What this practice covers
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 revenues, costs and profits, taken from our own topic notes. Read them before you practise and you will recognise the traps in the questions.
- Confusing diminishing returns (short run, one fixed factor) with diseconomies of scale (long run, all variable). This is the biggest discriminator in Theme 3.
- Giving the shutdown point as ATC rather than AVC in the short run.
- Saying normal profit means zero profit. It is zero economic profit and a cost.
- Drawing MC cutting ATC anywhere other than its minimum.
- Saying diminishing returns means total output falls; it is the marginal product that falls.
- Forgetting AR = price = the demand curve.
- Listing economies of scale without explaining how each lowers average cost.
Revise it first
