#WBS14 — 48-Hour Pre-Exam Checklist — Unit 4: Global Business

#What this document is (and isn't)

This is not a re-teach, and it isn't a fifth pass through the same content in a different order. The seven curriculum lessons carry the spec; FORGE carries tariff-by-tariff technique, a self-mark checklist and a short exam-day protocol; SIGNAL carries topic frequency and real grade boundaries; CODEX carries definitions and application material. This document assumes all four have already been used at least once, and answers a narrower question none of them answers directly: with roughly 48 hours left before sitting this specific paper, what should those hours actually contain?

Three windows, not a fixed timetable — adapt the hours to your own sitting time:

• T-48h to T-24h — the last full re-read pass, sequenced by what's actually confirmed to matter on this paper, not by gut feeling or by which lesson happens to be freshest.
• T-24h to T-2h — active self-testing only. No new reading. If something surfaces here that you can't do from memory, that's the signal to go back to the source lesson once, fix it, and re-test — not to keep reading around it.
• The final stretch — a short, explicit list of what not to start learning fresh this late, because the real evidence base for it is thin, or because it's a practised skill rather than a fact absorbed by reading it twice.

#1. T-48h to T-24h: the last re-read, in order

Sequence this by real, confirmed mark-weight and real, confirmed error rate — not by which topic feels least secure. FORGE's own arithmetic: Q1(d) and Q1(e) are 24 of Section A's 40 marks (60%), and the two 20-mark Evaluate essays add 40 more marks on top of that — together, Q1(d) + Q1(e) + Q2 + Q3 are 64 of the paper's 80 marks. That's where a re-read pass should spend most of its time.

1. The single highest-value trap on the whole paper, first. The October 2023 Principal Examiner's Report states directly that "a significant number of candidates" "knew little, or nothing, about Porter's matrix" and "confused it with Porter's five forces." Two different tools, two different spec points (4.3.3.1.d vs 4.3.2.2.b). Before anything else, confirm cold: which one is cost leadership/differentiation/focus, and which one is the five-force market-structure analysis (rivalry, new entrants, substitutes, supplier power, buyer power)? If that takes a pause to work out, this is the first thing to fix, not the last.

2. The two structural traps sitting inside Q1(d)/Q1(e). "Return on investment" as a location factor is a qualitative judgement about a business's decision, not the investment-appraisal calculation technique (QS6) — the October 2023 Examiner's Report notes candidates who did understand the term often "dismissed it without development." Exchange-rate exposure runs in opposite directions depending on whether the business in the question is entering a market or producing in it — the January 2024 report calls exchange rates "usually a tricky topic" for exactly this reason. Re-read both, specifically to check the habit isn't defaulting to a generic version of either.

3. The real band structures — know which one is being written to before starting. Three confirmed shapes on this paper, not one: the 8-mark Discuss is a 3-band descriptor (L1 1–2 / L2 3–5 / L3 6–8, confirmed identically in June 2022 and June 2026); the 12-mark Assess and the 20-mark Evaluate are both 4-band, but at different totals (Assess: L1 1–2 / L2 3–4 / L3 5–8 / L4 9–12, confirmed across three independent series; Evaluate: L1 1–4 / L2 5–8 / L3 9–14 / L4 15–20, confirmed across three independent series). Writing to the wrong shape — expecting a Discuss to need a full conclusion, or treating an Assess like it only needs "an attempt" — costs marks for a format reason, not a content one.

4. The recurring examiner checklist — read as a final habit, not a study topic. Independently repeated, close to verbatim, across the June 2022, October 2023 and January 2024 reports: read the question and answer what was actually set; watch the command word, especially Assess/Evaluate being ignored; use real examples; avoid generic or copied-out evidence; watch timing; write concisely; add a real conclusion to the longer answers. Three independent series repeating the same pattern is real evidence it's structural, not one cohort's issue — worth reading now so it's running in the background on the day, not encountered for the first time in the exam room.

5. Sequence the rest of the spec by SIGNAL's frequency table, not by feel. Use it to order the re-read, not to skip anything — a "0 of 5 in the systematic sample" row is not lower-priority; protectionism, market assessment and niche markets were all "0 of 5" in the original systematic pass, and all three turned out to be real, confirmed exam content once targeted pulls went looking for them.

Concrete re-read anchors, by spec area — the real named cases worth being able to summarise in one sentence each before T-24h:

Each of these already has full worked detail in its owning curriculum lesson — this table is a re-read index, not a substitute for the lesson itself.

#2. T-24h to T-2h: self-test, don't re-read

Everything below is a write-from-memory-then-check task. If it can't be done without notes, that's real signal about where the last hours should go — fix it once against the source, then re-test; don't circle back to re-reading instead.

