All Class 9 chapters for 2026-27: Maths, Science and the other subjects
Chapter counts for every CBSE Class 9 subject in the 2026-27 session, the full Maths and Science chapter lists, and a simple way to plan your study.
When the new session starts in Class 9, the first question is which chapters you will study this year. Here are the chapter counts for all six subjects and the full lists for Maths and Science. This is the same list DepLearn uses for Class 9, which follows the 2026-27 NCERT books.
Keep in mind
Chapter names are written exactly as they appear in DepLearn. Your school may use a different order or slightly different names, so always check your school's annual syllabus and your teacher's list too.

How each chapter is split in DepLearn
Every chapter has six levels. Levels 1 to 5 have five questions each, and level 6 is a 10-question boss challenge. This takes you from easy questions to harder ones step by step.
How to plan your study from this list
- First, mark each chapter on the list: strong, okay or weak. Be honest, because this decides where your time goes.
- Take the weak chapters first, but do not drop the strong ones completely. Revising them once a week is enough.
- A little every day. Even one level of one chapter a day builds good practice over a week.
- Write wrong answers in a separate notebook and solve those same questions again the next week.
