What this dot point is asking
OCR Unit 1 Section B is the period study essay: you choose one of two essay questions on your British period and write a sustained, analytical answer for AO1, worth 20 marks. The command words ("Assess", "To what extent", "How far do you agree") all demand the same thing: a ranked argument across the period that weighs factors against the question and reaches a substantiated judgement. This page teaches the technique; the option pages supply the content.
The answer
Read the command and find the claim
Plan a thematic, ranked structure
Organise the essay by theme or factor, not by chronology. For a causation question, each paragraph takes one cause; for a "how far" question, each paragraph takes one criterion (security, finance, foreign policy). Decide your ranking in advance, what was most important and why, so the essay builds towards a judgement rather than discovering it at the end.
Deploy precise evidence
Reach a substantiated judgement
The conclusion must answer the exact question with a judgement that follows from the argument: which factor was most important, or how far the claim holds. Do not hedge ("there were many factors") or save the judgement for a single final line. The strongest essays signal the judgement in the introduction and confirm it, with reasons, at the end.
Examples in context
A model introduction would name the factors, state which is most important, and signal the judgement in two or three sentences, so the marker sees an argument from the start rather than a warm-up paragraph of background.

Q1. To what extent was weak leadership the main reason for the instability of the years 1547 to 1553? [20 marks]
- What the marker wants. An AO1 essay ranking weak leadership (Somerset, Northumberland) against other factors (religious change, economic grievance, the rebellions of 1549), with precise evidence and a judgement on the main reason.
Q2. In a Section B essay, what should the conclusion do? [2 marks]
- Cue. Reach a substantiated judgement that answers the exact question, confirming the ranking built through the essay, rather than merely summarising.

OCR H505 Y106 202020 marksAssess the reasons why Henry VIII broke with Rome in the years 1527 to 1534.Show worked answer →
A Section B period study essay (AO1) on causation, marked by levels of response. The top level ranks the causes and judges; it does not narrate.
Structure. Open with a clear line of argument (the divorce was the trigger but Cromwell's statutory strategy gave the break its permanent form). Each paragraph takes one cause, supports it with precise evidence (the King's Great Matter from 1527, the Act of Supremacy in 1534), and weighs its importance.
Judgement. Conclude by ranking the causes and answering "why", distinguishing the trigger (the divorce) from the underlying drivers (ambition, anti-clericalism, Cromwell). The top level sustains analysis across the whole question.
OCR H505 Y106 201820 marksHow far do you agree that Henry VII was a successful king in the years 1485 to 1509?Show worked answer →
A Section B essay (AO1) inviting a "how far" judgement, weighing success against limits.
Structure. State a thesis (Henry was largely successful in securing the dynasty and Crown finance, though his methods stored up resentment). Group the evidence by theme (security, finance, foreign policy), each weighed for and against.
Judgement. Reach a clear, supported conclusion that answers "how far", not a list of achievements. The top level ranks the criteria of success and judges against them, with precise evidence throughout.
