Which topics should I focus most for Physics Class 12 CBSE board exam?

You should focus most on Electrostatics, Current Electricity, Magnetism, Optics, Dual Nature of Matter, Atoms & Nuclei because these chapters carry maximum marks and are repeatedly asked in CBSE board exams.

Why Focus on Selected Topics?

The Class 12 Physics syllabus is vast, but the exam paper is predictable. Some topics have more weightage and are easier to revise. By concentrating on them, you can maximize your marks with minimum effort. This strategy is especially useful if you have limited preparation time.

High-Weightage Chapters (with Marks Distribution)

Most Important Topics for Class 12 Physics

• Electrostatics: Electric field, potential, capacitors.
• Current Electricity: Ohm’s law, Kirchhoff’s laws, circuits.
• Magnetism: Biot–Savart law, moving coil galvanometer.
• Optics: Ray diagrams, interference, diffraction, polarization.
• Dual Nature: Photoelectric effect, de Broglie wavelength.
• Atoms & Nuclei: Rutherford’s model, nuclear reactions.
• Communication: Modulation techniques, bandwidth.

Study Strategy for Maximum Output

1. Revise NCERT thoroughly: Most CBSE questions come directly from NCERT.
2. Practice derivations: Especially in Electrostatics, Optics, and Magnetism.
3. Solve past 10 years’ question papers: Many questions are repeated.
4. Make formula charts: Revise them daily in the last 2 months.
5. Focus on easy theory chapters: Communication Systems and Nuclei are scoring.
