key tips for success
Learn your chosen options cold
OCR A offers several combinations. Your school picks: International Relations (compulsory) + 1 non-British depth + 1 British thematic + 1 linked British depth + historic environment. Focus revision on your options.
Master international relations chronology
Paper 1 spans 1918-c.1975. Learn key turning points: Versailles, League of Nations collapse, WW2, Yalta, Cold War flashpoints (Berlin, Cuba, Vietnam), detente. Prepare a decade-by-decade timeline.
Practise source analysis (AO3)
AO3 (15%) tests contemporary sources. Learn to comment on: provenance, content, tone, purpose, reliability, usefulness.
Master change/continuity for the thematic study
Paper 2 tests change over centuries. Learn key turning points, individuals and factors driving change (or continuity) across the long chronology.
Study the historic environment site carefully
Paper 3 includes a study of the historic environment linked to your British depth study (Urban Environments or Castles). Learn the site's history, purpose, evidence and how it reflects the wider period.
