What this practice covers
These questions are drawn from past CIE 9708 papers and filtered to demand and supply curves. 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 and supply curves, taken from our own topic notes. Read them before you practise and you will recognise the traps in the questions.
- Demand means desire. Demand must be effective: willingness and ability to pay.
- Demand and quantity demanded are identical. Demand is the whole curve. Quantity demanded is one amount at one price.
- A lower price shifts the demand curve right. A lower own price causes movement down the existing curve.
- Higher income always increases demand. Not for inferior goods.
- Higher price of a complement increases demand. It normally decreases demand for the related good.
- Higher price of a substitute decreases demand. It normally increases demand for the other substitute.
- Supply means stock. Stock is the amount physically available. Supply is the amount offered for sale at different prices during a period.
- Supply and quantity supplied are identical. Supply is the whole curve; quantity supplied is one amount at one price.
