# Physics — NCERT Class 12 — CBSE (NCERT textbooks) — Shishya school context > Subject page: https://shishya.in/schooling/cbse/class-12/physics · class: https://shishya.in/schooling/cbse/class-12 (context: https://shishya.in/schooling/cbse/class-12/context.md) · data as of 2026-10-10 (IST). Free to cite; link back to the subject page. > Honesty: Shishya never reproduces, summarises or translates textbook text — read a chapter at its official link. Practice questions are Shishya's own, written by AI and answer-checked before they are shown; they are not NCERT exercises, not board questions and not previous-year questions. A chapter marked "not ready yet" has no Shishya notes or practice, and its Shishya page is not linked here. > Children: Class 1-7 school pages have no chat tutor, offer no sign-in and ask no child to create an account. On Class 8-12 pages a student may sign in to save practice to an account — for students 13 and above; no school page asks anyone their age or role — and anyone can read a chapter, take its practice where the chapter has one and ask the AI tutor about it without signing in; the tutor says it is an AI and answers study questions only, with a daily message limit. The 5-question practice on the chapter pages that have it needs no account, and no result is saved to any account or profile from it: Shishya records only an anonymous usage event (which chapter was practised and the score) — on Class 8-12 pages with the same cookie-based analytics every page view sends, on Class 1-7 pages with no cookie, account or other visitor identifier. A signed-in student's own practice set is saved to that account. ## Physics - Book: Physics Part-I — https://ncert.nic.in/textbook.php?leph1=0-8 (NCERT also lists Hindi, Urdu editions) - Book: Physics Part-II — https://ncert.nic.in/textbook.php?leph2=0-6 (NCERT also lists Hindi, Urdu editions) - Chapters (14;
