NCERT Class 11 Deleted Syllabus 2023-24: The National Council of Educational Research and Training is an autonomous organisation that develops and publishes textbooks and other educational materials. We all know it as NCERT. It develops and promotes a common curriculum framework for schools in India known as the National Curriculum Framework (NCF). In the recent past years, there have been a lot of up and downs in almost all sectors including education. After the COVID-19 pandemic hit us there have been various changes in the educational sector. The syllabus is modified to have a minimum burden on students to ensure effective learning. With the change in the syllabus, NCERT has also introduced changes in its textbooks.
Here in this article, we have provided the list of content that has been eliminated from the Class 11 NCERT textbooks of all major subjects like Science, Maths, Hindi, English, etc. Also, you don’t have to search for revised NCERT books elsewhere as we have provided the link for the same in this article. Thus, students of CBSE Class 11 read this to know the major changes in their NCERT textbooks. This will be helpful for your examination.

Why Rationalised the NCERT Content?
Contents of the textbooks have been rationalised in view of the following:
- Overlapping with similar content included in other subject areas in the same class
- Similar content included in the lower or higher class in the same subject
- Difficulty level
- Content, which is easily accessible to students without much interventions from teachers and can be learned by children through self-learning or peer-learning
- Content, which is irrelevant in the present context
