Following the conclusion of the board examinations, the CBSE has published the syllabus encompassing all subjects falling within its curriculum. The recently unveiled syllabi have been meticulously scrutinized and approved by CBSE experts, who have omitted certain topics from the previous syllabus. These modifications align with the 2020 National Education Policy (NEP), which emphasizes a shift towards conceptual comprehension rather than rote learning and exam-oriented education. It is recommended to read the complete NEP guidelines in order to gain a comprehensive understanding of the established norms.
