All transcribed topper notes, model answer copies and books, arranged by the UPSC Mains syllabus — sources labelled, and datable facts verified against reputable sources. Choose a paper to begin.

Scope & honesty: a faithful transcription of one aspirant's note-set (plus two model answer copies and one book) — not the entire syllabus. GS-II here is only Social Justice & International Relations (no Polity / Constitution / Governance). World geography and a structured economy spine are thin. Datable facts carry a verified ⟳ update; timeless content (history, theory, quotes) is not "updated" because it does not change. Original note text is preserved verbatim; [illegible] marks unreadable handwriting.
