No coaching-brochure noise. Just the architecture of the exam: what's screening, what's merit, what counts toward your final rank, and what doesn't.
Two MCQ papers. GS-I sets the cutoff; CSAT only needs to be cleared, never maximised.

UPSC says calendar dates are “liable to alteration, if the circumstances so warrant”. For CSE 2026 the calendar listed the notification for 14 January 2026, but it was actually issued on 4 February 2026, so confirm on upsc.gov.in before you plan around these dates.

Official syllabus text: “Candidates may be required to write essays on multiple topics. They will be expected to keep closely to the subject of the essay to arrange their ideas in orderly fashion, and to write concisely. Credit will be given for effective and exact expression.”
Both papers test your ability to read and understand serious discursive prose and to express ideas clearly and correctly. They are of Matriculation (Class 10) standard and their marks are not counted for ranking, but you need at least 25% in each: your Essay, GS and Optional papers are taken into account only if you clear both. Paper-A is not compulsory for candidates from Arunachal Pradesh, Manipur, Meghalaya, Mizoram, Nagaland and Sikkim, or for PwBD (hearing impairment) candidates exempted from a 2nd/3rd language by their Board/University.
Cut-offs move every year with paper difficulty, vacancies and how the batch performs — treat these as a range to expect, not a target to just clear.

No. Paper-A (Indian language) and Paper-B (English) are qualifying only, and their marks are not counted for ranking. You must score at least 25% in each, because your Essay, GS and Optional papers are taken into account only if you clear both.
No. CSAT (GS Paper-II) is qualifying with a minimum of 33%, and the Prelims cut-off is decided on GS Paper-I marks only. Prelims marks are not added to your final score either; the final rank is based on Mains (1750) plus the interview (275), out of 2025.
