What this practice covers
These questions are drawn from past Cambridge IGCSE papers and filtered to firms. 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 firms, taken from our own topic notes. Read them before you practise and you will recognise the traps in the questions.
- Confusing horizontal with vertical integration.
- Getting backward and forward vertical the wrong way round.
- Saying growth is always beneficial, mention diseconomies of scale.
- Ignoring the reasons firms stay small, which is half the syllabus point.
- Using only employee numbers to measure size without noting its limits.
Revise it first
