#HOW TO READ THIS MATRIX

Ratings based on: raw frequency across 21 confirmed series (Jan 2019–Oct 2025) + recency + gap length + rotation logic.

🔴 HIGH (>60%): long gap, historically frequent 🟡 MEDIUM (30–60%): moderate gap, regular rotation 🟢 LOW (<30%): recent appearance or low historical frequency ⚪ VERY LOW (<15%): appeared in last 1–2 series

---

#SECTION D — ESSAY PROBABILITY (Q13/Q14)

---

#CURRENT PRIORITY RANKING

TIER 1 — PREPARE IN FULL (all 5 judgement elements + 2 chains):
  🔴 Exchange rates / current account  — 3-year gap
  🔴 Fiscal policy                     — 2-year gap, high frequency

TIER 2 — PREPARE JUDGEMENT + ONE CHAIN:
  🟡 Recession costs
  🟡 Inflation costs
  🟡 Demand-side vs supply-side comparison

TIER 3 — KNOW THE CONTENT:
  🟢 Supply-side (possible as Q14 counterpart)
  🟢 Unemployment

SKIP (appeared last 1–2 series):
  ⚪ Monetary policy (Jan 2026)
  ⚪ Objective conflicts (Oct 2025)
  ⚪ Growth and living standards (Jun 2025)

#Q12e TOPIC PROBABILITY

#Q12a DEFINE TERM FREQUENCY

Likely candidates not recently tested: Deflation, balanced budget, structural unemployment, productivity, GDP per capita.

#SECTION B — QUESTION TYPE FREQUENCY

#OWN-COUNTRY RECOMMENDATIONS

UK — deepest data bank, most series-relevant. Primary choice for most topics. India — appeared 4× as extract country. Strong data: unemployment 7.1%→8.5%, CPI 7.01%, base rate 4.4%→4.9%. South Korea — zero extract appearances (good — not overexposed). Excellent data: rate 1.25%→3.5%, productivity 30% below USA, GDP per capita $150→$30,000. China — 4× extract. Strong data: PBoC 3.7%→3.65%, GDP forecast 5.5%→4.3%, infrastructure ¥1.48tn.

#THE ROTATION RULES

Rule 1: No exact repeat in back-to-back series. Gap minimum 2–3 series. Rule 2: Q13 and Q14 are always distinct topic families. Rule 3: Extract context and Section D often share thematic link. Rule 4: Intervention vs market debate alternates — after several topic-specific series, a comparison question grows more likely.

#PROBABILITY REASONING — WHY EACH RATING

The one-sentence reasoning per topic explained in full. Use this to understand the logic, not just the rating.

Exchange rates / current account — 🔴 HIGH Last Section D appearance was Jan 2021 — over 4 years ago. In those 4 years, supply-side (×2), monetary policy (×2), fiscal (×1), inflation (×2), objective conflicts (×2), unemployment (×3), growth (×2) have all appeared. Exchange rates is now the single longest-absent major topic. The rotation logic means it is structurally overdue. Combined with a global context of currency volatility (Egypt, Argentina, Turkey all featuring as recent extract countries), the examiner pool has fresh data to draw on.

Fiscal policy — 🔴 HIGH Last appeared Jun 2023 — a clean 2-year gap. Fiscal policy averaged approximately once every 4 series historically. It is now at 5 series without an appearance. Post-Covid fiscal consolidation debates (UK austerity reversal, IMF fiscal rules) provide natural extract contexts. The absence of an expansionary fiscal 20-marker since 2023 makes it statistically overdue.

Recession costs — 🟡 MEDIUM Last appeared Jun 2023 (Germany/Ireland context). Gap is 2 years. Germany's technical recession provides fresh data. However, objective conflicts and unemployment have appeared since, partially covering related content. Rated medium rather than high because the topic has appeared in Q12e format more recently, and Pearson avoids exact repetition even in different question formats.

Inflation costs — 🟡 MEDIUM Last appeared Oct 2023 (Egypt context). 18-month gap. Egypt's 27.25% base rate and 35% currency depreciation remain highly relevant extract material. However, the Jan 2024 Turkey inflation causes appearance partially covered related territory. Medium probability — present but not the highest priority.

Demand-side vs supply-side comparison — 🟡 MEDIUM Has appeared only twice (Jan 2024 as Q14 framing, once earlier). The comparison format has grown in frequency in recent years as the IAL curriculum has emphasised policy trade-offs. Moderate frequency but growing trend.

Supply-side — 🟢 LOW (not skip) Despite being the highest-frequency topic overall (7/21), Jun 2025 appearance as Q13 makes a repeat in the next series unlikely given the rotation rule. However, supply-side could appear as Q14 while Q13 covers a different topic — so it is not safe to deprioritise entirely. Know the content; reduce drill priority.

Monetary policy — ⚪ VERY LOW Appeared Jan 2026. The rotation rule makes an exact repeat in the next series (~95%+ unlikely). Deprioritise for Section D, but the content remains essential for Section C Q12e where monetary policy is the most frequently tested extract topic.

Objective conflicts — ⚪ VERY LOW Appeared Oct 2025. Two-series gap minimum before rotation. Skip for Section D preparation.

Growth and living standards — ⚪ VERY LOW Appeared Jun 2025 (GDP limitations context). Too recent. Skip.

#HOW TO USE THIS MATRIX UNDER TIME PRESSURE

If you have limited study time before the exam, this matrix tells you exactly where to concentrate:

Tier 1 (full preparation — all 5 judgement elements + 2 full chains): Exchange rates, Fiscal policy

Tier 2 (judgement template + both chains, lighter drill): Recession costs, Inflation costs, Demand-side vs supply-side

Tier 3 (know the content, no essay drill needed): Supply-side (possible as Q14 counterpart), Unemployment

Do not drill for Section D: Monetary policy, Objective conflicts, Growth and living standards
