Topic frequency

How often each topic actually gets tested

Not an official Pearson weighting — Pearson doesn’t publish one for this paper. This is what this course’s own research found by reading real mark schemes and examiner reports series by series, counted honestly rather than assumed. Use it to prioritise review time, not to assume a topic near the bottom won’t appear.

Richest by series count

Business growth / mergers & takeovers / demergers
3.3.1.2
Anchored a Section B/C question in roughly 9 of the 15 series reviewed for this course's own research.

Also very heavily tested

Oligopoly
3.3.3.5
Anchored essay or extended-response content in at least 7 of the 15 series reviewed.
Minimum/maximum wage and labour-market intervention
3.3.4.3 / 3.3.5.2
Six-plus genuinely distinct real contexts (Malaysia, South Africa, Greece, Bangladesh, Mexico, Egypt) across the series reviewed.

Solidly, repeatedly tested

Monopoly and price discrimination
3.3.3.6
Repeatedly tested across the archive reviewed for this course.
Perfect vs. monopolistic competition
3.3.3.3–4
One exceptionally rich comparative essay in the archive, plus consistent MCQ reinforcement across series.
Concentration ratio
3.3.3.2
A recurring quantitative-skills item in Section A and Section B(a) across a large majority of series reviewed.

Thinner, but examinable

Monopsony
3.3.3.7
Two clean, fully-worked real contexts in the archive (British Sugar, Tata Steel) — but not one in every series. Don't skip it; don't expect a past-paper worked example to lean on every sitting.
Labour immobility
3.3.4.4
One complete worked example in the archive reviewed (Belgium).
Types of business
3.3.1.1
MCQ-only in the archive reviewed — no Section B/C essay precedent found across the 15 series checked.
Natural monopoly
3.3.3.6(e)
Exactly two brief evaluative-aside mentions across the 15 series reviewed, no standalone question found. Teach the definition cleanly — don't expect a past-paper scenario to cite.
