Disclaimer
This is an independent, unofficial fan project. Here is exactly what that means — and what you should not expect from it.
1. No affiliation or endorsement
This website is an independent educational project created by a fan and student of mathematics. It is not owned, operated, endorsed, sponsored or approved by Ritik Mishra (Ritik Sir / Babua Sir), Physics Wallah (PW), CBSE or NCERT. Any statement suggesting otherwise is not authorised by us.
2. Trademarks and names
“Ritik Mishra”, “Ritik Sir”, “Babua Sir”, “Physics Wallah”, “PW”, “Udaan”, “Neev”, “Warrior”, “Project 45”, “CBSE” and “NCERT” are names or trademarks of their respective owners. They are used here only to describe, identify or comment on publicly available information. Their use does not imply any partnership or permission.
3. Content and accuracy
The notes, formula sheets and study plans are prepared with care and checked against the NCERT textbook and the CBSE curriculum for 2026-27. Even so, mathematics content can contain errors, and syllabuses, exam patterns, batch names and book editions change. The site is provided for general informational and educational purposes and should not be treated as the final authority. Always cross-check against the official CBSE curriculum and your own textbook.
We do not guarantee that any formula, chapter list or weightage shown here matches your school’s internal syllabus. If you find an error, please tell us so we can correct it.
4. No guarantee of results
Studying these notes does not guarantee a particular score, rank or admission. Exam outcomes depend on many factors, including your own practice, school teaching, exam-day conditions and the paper itself. Any anecdote or example on the site is illustrative, not a promise.
5. Not official notes or coaching
We are not a coaching institute and we do not sell courses. Ritik Sir’s official handwritten notes are published as books by Physics Wallah, and official class material is distributed inside the PW app and on his YouTube channel. This site does not host, sell or distribute those materials.
6. External links
The site links to external websites and services for convenience and reference. We do not control those sites, do not warrant their content, and are not responsible for their privacy practices, prices or availability. Following an external link is at your own risk.
7. Advertising
Advertising on the site is served by Google AdSense and is selected by Google’s systems, not by us. The appearance of an ad does not mean we endorse the advertised product, service or institution, and we do not verify advertisers’ claims. See the Cookie Policy for how advertising cookies work and how to opt out of personalised ads.
8. Images
The portrait of Ritik Mishra is used for identification in an informational profile of a public figure. Copyright remains with the original owner. If you are the rights holder and would like the image credited differently or removed, email ahmedlaskarbazid@gmail.com and we will act promptly.
