UPSC CDS Previous Year Question Papers – Download PYQs & Answer Keys

UPSC CDS 2026

Union Public Service CommissionGraduate medium

UPSC CDS PYQs are available for all three papers (English, GK, Mathematics) from both CDS I and CDS II going back to 2010 on the official UPSC website. Since CDS is biannual, candidates have access to two paper sets per year.

Why CDS PYQs Are Essential

  • GK questions reveal recurring theme patterns – Defence news, Physical Geography landmarks, and Constitutional provisions appear every cycle
  • English PYQs show UPSC's preferred question formats (error spotting, para jumbles, comprehension style)
  • Mathematics PYQs reveal the exact difficulty ceiling – never higher than Class 10 level
  • Benchmark your score against historical written cutoffs to gauge SSB shortlist probability

Frequently Asked Questions

Q.Are CDS GK questions repeated across cycles?

Direct repetition is rare but topic patterns repeat strongly. Physical Geography questions (mountains, rivers, climate), Constitutional provisions, and Defence-related current affairs appear in similar forms across multiple CDS cycles.

Q.How many CDS PYQ papers should I solve?

Solve at least 10 years of both CDS I and CDS II papers (20 paper sets total) across all three subjects. This gives ~2,400 questions covering the complete CDS question spectrum.

Q.Are answer keys for CDS PYQs always correct?

UPSC's official answer keys are generally accurate. Occasionally, disputed questions are dropped or revised after an objection window. Always use the final revised key available on upsc.gov.in for each cycle.

Q.Is there a difference between CDS I and CDS II PYQ difficulty?

The difficulty level is broadly similar between both cycles. CDS II GK may emphasize more recent events (covering the gap since CDS I), so current affairs coverage must be updated between cycles if preparing for both.
