Physics is selected as an optional subject by a large number of students in upsc exam. It is mainly selected by people from Engineering backgrounds. Many students find physics as an Interesting subject to study. Cracking the physics optional upsc exam is not a tough job, it’s not easy either. It would require hard work and consistency in studies. A preparation strategy matters a lot for subjects like physics. If you are consistent and determined, passing physics would be an easy job.
