What this practice covers
These questions are drawn from past Edexcel IGCSE papers and filtered to elasticity. 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 elasticity, taken from our own topic notes. Read them before you practise and you will recognise the traps in the questions.
- Comparing elasticity to zero instead of to 1.
- Saying "demand is elastic" without giving a value or a reason.
- Forgetting the minus sign on PED, or worrying about it too much. Say you are using the value ignoring the sign.
- Using absolute changes instead of percentage changes in the formula.
- Forgetting time, which is the strongest determinant of both PED and PES.
- Getting the revenue rule backwards. Inelastic → raise price to raise revenue.
Revise it first
