Besides, the syllabus also attempts to Strengthen the concepts developed at the secondary stage to provide firm foundation for further learning in the subject. Expose the learners to different processes used in Physics-related industrial and technological applications. Develop process-skills and experimental, observational, manipulative, decision making and investigatory skills in the learners. Promote problem solving abilities and creative thinking in learners. Reducing the curriculum load by eliminating overlapping of concepts/content within the discipline and other disciplines.Promotion of process-skills, problem-solving abilities and applications of Physics concepts.
