CBSE Class 12 Physics Syllabus 2026 is divided into nine clear units that explain how electricity, magnetism, light, atoms, and electronic devices work in daily life and technology. The theory exam carries 70 marks, while practical work, such as experiments, activities, projects, and viva, carries 30 marks. Units like Electrostatics, Magnetism, Electromagnetic Waves, Optics, and Modern Physics have higher weightage, so students should prepare them carefully. CBSE has removed several difficult derivations, experiments, and extra theory from chapters like Current Electricity, Magnetism, Optics, and Atoms and Nuclei. Students must study only the updated syllabus to save time and avoid confusion. The chapter-wise syllabus helps students understand each topic step by step, while the practical exam tests observation, accuracy, and understanding of concepts taught in class.
