The West Bengal Council of Higher Secondary Education (WBCHSE) has released the WBCHSE Class 12 Physics syllabus for the academic year 2025-26. The curriculum is divided into two semesters: Semester III and Semester IV. Each semester includes both theoretical and practical components, along with provisions for project work and internal assessment. Students preparing for the board exams must understand the unit-wise structure, marks allocation, and practical guidelines to prepare effectively.
