 CBSE Class 12 Chemistry Syllabus - Free PDF Download

Chemistry is a very important subject which teaches useful skills. Studying chemistry is a must for taking any career in medicine or engineering. So Chemistry needs to be given extra attention for a bright future. The CBSE Board has released the revised Syllabus of Class 12 Chemistry for the academic session 2022-23. As stated by the Central Board of Secondary Education, the new syllabus will be similar to the CBSE Class 12 Chemistry 2019-2020 Syllabus. There are no chapters that have been newly added or exempted from the existing syllabus. As per the revised Class 12 Chemistry Syllabus, the theoretical part will include 70 marks and the evaluation scheme will be 30 marks.

This page gives detailed information on CBSE Class 12 Chemistry Syllabus 2022-23 which can be referred for Class 12 CBSE Board Examination.