• Command words, cold. Write the five real command words used on this paper with their real mark tariffs, without checking: Calculate/Construct (4), Explain (4), Discuss (8), Assess (12 — not 10), Evaluate (20). If "Assess = 10" comes out first, that's the Unit 1/2 tariff bleeding across papers — flag and fix now, before it costs marks on both Q1(d) and Q1(e).
• Band shapes, cold. Recite the three real band structures from §1.3 without looking. If Discuss comes out as four bands, or Assess comes out with a split L3, that's a placeholder convention some course materials still carry rather than the real, mark-scheme-confirmed shape — use the confirmed bands instead.
• BMW/Jaguar, both channels. Free-write the PED-inelastic export-side point and the separate input-cost-side retaliation point (the price and availability of imported raw materials and resources) as two distinct paragraphs. If they collapse into one "tariffs don't really affect BMW/Jaguar" sentence, that's the confirmed trap — inelastic export demand doesn't cover the import-cost channel.
• EU fishing subsidies, three separate costs. Free-write the balance against the $2bn/2018 EU subsidy figure: competitive inefficiency, retaliation, and the sustainability/fish-stock-depletion risk (the same extract's 12.5%-by-2050 figure). Three different kinds of cost, not one vague counterweight — check they stayed apart.
• One timed Q1(d)-or-(e) and one timed 20-mark essay, for real. 18 minutes and 30 minutes respectively, under real conditions, no notes open. Self-mark against FORGE's own §3 checklist afterwards. This is the single highest-value hour in this window — it tests timing, recall and technique together, which none of the individual items above can do alone.
• QS-code identification. Given a GDP-per-capita opener, a supply-and-demand Construct opener, and a price-elasticity opener, can the actual QS code each one is testing be named (QS2, QS3, QS7 respectively) before starting to answer? Getting the mode right — prose vs diagram vs calculation — is worth marks independent of whether the economics is correct.
• Grade-boundary calibration, not prediction. SIGNAL's own table shows the raw A boundary moving from 41 to 52 across the series it fetched — an 11-mark swing on an 80-mark paper. Use that fact once, to calibrate how much a handful of marks actually matters (worth fighting for a stuck opener, or worth abandoning it for Q1(e)?) — not as revision material to memorise, and not to guess this sitting's actual cutoff.

#3. What NOT to start learning fresh this late

Each item below is flagged thin or unconfirmed by this course's own research, or is a practised skill rather than a recall fact — reasons the last 48 hours are the wrong time to build it from zero.

• EU or NAFTA as the named case for a trading-bloc question. Neither was the central case in any series this course's research has read; ASEAN, plus the non-spec-named-but-real AfCFTA and RCEP, are the only confirmed applied cases so far. Building an EU or NAFTA example from scratch tonight, if one isn't already ready, is a poor use of the time left — go in with the ASEAN/AfCFTA/RCEP material already held, and treat the mechanism (competitive threat vs. market access, the customs-union/free-trade-area distinction) as the transferable part, not the specific named bloc.
• "Other trade barriers" and the general "reasons for protectionism" list. Tariffs, quotas, subsidies and the impact-on-businesses essay are all now confirmed, real, standalone content on this paper — but the broader non-tariff-non-quota "other barriers" catch-all and a generic "reasons for protectionism" list are not confirmed as standalone mark-scheme content in any pull this course's research has checked so far. That is a genuine gap in the evidence, not proof the topic won't appear — but it also means there is no real worked example to anchor last-minute learning to. Time is better spent consolidating the protectionism content that is confirmed (the Turkey tariff, the Indonesia quotas, the EU subsidies, BMW/Jaguar) than building new, unanchored content on the parts that aren't.
• Niche markets, if it isn't already secure. Real, but still the lower-confidence spec point on this paper — two confirmed series, each anchoring a different sub-point, against five or more for most of the rest of the spec. If niche markets is already learned, a quick self-test (the Halo Top 4Ps moves, the Green & Black's takeover risk) is worth the few minutes. If it isn't learned at all, this is not the spec point to build from zero at T-24h — the marks are better protected by shoring up a heavily-confirmed area instead.
• A second diagram type, if only one is drilled. Two genuinely different real diagram shapes exist for this paper: the ordinary one-curve-shift domestic-market diagram (confirmed by the real October 2024 Turkey-wheat Q1(a) Construct question) and a separate two-flat-lines world-supply-vs-world-supply-plus-tariff shape this course's own protectionism lesson teaches for the price-wedge-vs-quantity-cap contrast. If only one is confident, drill the one actually confirmed by a real past Construct question — don't split the last hours evenly across a second diagram type that hasn't been the one actually set.
• A calculation technique that hasn't already been practised. Investment appraisal (QS6) and index numbers (QS4) are both spec-confirmed quantitative skills on this paper, but learning a calculation method for the first time in the last 48 hours has a poor return. The technique actually worth reinforcing this late is procedural, not new: show the working. The June 2022 mark scheme's own NB rule drops a full mark for a correct GDP-per-capita figure missing its currency symbol, and the Examiners' Report is explicit that showing working is what protects a correct method when the arithmetic slips under pressure — a habit, not new content.
• Don't try to memorise a grade boundary as "the" boundary. See §2's calibration note — the number moves by double digits between series and isn't predictable from past series alone. Spending revision time on it has no real payoff.

#4. Scope

This document adds no new fact beyond what's already verified in the sources below — it is a sequencing and self-testing layer over material the curriculum lessons, FORGE, SIGNAL and CODEX already carry, built specifically around the 48 hours before sitting this paper. Where a re-read or self-test item above references a real figure, band, or quotation, it is restating something already independently verified elsewhere in this course, not introducing a new claim — check the owning document (named inline throughout) for the full worked mechanism and provenance.
