What is the category-wise cutoff gap — General vs OBC vs SC vs ST vs PwBD?

TL;DR

The gap is widest at Prelims, compresses through Mains, and is narrowest at Final. In CSE 2022, the General-to-ST Prelims gap was ~19 marks; at Final it shrank to ~60 marks out of 2025 — proportionally just 3% of total. Reserved-category toppers who beat the General cutoff routinely claim unreserved seats.

Can I get my UPSC answer sheet re-evaluated? What is the official policy?

TL;DR

No re-evaluation on merit is allowed. UPSC only permits a photocopy request (within 30 days of final result) and correction of clerical errors (un-totalled pages, un-evaluated answers). There is no provision to challenge the marks given on content. The Supreme Court in UPSC v. Angesh Kumar (2018) upheld this position.

What are UPSC's tie-breaker rules when two candidates score equal marks?

TL;DR

UPSC's revised tie-breaker (notified 28 August 2019, formalised 26 February 2020) uses two filters: (1) higher marks in Compulsory Papers + Personality Test combined, then (2) older candidate ranked higher. The pre-2019 three-filter rule has been simplified to this two-step cascade.

Cutoff vs scaling vs moderation — what is UPSC's official position?

TL;DR

These three are distinct. Cutoff is the minimum qualifying mark per stage/category. Scaling is subject-wise mathematical adjustment — UPSC does NOT use it. Moderation is examiner-wise standardisation — UPSC DOES use it. Conflating them is the single biggest source of cutoff myths.
