About the project
About Ritik Sir Notes
A free, independent study library for CBSE Class 10 and Class 11 mathematics — built by a student who benefited from concept-first teaching and wanted to pass it on.
Why this site exists
Most maths notes online are either a scanned PDF with no explanation or a wall of formulas with no context. Both are hard to learn from, especially when you are already anxious about the subject. Ritik Sir Notes was started to fill that gap: chapter-wise explanations written in plain English, with the formulas, the traps and one concrete exam habit on the same page.
The site is inspired by the teaching style of Ritik Mishra (Babua Sir), the Physics Wallah mathematics educator known for explaining the “why” before the formula. It is a fan project. It is not his website, and he has not written or approved this material.
Who runs it
What the site covers
- Class 10 maths — all 14 chapters of the CBSE syllabus, with formulas, common mistakes and exam tips.
- Class 11 maths — all 14 chapters, from sets and trigonometry to limits, derivatives and probability.
- Formula sheets — one printable page per class for last-week revision.
- Study guidance — a 30-day board-exam plan, a revision routine and honest advice about what does and does not work.
Our independence
Ritik Sir Notes is not affiliated with, endorsed by or sponsored by Ritik Mishra, Physics Wallah, CBSE or NCERT. We do not sell courses, collect enrolment fees or act as an agent for any coaching platform. Batch details and book titles are reported from public sources, and we link to official platforms rather than pretending to be one.
All trademarks, book titles and brand names belong to their respective owners. Where we use a portrait of a public figure, it is for identification in an informational profile; rights remain with the owner and we will remove it on request.
How we keep the content honest
Formulas and chapter lists are checked against the NCERT textbook and the official CBSE curriculum for 2026-27 before a page is published. We do not guarantee marks, rank or results, and we do not publish invented testimonials, awards or statistics. If a source conflicts, we say so or leave the detail out. The full process is described in our editorial policy.
How the site is funded
Hosting is paid for by advertising through Google AdSense. Ads are clearly separated from the content and never placed inside a chapter table or formula. If you use an ad blocker, the notes still work — no content is locked behind an ad or a subscription.
We do not sell personal information. Cookie and advertising details are explained in the Cookie Policy and Privacy Policy.
Corrections and contact
Maths notes should be correct, and ours occasionally are not. If you find a wrong formula, a typo in a definition or a chapter that does not match the current syllabus, email ahmedlaskarbazid@gmail.com with the page link. Genuine corrections are made quickly and the page’s “last updated” date is changed. We do not argue about corrections; we fix them.
