Ritik Sir (Babua Sir): Frequently Asked Questions

Ritik Mishra, known to students as Ritik Sir or Babua Sir, is an Indian mathematics educator who teaches CBSE Class 9 and Class 10 mathematics on Physics Wallah. He is recognised for explaining concepts before formulas, using real-life analogies and diagrams, and for publishing concise handwritten notes for board preparation.

He is a chemical engineering graduate of MANIT Bhopal (B.Tech), and he joined Physics Wallah as a mathematics faculty member in 2021. Some older websites list a B.Sc; we follow the more recent and better-sourced information. He also prepared for CA, CAT and UPSC before turning to teaching full time.

We do not publish an exact date of birth or age. Public profiles disagree, and personal details that are not confirmed by the person himself are not something this site wants to repeat. What matters for students is his teaching, not his birthday.

Yes. He runs a YouTube channel dedicated to CBSE Class 9 and 10 mathematics with one-shots, chapter marathons and revision series, and an Instagram account where he posts updates between batches. Unofficial fan accounts are common — verify through the Physics Wallah app before following a lookalike.

His Physics Wallah batches focus on CBSE Classes 9 and 10. The Class 11 notes on this site are independent material we publish for students moving into senior secondary mathematics. They are not transcripts of his classes and should not be presented as his work.

Over the years he has been associated with Udaan (Class 10), Neev (Class 9), Warrior (board-focused revision), Project 45 (short revision) and bridge courses for the Class 9 to 10 transition. Batch names and editions change every session — check the Physics Wallah app for the current list rather than relying on an old blog post.

Download the Physics Wallah app, open the batch or class section, and search for “Ritik Mishra” or the batch name. Enrolment links are published inside the app and on PW’s official channels. This site does not sell courses, take payments or act as an agent for PW.

No. The notes here are written independently for this site and checked against the NCERT textbook and the CBSE syllabus. Ritik Sir’s official notes are either printed books (such as CBSE Class 10 Mathematics Made Easy) or PDFs shared inside the PW app and his YouTube descriptions. We do not copy or redistribute those files.

Yes. Every chapter note, formula sheet and study plan can be read without an account. The site is supported by advertising. Use the print button on any notes page to save a clean PDF copy for offline study.

Open the chapter page, press Print / Save as PDF at the top, then choose “Save as PDF” in your browser’s print dialog. Menus, ads and the side navigation are removed automatically, so you get a clean A4 document. On Android, use “Share → Print” in Chrome.

Yes. The chapter lists and unit weightages follow the rationalised CBSE curriculum for 2026-27: 14 chapters in Class 10 and 14 chapters in Class 11. Topics such as Constructions (Class 10) and Mathematical Reasoning (Class 11) are no longer separate chapters, so they are not covered. Always confirm against the official syllabus at cbseacademic.nic.in.

By unit weightage: Algebra carries 20 marks, Geometry 15, Trigonometry 12, Statistics and Probability 11, Mensuration 10, Coordinate Geometry 6 and Number Systems 6. Within algebra, quadratic equations and arithmetic progressions are among the most predictable scorers. Read the chapter notes or the 30-day plan for a priority order.

Nobody can promise 100, but the route to the high 90s is boring and reliable: finish every NCERT exercise, solve at least five previous-year papers under a timer, keep an error log and revise it weekly, and write formulas before substituting numbers so method marks are secured. Our 30-day study plan turns that into a schedule.

Choose Standard if you are considering science, commerce with maths, or competitive exams after Class 12 — it keeps those doors open. Choose Basic if maths is not part of your intended path and you want a more accessible paper. The syllabus content is largely shared; the difference is the level of difficulty. You can change the choice within the window CBSE allows, so ask your school early.

If you already follow his lectures, printed handwritten notes can save hours of copying and are useful for revision. If you are on a tight budget, the free notes on this site plus the NCERT textbook cover the same concepts — the printed books add compact revision and practice questions. Neither replaces solving problems yourself.

Around 60 to 90 minutes on a normal school day is enough if it is focused: 15 minutes of formula recall, 40 minutes of problems from one chapter, 10 minutes correcting mistakes. In the final month, add one full paper per week under exam conditions. Consistency beats long weekend sessions.
