The senior secondary stage of schooling is a phase of transition from general education to a discipline-based focus on the Curriculum. The current updated curriculum takes into account the rigour and depth of the disciplinary approach as well as the level of understanding of the learners. Care has also been taken that the curriculum is at par with international standards. Key features of the course include:
- Emphasis on basic conceptual understanding of the material.
- Emphasis on the use of SI units, symbols, the nomenclature of physical quantities, and formulations as per international standards.
- To provide logical sequencing of the units of content and proper placement of concepts with their associations for better learning.
- Reducing syllabus load by eliminating overlapping of concepts/content within the discipline and other disciplines.
- To promote process skills, problem-solving abilities, and applications of physics concepts.
