CBSE Class 12 Physics Exam Pattern 2026 Overview
For the 2025–26 academic session, CBSE maintains a total of 100 marks for Physics: 70 marks for theory (board exam) and 30 marks for practical/internal assessment. The theory paper emphasizes competency-based questions, NCERT-aligned concepts, numericals, and application-based problems.
CBSE Class 12 Physics Paper Pattern 2026 (Theory – 70 Marks)
-
Mode of exam: Pen-and-paper (offline)
-
Duration: 3 hours
-
Total marks (theory): 70
-
Total questions: Around 33, divided into 5 sections (A–E)

CBSE Class 12 Physics Preparation Tips 2026
-
Prioritize high-weightage units: Electrostatics, Current Electricity, Magnetic Effects of Current & Magnetism, Electromagnetic Induction & AC, Optics, Dual Nature of Matter and Radiation, Atoms & Nuclei, and Electronic Devices.
-
Study NCERT textbooks (Part I & II) thoroughly, including line-by-line concepts, examples, derivations, and in-text questions—many board questions are directly NCERT-based.
-
Solve previous year papers and sample papers in timed conditions to master speed, accuracy, and the competency-based format.
-
Maintain a dedicated notebook for formulas, derivations (especially in optics, electrostatics, current electricity, and magnetism), and revise it frequently.
-
Practice numericals from NCERT, Exemplar problems, and objective books to tackle MCQs and application questions effectively.
Recommended Books for CBSE Class 12 Physics
-
NCERT Physics Class 12 (Part I & II) – Essential for concepts and board-level questions.
-
