What this practice covers
These questions are drawn from past AQA A-Level papers and filtered to aggregate demand and the multiplier. 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 aggregate demand and the multiplier, taken from our own topic notes. Read them before you practise and you will recognise the traps in the questions.
- Forgetting that imports are subtracted in AD.
- Confusing a movement along AD (caused by the price level) with a shift (caused by anything else).
- Using 1 ÷ MPS as the multiplier in an economy with taxes and imports; it must be 1 ÷ MPW.
- Shifting AD by the size of the initial injection rather than the multiplied amount.
- Ignoring spare capacity, the multiplier's real effect depends on it entirely.
- Treating investment as a stable component; it is the most volatile.
