Cutoff Trends — What to Expect

The UPSC Prelims cutoff depends on three factors:

  • Difficulty level of the paper
  • Number of candidates who appeared
  • Number of vacancies advertised

In 2024, the cutoff jumped significantly due to a relatively easier paper. If the 2026 paper follows the recent trend of moderate-to-tough difficulty, expect cutoffs in the range shown above.
