UP Board Physics Class 12 syllabus
UP Board Physics Class 12 syllabus

The class 12th physics is a vital subject in the curriculum. Thus, with the ongoing pandemic, the UP board has reduced the syllabus by 30%. The revised syllabus is based on the basics and advanced concepts of physics that will help the student develop knowledge and the right skills. The physics concept of the revised syllabus is based on the NCERT textbooks, which will also be beneficial for the student to develop a practical approach for the topics discussed. For the theory exam, the students will have only one paper to write. Whereas, the old syllabus had two papers that were lengthy as well.

The following information is for class 12 students to get acquainted with the physics syllabus to prepare for their exams accordingly.
