A few useful answers
What is included in this Class 9 library?

Are Mathematics and language notes available here?
This page currently covers the Science and Social Science collections shown above. It does not include a dedicated Class 9 Mathematics or language collection.
How should I use an older chapter when my textbook has changed?
Look for a shared concept rather than relying on the chapter number or title. Read the relevant explanation, then return to your prescribed textbook for its examples, exercises and expected depth. Ask your teacher if you are unsure whether a topic is included.
