**Prelude to UPSC Physics Syllabus**

Note First and foremost, you must talk to someone who has taken Physics as an optional earlier and take their advice. There has been a common misconception among the students that UPSC Physics Syllabus is a hard nut to crack and its better to leave it as an optional paper. You are absolutely wrong.

Even through the Physics Syllabus portion in UPSC looks very huge and hard to study, once you start reading through few chapters, you will come to an absolute conclusion that UPSC Physics Syllabus is one of the most interesting and easiest of all the papers in entire UPSC Syllabus.

**Physics Syllabus Tips from Ranker**

It is highly possible to clear UPSC Mains exam when taking Physics as optional but it is possible in single situation if Physics is your favorite subject or you are best in subject and you are familiar with the subject

Physics could prove to be very high scoring and if you have read it in grad,it will take you less time to cover the syllabus and in turn the revisions as well.

Go through the UPSC Physics syllabus and check if you’re well-versed with all the topics mentioned in the syllabus.

Physics is a good subject I too had the same subject and was very successful inspite of not joining coaching.

**Conclusion on UPSC Mains Physics Syllabus**

It is always said that the wise men words are often neglected. However, we would like to again stress the fact that the Physics Syllabus in UPSC is one of the most important and crucial things that has to be properly taken care of.

Not just for examination point of view, Physics Syllabus in UPSC helps you in the overal development to become a good responsible officer who will play a crucial role in the development of the country in the decades to come.

Physics can be a good optional if you are extremely brilliant at it but i do have a few problems. Physicsis not going to help an ias in any possible way.

There has been a news circulating that, UPSC may remove optionals in coming years.mind you its not a rumor but actual happening in near future.
