Key Points to Remember for UPSC

  • UPSC frequently frames questions by mixing correct and incorrect pairings of movements with their leaders — always verify person-event-year combinations.
  • The Government of India Acts (1919 and 1935) are the most tested legislations in Prelims over the last decade.
  • Tribal and peasant movements are increasingly appearing in Prelims — know the region, leader, and cause for each.
  • Socio-religious reformers are often tested through statement-based questions comparing two or more reformers.
  • The chronology of Gandhi’s movements — Non-Cooperation, Civil Disobedience, Quit India — and the specific reason each ended is a perennial favourite.
  • Governor General–event mapping (e.g., Bentinck–Sati abolition, Dalhousie–Doctrine of Lapse) appears almost every year.
  • Books and authors (Naoroji, Tilak, Vivekananda) are tested as factual one-liners — memorise them.
