness to pay, an equity point.
- Describing the adjustment as instantaneous, ignoring elasticity of supply and time lags.
