Some of the high-weigahge topics were:
- Electromagnetism
- Wave optics
- Derivations
According to Ananya from Bhubaneswar, the long-answer type question confused her. She had to spend maximum time on them.
According to Nitin from the Rourkela centre, the overall paper was moderate; however, he found the numerical question a bit challenging.
Our correspondent Abhay is at the New Delhi exam centre; as he has updated, students are coming out of the exam hall. He will soon gather student reactions and responses on the Physics paper.
As soon as our subject-matter experts get the question paper, they will analyze and provide correct responses. Unofficial keys will be out after 1:30 PM.
Once the invigilators collect all the answer scripts, students will be allowed to leave the exam hall. By 1:15, students will be outside the exam hall.
The Odisha Class 12 Physics 2026 exam concludes at 1 PM. Examinees must stop writing. Invigilators will begin collecting the answer scripts from the students.
The examinees should speed up, as only 15 minutes are left for the exam to conclude. No extra time will be given, so students must revise the paper properly.
