CBSE Class 12 Physics 2025: Most Repeated Questions from Past Years for Board Exam

The Central Board of Secondary Education (CBSE) has released the datesheet for class 10th and 12th students appearing for the 2025 board exams. As per the timetable, the class 12th Physics board exam 2025 is scheduled on February 21, 2025.

With less than three months left for preparation, students are preparing hard for this important exam. To help them with the CBSE class 12 Physics board exam 2025, a set of repeated questions has been compiled.

While these expert tips will add value to the preparation, students are advised to complete their syllabus thoroughly and practice questions from textbooks, sample papers, model papers, and previous years’ question papers available on the official website of the board.
