When it comes to exam preparation, following the latest and updated syllabus is crucial for achieving a high score. Just like boarding a bus or train with an outdated ticket can land you in trouble, studying the wrong syllabus can be equally detrimental to your exam performance.
In light of the pandemic, educational authorities have recognized the need for changes in the traditional syllabus. These changes include additions, deletions, and modifications of topics, exercises, and entire units. To ensure effective exam preparation and successful completion of the academic year, it is essential to stay informed about the modifications made by CBSE to the syllabus for your subjects.
The new CBSE syllabus for the academic year 2023-24 has been reduced by 30% compared to the pre-COVID syllabus. This reduction aligns with the National Education Policy 2020 (NEP), which aims to ease the burden on students and facilitate college admissions by reducing the weightage of board exams.
According to the NEP, the curriculum content will focus on core essentials, fostering critical thinking, holistic learning, inquiry-based approaches, discovery-based learning, discussions, and analysis. The mandated content will emphasize key concepts, ideas, applications, and problem-solving skills. For a detailed understanding of the changes, refer to the NEP guidelines of 2020.
In this post, our primary focus is on the updated syllabus for CBSE Class 11 Physics. We will provide information about the deleted topics, exercises, questions, and units. Additionally, we will highlight the new topics recently added to the CBSE Physics syllabus for Class 11. Keep reading to stay informed about the updated Class 11 Physics syllabus.
