What they ask

The prelims has two objective papers of 200 marks each. Only GS Paper I decides who reaches the mains, while CSAT has to be cleared at 33%. A wrong answer costs a third of that question's marks, so blind guessing hurts. The mains GS papers test whether you understand an issue and can take a view on competing social and economic goals, not how much you have memorised. Prelims marks are not added to your final score; the mains written papers (1750 marks) and the interview (275 marks) are.

How to prepare

  • Map every line of the GS Paper I syllabus to one source you will revise, then solve the official prelims papers on the UPSC website to see how deep the questions go.
  • Take a timed CSAT test every week. It is only qualifying, but falling below 33% ends your attempt however well you did in GS Paper I.
  • Pick your optional early. Its two papers carry 500 of the 1750 written marks, and the syllabus is set at honours-degree level.
  • Start writing timed answers months before the mains. Each paper is three hours, and the notice says marks are cut for handwriting that is hard to read.
  • Revise prelims topics with daily topic-wise practice quizzes on the free Improvam app, and note which areas cost you negative marks.
