For the academic year 2021-22, the Central Board of Secondary Education (CBSE) has incorporated some changes to the curriculum. It included rationalization of the syllabus and distributing the same between two terms. In this article, we shall know about the topics assigned in the subjects (Biology, Physics, and Chemistry) for class XII.
The updated curriculum of the syllabus is expected to promote great exposure to the various topics to the students. We will learn how it helps in more contextual and systematic learning of the topics in the units.
