 # Punjab Board Class 12 Physics Syllabus

Since its inception, the Punjab School Education Board has been striving to provide world-class education in Science. By adopting novel methods such as introducing major scientific developments in the syllabus and following the guidelines laid down by the National Curriculum Framework 2005, the board has set a credible PSEB Class 12 Physics syllabus that puts the students on a path towards higher education.

The Punjab Board Class 12 Physics Syllabus has all the required components for a great foundation before the students can choose engineering or other academic courses. The board has adopted a future focus curriculum so that the topics are included in the syllabus before they are in demand in the industry.

From the links given below in this article. students can access the PDF version of the PSEB Class 12 Physics Syllabus 2021-22. We have also provided the snapshot of the unit wise marks distribution of the previous year.

Physics subject is not complete if experiments and practicals don’t go hand in hand with theory classes. To this extent, the Punjab board has included a right mix of practicals in the syllabus, so the students can also gain application perspective.
