The CBSE board included significant changes in the curriculum of class XI. In this article, we will be discussing the significant changes made in the subjects Biology, Physics, and Chemistry.
In the current curriculum for class XI aims, the major emphasis was on providing students with updated concepts while ensuring an extended exposure to the contemporary areas of the subject. With the new changes inculcated, the updated curriculum will focus on understanding the scientific principles and their applications.
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.
