The CBSE Class 12 Board Exams 2025 are underway, with the Physics exam scheduled for February 21, 2025. With just a day left, students must focus on key topics, practice previous year’s papers, and revise crucial numerical problems to score well.
As per CBSE’s 2024-25 sample paper, the Physics question paper will: contain 30 compulsory questions, be divided into five sections (A to E), carry a total of 70 marks and have a 3-hour duration.
Question paper pattern: 20% multiple-choice questions (MCQs) 30% competency-based questions in the form of MCQs, case-based questions, source-based integrated questions, etc. 50% short/long answer questions
Why is solving previous year papers crucial? Practicing CBSE Class 12 Physics Question Papers from previous years helps students to: Understand the exam pattern & marking scheme Identify high-weightage topics Improve speed & accuracy Boost confidence by attempting real exam-like questions
Previous year's question papers and sample papers can be downloaded from the CBSE website.
Key theoretical concepts to revise Electrostatics & Current Electricity – Electric dipole, Gauss’s law, drift velocity Magnetism & Electromagnetic Induction – Moving coil galvanometer, AC generator, transformer Optics – Refraction, prism, Young’s double-slit experiment, compound microscope, telescope Modern Physics – Atomic structure, PN diode, rectifier, energy of an electron in orbit Electromagnetic Waves – Properties of magnetic materials, electromagnetic wave characteristics
Important numericals & graph-based questions Numericals on – Electric field, capacitance, circuits, magnetic field, force, interference fringe width Graph-based questions on – Resistivity vs temperature, photoelectric effect, stopping potential
