What this practice covers
These questions are drawn from past IB Economics papers and filtered to how economists approach the world. 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 how economists approach the world, taken from our own topic notes. Read them before you practise and you will recognise the traps in the questions.
- Thinking a positive statement must be true. It must be testable.
- Classifying a statement by its topic rather than its wording, look for "should", "ought", "fair".
- Criticising a model for being unrealistic without asking whether it is useful.
- Treating ceteris paribus as a claim that other things really are constant, rather than an analytical device.
- Interpreting "rational" as "selfish" or "always correct".
- Comparing totals when a question requires marginal analysis.
