Downloaded https://iapt.org.in/wp-content/uploads/images/syllabus-for-nse-ino-2022-2023.pdf on 2026-10-06 (22 pages; the PDF's own title field reads 'Syllabus-for-NSE-INO-2022-2023.docx', the first page reads 'Syllabus for National Standard Examination and Indian National Olympiad in Physics, Chemistry, Biology, Astronomy and Junior Science'); it is the file the IAPT home page links as 'Syllabus for NSE-2026-27'. Read with pdftotext (text layer clean). The 'Junior Science:' section is on pages 19-22, after Biology (pp. 2-5), Chemistry (pp. 6-11), Physics (pp. 12-16) and Astronomy (pp. 17-18). The 37 chapters of this file are cut from those pages. Compared programmatically: the Junior Science section of the PDF and the 'Junior Science' tab of the HBCSE syllabus page (https://olympiads.hbcse.tifr.res.in/how-to-prepare/syllabus/) were reduced to lower-case letters and digits and set side by side: apart from the printed page numbers (19-22) and the page's markup they are identical, and every unit title, every chapter title and every topic text of this file occurs in both (for the one topic that runs across the page break 21/22 it occurs in the PDF once the page number 21 is skipped). Item order and wording are the document's own. Not compared: the rendered page images; the PDF's file name carries 2022-2023 while IAPT labels it NSE-2026-27, so the session shown is IAPT's label.
