NCERT has significantly updated the Physics textbooks in accordance with the National Education Policy (NEP) in 2020 to provide students with a more contemporary and engaging learning experience. “The reduction in the material will help in increased curriculum flexibility and the renewed emphasis on productivity rather than rote learning,” claims NEP 2020. The new curriculum has been designed to ease the workload and pressure on the students and promote more practical and experiential learning. Source – NEP Final
The NCERT Physics textbooks will be available in at least 22 languages, mentioned in the eighth schedule of the Constitution, including Hindi, English, Bengali, Assamese, Gujarati, Kannada, Sanskrit, Punjabi, Sindhi, Manipuri, Urdu, Malayalam, Odiya, and Kashmiri, among others.

Topics Removed from the Revised Textbooks
Following the implementation of the NEP 2020 policy, around 30% of the content of the NCERT Physics textbook is likely to be rationalised for 2024-2025. MTG consists of a team of experienced authors and subject matter experts who are well-versed with the latest developments in their respective fields. We strive to provide resources that are up-to-date and provide students with the necessary knowledge to succeed in their academic pursuits. We are quick to adapt in regards to the latest revision of the NCERT Physics textbook and will soon include changes consistent with the NCERT on our CBSE Books for Class 12. The table below lists the content that has been dropped from NCERT Physics for class 12 for the academic year 2024–2025.

What is the basis of Content Rationalisation?
According to Union Minister of State for Education Annapurna Devi, “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 children and does not require much intervention from the teachers and can be learned through self-learning or peer learning; content, which is not relevant in the present context or outdated and taking care of the learning outcomes already developed across the classes, are among the criteria adopted for rationalization of the content load.” Source – NCERT textbooks rationalised to compensate for Covid-19 time loss: Education ministry
