Edexcel IGCSE History: Paper 2 Investigation and Breadth Studies — Revision Notes

Condensed for the final weeks. For the full explanation, use the Paper 2 Investigation and Breadth Studies study guide.

Confirm your options before revising anything else

Paper 2 offers 13 total choices across two independent selections: 5 Historical Investigations and 8 Breadth Studies. Shared revision notes found online, or even a well-meaning classmate’s notes, may cover the wrong pairing entirely. Confirm your centre’s chosen Investigation and Breadth Study first — everything below assumes that is already settled.

The Historical Investigation tests a skill, not a fixed narrative

Because this component includes unseen sources in the exam itself, over- memorising narrative detail (as if it were a second Depth Study) is a misdirection of revision time. The actual skill being tested is evaluating an unfamiliar source using contextual knowledge, not recalling a fixed sequence of events. Revise the background narrative as context that supports source evaluation, not as content to recall for its own sake.

Weak vs strong on source usefulness:

Weak	Strong
Describes what the source says, then asserts it is useful “because it gives detail”	Evaluates origin, purpose and content against the specific enquiry named in the question, using contextual knowledge to judge reliability

The Breadth Study tests change over time, not a list of events

A Breadth Study spans a long period — sometimes a century or more. Revising it as a sequence of disconnected events, rather than explicitly addressing change, continuity and pace of change, misses what the assessment objectives for this component reward. Build a timeline before anything else, marking:

• Turning points — moments where change accelerated or reversed.
• Periods of continuity — stretches where little changed.

Exam questions frequently ask “how far” or “how much” something changed over a stated period — a timeline-based answer directly supports that question type; a narrative list of events does not.

Assessment objective weighting to plan revision around

AO1 (knowledge and understanding of key features and characteristics) carries 34% and AO2 (explaining and analysing using concepts like cause, consequence, change and significance) carries 36% across the whole qualification — together the clear majority of marks. Even on a source-based component like the Investigation, secure factual knowledge remains the foundation: strong source evaluation still depends on accurate contextual knowledge, not source-reading skill alone.

A shared method across both components

Step	Historical Investigation	Breadth Study
Build	Contextual background to interpret unseen sources	A timeline of turning points and continuity
Apply	Evaluate origin, purpose, content of a given source against the enquiry	Judge how far/how much change occurred over the stated period
Avoid	Memorising a fixed source-by-source narrative	Listing events without linking them to change

Practising the unseen-source question specifically

Because the Historical Investigation includes sources unseen before the exam, timed practice on genuinely unfamiliar sources related to (but not identical to) the studied topic is the single most useful preparation activity beyond building contextual knowledge. When practising, write out explicitly: what the source’s origin suggests about its likely perspective, what its purpose suggests it might exaggerate or omit, and what contextual knowledge helps judge whether its content is typical or exceptional for the period. Doing this as a fixed written routine, not just “in your head,” builds the habit that a rushed exam moment will otherwise skip.

Exam traps

• Revising the Investigation as if it were a Depth Study, over- memorising narrative and under-preparing source evaluation.
• Writing a Breadth Study answer as a sequence of events with no explicit judgement about change, continuity or pace.
• Using shared revision material without first confirming it matches your centre’s chosen Investigation and Breadth Study.
• Describing a source’s content without evaluating its origin and purpose against the specific enquiry asked.
• Under-weighting factual recall because the Investigation is source- based, despite AO1 and AO2 together carrying the majority of marks.

Depth Studies vs Paper 2 — two different historical skills

Paper 1’s Depth Studies (see the companion revision notes for that paper) reward narrow, detailed period knowledge and source evaluation within a defined depth. Paper 2 deliberately asks for two different skills instead: enquiry-based source evaluation across less familiar material (the Investigation), and long-range analysis of change (the Breadth Study). Treating Paper 2 revision as “more of the same” as Paper 1, rather than recognising it tests genuinely different historical skills, is a common source of misdirected revision time in the final weeks before the exam.

Self-test

1. Why must you confirm your centre’s chosen options before revising Paper 2 content?
2. What is the actual skill the Historical Investigation tests, beyond narrative recall?
3. What should a Breadth Study timeline mark, beyond a simple list of dates?
4. What do “how far” or “how much” questions specifically require, and which preparation method supports them?
5. What proportion of the whole qualification’s marks do AO1 and AO2 together represent, and why does that matter even for a source-based component?

Answers: 1. Paper 2 offers 13 total choices across two independent selections, so shared or generic revision material may cover a different Investigation or Breadth Study than the one actually taught. 2. Evaluating unfamiliar sources using contextual knowledge — origin, purpose and content assessed against a specific enquiry — not recalling a fixed narrative. 3. Turning points where change accelerated or reversed, and periods of continuity where little changed. 4. A judgement about the extent or pace of change over a stated period; a timeline-based revision approach, rather than a narrative event list, directly supports answering this question type. 5. 34% (AO1) plus 36% (AO2), 70% combined; it matters because strong source evaluation on the Investigation still depends on accurate contextual knowledge, not source-reading skill in isolation.
