Punjab Board Class 12th Chemistry Syllabus: PSEB has released the revised and latest syllabus for its Class 12 students on its official website. The curriculum has been updated for almost 40 subjects. We will bring to you the syllabus for each subject along with a PDF of the same. In this article, you can find the PSEB Class 12 Chemistry Syllabus 2025 and get to know about the units, chapters, and topics that are going to be a part of the curriculum this year. The PDF download link provided below is available for free download, hence anyone can download it by clicking on the link attached in the box.
The syllabus has been categorised into multiple units, each being important for the board exam. The details regarding marks weightage held by each unit, exam pattern to be followed in the paper, and more will be updated by PSEB, as we move ahead in the academic journey and progress towards the board exams. For now, the [unjab Board 12th Chemistry syllabus 2025 has been attached here for your reference.
