• Olympiads - Homi Bhabha Centre for Science Education Verified against the document
  Official website · Homi Bhabha Centre for Science Education (HBCSE), Tata Institute of Fundamental Research · 2026 · checked 5 Oct 2026
  Opened https://olympiads.hbcse.tifr.res.in/ on 2026-10-05; it is the Olympiads site of HBCSE (TIFR) and links the Syllabus, Olympiad Books, Information Brochures, Stages and Past papers pages and the 2026-2027 Mathematical and Science Olympiad pages.
• Syllabus - Olympiads (HBCSE) Verified against the document
  Syllabus · Homi Bhabha Centre for Science Education (HBCSE), Tata Institute of Fundamental Research · 2026 · checked 5 Oct 2026
  Opened https://olympiads.hbcse.tifr.res.in/how-to-prepare/syllabus/ on 2026-10-05 and read its text. The page carries the 'Syllabus for National Standard Examination and Indian National Olympiad in Physics, Chemistry, Biology, Astronomy and Junior Science' (tabs Biology, Chemistry, Physics, Astronomy, Junior Science) and a 'Mathematical Olympiad' tab. Every topic list in this file was cut from that page text and compared back with it (lower-case letters and digits only, ignoring spacing): every unit title and every topic phrase occurs in the page text. Not compared: the page as rendered (images); the lists of recommended books on the Mathematical tab are not syllabus and are not copied.
• Science Olympiad Brochure 2026-27 (English) Verified against the document
  Exam scheme / pattern · Homi Bhabha Centre for Science Education (HBCSE), Tata Institute of Fundamental Research · 2026 · checked 5 Oct 2026
  Downloaded the 32-page PDF linked from https://olympiads.hbcse.tifr.res.in/science-olympiad-2026-2027/ on 2026-10-05 and read its text layer. It describes Stage I (National Standard Examination), Stage II (Indian National Olympiads, p. 15), Stage III (Orientation-Cum-Selection Camps, p. 16), Stage IV (training at HBCSE, p. 20) and Stage V (international Olympiads, p. 20). The statements recorded in this file (stage names, what a camp does, the INO duration and the syllabus level) were each checked against those pages. Dates, venues, quotas and fees on those pages are not copied.
• Olympiad Books - Olympiads (HBCSE) Verified against the document
  Prescribed / recommended reading (published by the body) · Homi Bhabha Centre for Science Education (HBCSE), Tata Institute of Fundamental Research · 2026 · checked 5 Oct 2026
  Opened https://olympiads.hbcse.tifr.res.in/how-to-prepare/olympiad-books/ on 2026-10-05; it lists the books HBCSE sells or recommends for the Science and Mathematical Olympiads (INPhO, INChO, INBO, INAO problem books, experimental problem books, and the Mathematical Olympiad books). It is a book list, not a syllabus, and no chapter cites it.
