With the commencement of the new academic year 2023-24, the CBSE board has released the updated syllabus for all subjects, including Chemistry. In light of the recent pandemic, both students and educational boards have been striving for stability. The field of academics has undergone significant realizations and subsequent changes. The focus has shifted towards conceptual learning, departing from the conventional method of burdening students with heavy school bags. This shift aligns with the guidelines outlined in the 2020 NEP (National Education Policy), which emphasized the importance of conceptual understanding rather than rote learning and learning-for-exams.
To facilitate students and teachers in adapting to these changes, it is crucial to have a comprehensive understanding of the complete syllabus for Class 11 Chemistry in the academic year 2023-24. You can access the CBSE Class 11 Chemistry syllabus for 2023-24 to stay informed about the modifications. In this article, we will highlight the key changes made in the CBSE Class 11 Chemistry syllabus for the upcoming academic year
