UK Board 12th Syllabus Physics 2024: The Uttarakhand Board has released the syllabus for the session year 2023-24. Students are busy with preparation, but it’s important to know what they need to study. Some topics have been revised or deleted, and students need to stay updated.

It’s better not to overprepare and confuse yourself in the exams, especially in difficult subjects like physics. The UK Board syllabus for physics is vast already and requires consistent practice and understanding of the subject.

Here at Jagran Josh, you can view and download the pdf of the UBSE Class 12 physics syllabus, along with the blueprint and marks distribution.
