UPSC Indian Statistical Service 2026: Statistics I and II Objective Papers
The UPSC ISS exam pattern below is checked stage by stage, so one stage cannot inherit another stage's scoring rules.
Statistics I and II (Objective)
Review pendingTakeMockTest covers the two objective Statistics papers of the Indian Statistical Service examination. Each paper is 80 questions for 200 marks in 120 minutes, with 2.5 marks for a correct answer and one third of that, 0.833 marks, deducted for a wrong one; multiple responses count as wrong and an unattempted question scores zero. Papers are English only. The pattern is marked review-pending because the exact paper scheme was read from official-document mirrors rather than directly from the UPSC notification itself, which could be reached only at its archive surface. The Indian Economic Service papers, General English, General Studies and the descriptive Statistics papers are outside this product.
