What this practice covers
These questions are drawn from past AQA A-Level papers and filtered to aggregate supply. 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 supply, taken from our own topic notes. Read them before you practise and you will recognise the traps in the questions.
- Drawing LRAS as upward-sloping; it is vertical (classical) or three-sectioned (Keynesian).
- Shifting LRAS for a change in production costs. Costs shift SRAS; only capacity shifts LRAS.
- Presenting the Keynesian LRAS with only the horizontal section, omitting the upward-sloping and vertical parts.
- Saying the classical model means demand policy never works, it works in the short run.
- Ignoring where on the AS curve the economy currently sits, which determines the entire outcome.
- Confusing a movement along AS (price level change) with a shift.
