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

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.
