CBSE 12th Physics Most Repeated Topics 2025: The Central Board of Secondary Education (CBSE) has scheduled to conduct the 12th exams from February 15 and April 4, 2025, in pen and paper format. Candidates can check the CBSE 12th Physics Most Repeated Topics 2025 here for their reference. Magnetic Dipole and Magnetic Field lines are not among the repeated topics, however, in 2023 and 2024 1 mark questions were asked from the topic, whereas in 2022, a two-mark question was asked. Moreover, the candidates are advised to carefully study and revise the mentioned topics to increase the chances of them scoring well. The CBSE 12th Physics Most Repeated Topics 2025 are available here for Book 1 and 2.
