The Critical Path (memorise this sequence)

1. IDENTIFY the issue
2. GATHER and INTERROGATE evidence
3. EXPLORE multiple perspectives
4. FORM a reasoned personal view

Content knowledge is not credited for its own sake — marks come from the quality of reasoning applied to the sources given on the day.

Deconstructing an argument (claim → reasons → evidence → assumptions → conclusion)

Flaw What it looks like
Hasty generalisation Broad claim from limited cases
False cause Correlation treated as causation
False dichotomy Two options presented as the only ones
Ad hominem Attacking the arguer, not the argument
Appeal to authority Citing status instead of evidence
Circular reasoning Conclusion assumed within the premises
Straw man Misrepresenting a view to defeat it easily

Naming a flaw is only half the mark — always explain why it undermines the argument’s inference.

Evaluating evidence

Judge on: provenance (who, why), methodology (sample, selection, replicability), currency, corroboration, sufficiency. For statistics: check the baseline, the sample size, and whether percentages are hiding small absolute numbers.

Perspectives

Perspectives come from contexts — economic, political, cultural, generational, geographic. Explaining why a perspective is held (its context) scores higher than describing what it says.

Worked example (condensed)

Claim: “Countries that invest more in education have higher GDP per capita, so increasing education spending will raise national income.” Weaknesses to spot: false cause (correlation does not establish direction), reverse causation (richer countries can afford more education, not just the other way round), confounding variables (governance, stability and infrastructure affect both), and sufficiency (no data given on timescale or size of the effect). Naming a flaw and explaining why it undermines the inference — not naming it alone — is what separates the top band.

Contested and interconnected issues

Global issues are characteristically contested and interconnected: a policy decision is rarely only economic, or only environmental — an energy policy, for example, is simultaneously economic, environmental, political and ethical at once, and a solution addressing one of these dimensions often creates a new problem in another. Recognising and naming this kind of trade-off explicitly, rather than analysing a single dimension in isolation, is a marker of a high-level response.

Building a sustained argument

A sustained argument holds one position consistently across the whole response, supports it with evidence that has actually been evaluated (not just cited), and addresses counter-arguments on their merits rather than raising and then dropping them. The conclusion should follow directly from the reasoning given, and explicitly acknowledging the limits of your own position is rewarded, not penalised — it is a sign of critical awareness rather than weakness.

Working with different source types

Because sources are unseen and drawn from varied global topics, build general skill in reading critically across different types of material — data-heavy reports, opinion pieces, and factual reporting — rather than researching specific topics in depth beforehand. Each type carries different evaluation priorities: a data-heavy source is best interrogated for sample size, baseline and whether a percentage is hiding a small absolute number; an opinion piece is best interrogated for the writer’s underlying assumptions and the strength of the reasons given for their view, rather than simply agreeing or disagreeing with the conclusion itself; and factual reporting is best interrogated for provenance — who produced it, why, and for what audience — since this shapes what has been included or left out. Comparing perspectives within a single source, or across two or more sources given together, is a recurring exam demand distinct from simple comprehension, so practise explicitly naming each perspective present and weighing it against the others rather than only summarising what each source says in turn.

Exam traps

  • Disagreeing with a conclusion instead of examining the reasoning that leads to it.
  • Naming a fallacy without showing how it operates in the specific source.
  • Describing a perspective without explaining the context it comes from.
  • Accepting statistics at face value without questioning sample, baseline or fair comparison.
  • Raising a counter-argument and then abandoning it instead of weighing it against your position.

Where this component sits in 9239

Component 1 is one of three AS-level components, alongside the Essay and the Team Project, and all three together form the AS Level on their own; the full A Level adds a fourth component, the Cambridge Research Report, completed either in the same series or in a second year of study. Because this component is externally set and marked, and based entirely on unseen source material, no amount of pre-learned subject content can substitute for practising the Critical Path itself under timed conditions — the skill being tested is the reasoning process applied on the day, not recalled knowledge of any particular global issue.

Self-test

  1. State the four stages of the Critical Path in order.
  2. What five things should you evaluate evidence on?
  3. Why does describing a perspective score lower than explaining its context?
  4. What’s wrong with “cases rose from 2 to 4, a 100% increase”?

Answers: 1. Identify the issue, gather and interrogate evidence, explore perspectives, form a reasoned personal view. 2. Provenance, methodology, currency, corroboration, sufficiency. 3. Because explaining why a perspective is held (its economic, political, cultural or other context) demonstrates deeper understanding than simply restating what the perspective claims. 4. The percentage is technically correct but the underlying sample (2 to 4 cases) is too small to be meaningful — a genuine example of a low-sufficiency statistic.
