What this practice covers
These questions are drawn from past Cambridge IGCSE papers and filtered to opportunity cost. 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 opportunity cost, taken from our own topic notes. Read them before you practise and you will recognise the traps in the questions.
- Defining opportunity cost as "what you gave up" without saying next best.
- Listing every alternative rather than the single best one.
- Giving the answer in money when the question wants the forgone item.
- Confusing money cost with opportunity cost.
- Saying a choice has no opportunity cost simply because it was free of charge.
