What this dot point is asking
OCR Unit 3 Section B is the thematic essay: you answer two essays from a choice of three, each worth 25 marks and testing AO1. The defining feature is that they are synoptic, you must argue across the whole period of the option (and, in Civil Rights, often across all the groups), tracing change and continuity and ranking factors. This page teaches the technique; the option pages supply the content. (Marks are shown capped at 20 in line with the site's display limit.)
The answer
The synoptic demand
Plan a thematic, ranked structure
Organise the essay by theme or factor, not chronology. For "how far were economic factors the main obstacle", each paragraph takes one type of obstacle (economic, legal, political, social) and weighs it across the whole period and across groups. Decide your ranking in advance so the essay builds towards a judgement.
Trace change and continuity
Manage the time and reach a judgement
You must write two 25-mark essays plus the interpretations essay within 2 hours 30 minutes, so budget your time and do not let one essay sprawl. Each essay must end with a substantiated judgement that answers the exact question, ranking the factors across the period, not a one-line summary.
Examples in context
A model essay draws at least one example from outside the obvious period or group in every section, so the marker sees genuine synoptic range rather than a narrow focus dressed up as a survey.

Q1. How far do you agree that the role of key individuals was the main driver of change for all groups in the USA in the years 1865 to 1992? [shown at the 20-mark cap; thematic essays are worth 25 in the full paper]
- What the marker wants. An AO1 synoptic essay weighing key individuals (King, leaders of NOW, AIM and labour) against other drivers (federal government, the Supreme Court, economic change) across all groups and the whole period, with a judgement.
Q2. What makes the Unit 3 thematic essay different from the Unit 1 period essay? [2 marks]
- Cue. It is synoptic across the whole period (and often across groups), tracing change and continuity over the full span, rather than focusing on a single shorter period.
