Hello,
CBSE is a concept based education board. The exam paper is unpredictable. Important questions cannot be marked in CBSE board. Same is the case with numericals also.
But you can practice NCERT in-text and exercises given at end of chapter for Chemistry. From the past few years, the external board paper has been given almost 70% from these only.
- There will be good number of questions from Surface Chemistry
- Raoults law
- Absorption isotherm
- Molar mass determination
- Organic chemistry mechanisms
- Numericals on Chemical Thermodynamics, Mole Concept, Solid State & Atomic Structure
You can consider these as some important topics.

Hope this helps.
Thanks.
