What this practice covers
Real past-paper questions, the answer key from the mark scheme, and the explanation that goes with it. Each one is marked the moment you pick, the correct option is shown whether or not you found it, and the full explanation opens either way. No account needed to answer them.
These questions are drawn from past Edexcel A-Level papers. 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 national income, taken from our own topic notes. Read them before you practise and you will recognise the traps in the questions.
- Listing saving as an injection; it is a withdrawal. Only investment is the injection.
- Assuming equilibrium means full employment. It does not.
- Confusing wealth (a stock) with income (a flow), the single most common error in this topic.
- Forgetting that withdrawals adjust automatically as income changes, which is what produces the new equilibrium.
- Treating the circular flow as a closed model when the question involves trade or government.
- Ignoring the multiplier when tracing the adjustment.
