Table of Contents
The Jharkhand board has made considerable changes to the 12th-grade Physics curriculum. Since the COVID-19 pandemic, the JAC 12th Physics syllabus has changed several times in an attempt to lessen the academic stress of students like you and to make the studies more productive and practical. Some challenging and repetitive chapters and topics have been removed to let you focus on the main physics concepts and laws for the JAC 12th Exam 2026 and other competitive exams like JEE.
To properly study for the upcoming board exams, it is advised that you go over the JAC 12th Deleted Syllabus 2026. Removing some of the curriculum would make it easier for you to learn and revise all the topics from the syllabus before the board exams. The Jharkhand board's official website, jac.jharkhand.gov.in, has the revoked curriculum. For those of you who will be sitting your 12th boards in the academic year 2025–2026, this post contains the JAC 12th Physics Deleted Syllabus 2026.
