Where are you in your preparation?
Five routes into the same library. Pick the one that matches today, not the one that matches your plan for next year.
Targeting Prelims
Fact recall under time pressure. Read the subject hubs, then test yourself against 1,605 topic-tagged MCQs including past-year papers.
Building Mains
Marks come from structure and practice, not from more reading. Start with answer writing, then work through model answers paper by paper.
Choosing an optional
The optional decides roughly a quarter of your Mains total. Compare subjects honestly first, then go deep — PSIR and Law are covered paper by paper.

Paper-wise entry points
Browse by GS paper
Each paper hub carries the official syllabus, what every clause actually tests, and the note library beneath it. Counts overlap — one article can sit in more than one paper.

Prelims + Mains core
Browse core subjects
Twelve subject hubs. Each one rolls up topic notes, guides and the current affairs tagged to that subject, so a single page carries both the static base and what changed this month.

Latest study notes
Static syllabus notes — the material that stays true between cycles, as opposed to the dated briefs above. One per subject, so you can see the spread.
All study notes — the full archive, paginated.
Before you rely on it
How this library is put together
Free material is worth exactly what you can trust in it, so here is how these pages are built and where they come from.
Sources
Static notes work from standard references and primary documents — the Constitution, ministry reports, PIB releases, the Economic Survey and Budget, PRS summaries and NCERT texts. Current-affairs briefs cite the report they came from.
Syllabus mapping
Every note is tagged to the GS paper and subject it answers, which is what the paper and subject hubs are built from. Tags overlap on purpose: one topic often serves Prelims recall and a Mains dimension at once.
Who writes it
Notes are produced by the Anantam IAS content desk and the faculty who teach these papers — the same people who run the classes and evaluate answer scripts. Meet the faculty.
Corrections
Data moves — schemes get revised, judgments land, incumbents change. If you find something stale or wrong, tell us and we will fix the page rather than leave it. Report a correction.
Read everything here free. Come to one class before you pay anyone.
If the notes are useful but you are still unsure what to study first, sit in a live GS session taught by ex-Rau's IAS faculty and leave with a starting order. No sales call, no brochure.
