What this practice covers
These questions are drawn from past Cambridge IGCSE papers and filtered to price elasticity of supply. 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 price elasticity of supply, taken from our own topic notes. Read them before you practise and you will recognise the traps in the questions.
- Giving PES a negative sign. It is normally positive.
- Confusing PES with PED, or applying the total revenue test to PES, that test belongs to PED.
- Saying "supply is inelastic" without saying over what time period.
- Mixing up spare capacity (ability to produce more) with stocks (goods already made).
- Calculating PES and then not explaining what it means.
