ISC Class 12 Physics Weightage 2026 Unit and Chapter-Wise Marks Distribution

ISC Class 12 Physics Weightage 2026 : The physics exam is divided into two parts: theory for 70 marks and practical for 30 marks. As per the ISC Class 12 Physics Syllabus 2025-26 , Optics carry the highest weightage, with 18 marks, followed by Electromagnetic Induction and Alternating Currents (16 marks) and Electromagnetic Waves (16 marks). Electrostatics and Current Electricity together carry 15 marks, while Dual Nature of Radiation and Matter is allocated 7 marks. The ISC 12th Physics weightage for the practical exam is divided into 3 components i.e. practical exam, project work, and practical file. The Project work will be assessed by a Visiting Examiner appointed locally and approved by the Council. You will have to do one project involving some physics related topic/s under the guidance and regular supervision of the Physics teacher.
