What this practice covers
These questions are drawn from past Cambridge IGCSE papers and filtered to production possibility 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 production possibility curves, taken from our own topic notes. Read them before you practise and you will recognise the traps in the questions.
- Calling a point outside the curve "inefficient" instead of unattainable.
- Shifting the curve outward to show a recovery from unemployment. That is a movement towards the curve.
- Moving along the curve to show economic growth. Growth is a shift.
- Shifting the whole curve when only one good is affected.
- Forgetting to label the axes with the two goods.
- Saying a bowed-out curve shows constant opportunity cost.
