Examining Class 11 Physics syllabus

Senior Secondary school education is a transitional step from general education to a discipline-based curriculum concentration. The current curriculum of Class 11 Physics takes into account the rigour and complexity of the disciplinary approach, as well as the learners’ comprehension level. Class 11 Physics syllabus has also been carefully crafted to be similar to international norms.

The following are some of the Class 11 Physics syllabus’s most notable features:

1. Emphasis is placed on gaining a fundamental conceptual knowledge of the material.
2. Use of SI units, symbols, naming of physical quantities, and formulations in accordance with international standards are emphasised.
3. For enhanced learning, provide logical sequencing of subject matter units and suitable placement of concepts with their links.
4. Eliminating overlapping concepts/content within the field and between disciplines to reduce the curricular load.
5. Process skills, problem-solving ability, and the application of Physics principles are all encouraged.
