ISC Class 12 Physics Exam Pattern 2024-25
: In physics, students will have to appear for a 70-mark theory paper and a 30-mark practical exam. In the theory paper, students will get questions divided into 4 sections, i.e., A, B, C, and D. Internal choices are provided in two questions each in Sections B, C, and D. Section A will have 1 mark question; sections B, C, and D will have 7 questions of 2 marks each, 9 questions of 3 marks each, and 3 questions of 5 marks each, respectively.
Students are also advised to check the
