What this practice covers
These questions are drawn from past Edexcel IGCSE papers and filtered to demand, supply and price. 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 price, taken from our own topic notes. Read them before you practise and you will recognise the traps in the questions.
- Confusing a movement along a curve with a shift of the curve. Only the good's own price causes a movement.
- Saying "demand falls" when price rises; that is a contraction, not a fall in demand.
- Shifting both curves when only one thing has changed.
- Confusing excess demand (a shortage at too low a price) with an increase in demand.
- Forgetting that demand needs willingness and ability to pay.
- Getting substitutes and complements the wrong way round.
Revise it first
