Aditya Tiwari Sir

Founder, De Facto IAS · Law Optional & GS-2 faculty

Since 2018, Aditya Tiwari Sir has sent his Law Optional batches a weekly email titled "Current Developments in Law" — a hand-picked filter of which PIB releases, judgments, and policy notes actually carry exam value, and what trap students should watch for.

pibtracker is that filter, opened to every aspirant — not just his Law Optional batches.

Yearly pre-Prelims booklet

March each year. ~76 pages, ~1,180 release boxes. Same curation that caught 72% of 2026 Prelims source releases.

We built our own filter, then tested it honestly against every Current Affairs question on the last six UPSC Prelims papers. 86 of 159 CA questions across 2021–2026 had verifiable PIB source releases. For each one, we asked: did our scoring engine rank that exact source release in the top 10 of its publishing week?

Past Prelims paper	N	Top-10 hit rate	Top-20
2021	10	80%	80%
2022	12	67%	75%
2023	13	46%	62%
2024	12	58%	75%
2025	21	29%	52%
2026 (latest)	18	72%	89%
All 6 years — verified	86	56%	71%

Every PIB release we ranked is searchable. Every past exam question is linked to its source. You can verify any number on this page yourself — for example, the 2026 question on the Matsya-6000 submersible (PRID 2104039) or the Sudarshan Chakra mission (PRID 2156749).
