CBSE Class 12 Physics Syllabus and Weightage

The CBSE Class 12 Physics Syllabus and Weightage 2026 is a crucial roadmap for students aiming to score high marks in the board examinations. With the board exams rapidly approaching, understanding the exact pattern, chapter-wise distribution, and practical components becomes essential. This comprehensive guide covers the latest CBSE Class 12 Physics Syllabus and Weightage 2026, its exam pattern, marks distribution, and strategic preparation tips to help students excel.


What’s New in the 2026 Physics Syllabus?

Before diving into details, it’s important to note that the syllabus and pattern for the 2026 CBSE Class 12 Physics exam remain aligned with what CBSE published for the 2025–26 academic session. The board has released sample question papers and marking schemes for guidance, and these reflect no major deviations in structure from previous years.

Here’s what you need to know:

  • The exam is divided into theory (70 marks) and practical (30 marks).

  • The theory paper contains multiple choice questions, short answers, long answers, and case study-based questions, all designed to assess comprehension, application, and analytical skills.

  • Practicals include experiments, activities, record work, and viva.
